Contact - Kontakt - Contact - Contacter.................................................................................................................................................................................................. 371Important to read before the first ride The most important points for you to do 1. Even if you have ridden a bicycle for years, it is important for every person to read the general “Bike Owner’s manual” and the specific “Electric Bicycle Owner’s manual” carefully before you ride on the new e-bicycle.

• Both manuals contains detailed information and useful suggestions about your new bicycle.

• Make sure that you understand the proper use, maintenance, and disposal of the components of the electrical system of your new e-bicycle.

2. Think about safety. Your safety and that of other road users is very important.

• Do not ride the electric bike without the battery pack. The battery pack must be on the bike while riding, else the bike has no lights when needed.

• Do not misuse the electric bike by riding it without a saddle. Some bikes have a quick release on the seat post. If the saddle gets stolen, it may lead to hazardous situations when still riding on the electric bike without a saddle.

• Check your bike for normal operation, loose parts and defects before riding. If you find any problem, visit your bike dealer for repairs before riding.

• Be aware that other road users do not expect that an electric bike can ride faster than a normal bike. Riding faster also increases the risk of accidents.

• Do not ride abusively. Only ride in the use conditions specified for your bike. Condition 1 (paved roads with tires staying on the ground) is valid for electric City/Trekking bikes, condition 3 (rougher surfaces, tires momentarily NOT on the ground ) is valid for electric Mountain bikes. Please refer to the general Bicycle Owner’s manual for more detailed information.

• Do not over load the rear rack. The maximum allowable weight for the rear rack on electric bikes is 20 kg for bikes with a rear rack battery pack and 25 kg for bikes with a down tube battery. On bicycles with a luggage rack at both sides of the rear fender only, without a top deck, the maximum allowed load on the rack is 15 kg in total.

3. The electric system of your new bicycle needs special attention.

• Do not clean your electric bicycle with a high pressure washer. Any electric system is sensitive for moisture. High pressure water might ingress in connectors or other parts of the electric system.

• Handle your battery pack with care. Do not drop or impact the battery pack. Mishandling of the battery pack could lead to severe damage or over-heating. In an extremely rare case, a battery pack that has been severely impacted or otherwise mishandled could potentially catch fire. If you suspect damage to your battery pack, visit your dealer immediately for inspection.

4. Maintain the battery pack as instructed in this Electric Bicycle Owner’s manual.

Failure to follow these instructions may result in damage to your battery pack and may require battery pack replacement:

• Only charge the battery pack with the included Bosch charger.

• When not using the battery pack for a longer period, charge it to approx. 60 % (3 to 4 LEDs lit on the charge-control indicator). Check the charge condition after 6 months. When only one LED of the charge-control indicator lights up, recharge the battery pack again to approx. 60 %.

• It is not recommended to have the battery pack connected permanently to the charger.

• When the battery pack is stored discharged (empty) for longer periods, it can become damaged despite the low selfdischarging and the battery-pack capacity may be strongly reduced.

• Store the battery pack in a dry, well-ventilated location. Protect the battery pack against moisture and water.

• Under unfavorable weather conditions, it is recommended e.g. to remove the battery pack from the bike and store it in an enclosed location until being used again.

• Store the battery packs in the following locations: in a room with a smoke alarm, away from combustible or easily flammable objects and away from heat sources.

• The battery pack can be stored at temperatures between -10°C and +60°C. For a long battery pack life, however, storing the battery pack at room temperature of approx. 20°C is of advantage. 5• Take care that the maximal storage temperature is not exceeded. As an example, do not leave the battery pack in a vehicle in summer and store it out of direct sunlight.

• It is recommended to not store the battery pack on the bike.

5. Be careful when transporting an electric bicycle.

• An e-bike is heavier than a normal bike. If transporting on a vehicle, be aware of the maximum load capacity of the vehicle’s roof, towing hook and/or of the applied bike carrier. Refer to the manual of the vehicle and bike carrier for details.

• Remove the controller, battery pack and, if present, panniers from the bicycle and store them elsewhere in the vehicle during the drive.

• Always respect local laws about transportation of a(n electric) bicycle.

• Because Li-Ion battery packs of this size and power are considered ‘Dangerous goods, class 9’ when transporting, regulations may restrict the transport of separate Li-Ion batteries in some places. The restrictions apply to most airlines and some trucking companies. But, if you intend to ship or travel with your complete e-bike (with installed battery pack), the regulations are less strict. Make sure to check ahead with your airline or carrier, before booking your trip, if it is allowed to travel with your complete e-bike.

6. Mounting accessories on an e-bike.

An electric bike has hidden wiring through frame and has other critical e-bike parts like the drive unit and battery pack. When mounting accessories (e.g. a bottle cage), be sure not to impact the wiring or battery pack, e.g. by using too long or pointed bolts. This might cause a short circuit to the electric system and/or damage to the battery. WARNING. A short circuit in the electric system and/or damage to the battery might lead to over-heating. In an extremely rare case, a battery pack that has been severely impacted could potentially catch fire.

7. Visit your dealer on a regular basis for maintenance of your new e-bike.

• To guarantee the safe and proper functioning of the bike, the bike must be maintained on a regular basis, at least once a year, by an authorized electric bicycle dealer.

• Your dealer has the right knowledge and equipment to maintain your e-bike and to mount accessories safely.

• If you have questions about your new electric bicycle, ask your dealer! Compliance Your bicycle has been designed, tested, and produced in accordance with the applicable European Directives and Harmonised Standards. Therefore, all electric bicycles are in compliance with CE. For more detailed compliance information, please refer to the Declaration of Conformity (DoC) which was included along with your bicycle. If you have misplaced your DoC, a new one can be furnished upon request, by the bicycle shop at which you purchased your electric bicycle. Limited warranty Your bicycle is covered by a Lifetime Limited Warranty. Please visit our web site for details. 6Additional information for ‘Fast Electric Bicycles’* The Fast Electric Bicycle is an electric bicycle that provides assistance that does not stop at 25 km/h. The maximum assisted speed is higher than that provided by a standard Pedelec. Note, though, that the actual maximum speed that you can reach depends first and foremost on how strongly you pedal. *‘Fast’ Electric bicycles are not available in all European countries. European Type Approval Legally, the Fast Electric Bicycle is no longer considered a ‘bicycle’ but an ‘electric motor vehicle’. It has European Type Approval (Class L1e-B) as such, with regards to Directive (EU)168/2013. Each Fast Electric Bicycle has a Type-approval plate on the frame and a unique VIN number (VIN = Vehicle Identification Number). The technical equipment of these Fast Electric Bicycles is almost identical to that on 25 km/h Pedelecs. The following parts are additional and/or different:

• Rear view mirror • Insurance plate / license plate and holder for this plate • License plate light • Extra reflectors

• Slightly different brake levers • Rear brake light • Horn • Type approved front and rear lights. NOTICE. These parts are all part of the type approval. It is not allowed to remove or exchange them for other (non-certified) equipment. This also applies to the fork, tires, kickstand, motor, battery pack and display. WARNING. Speed Pedelecs built after January 1, 2018 have to comply with new requirements. As a result, they must be delivered to the market with the front brake lever located on the right hand side of the handlebars and the rear brake lever on the left hand side*. Be aware that this can differ from the configuration on a regular bicycle! *IMPORTANT NOTICE. In your country, it may legally not be allowed to change this configuration after the bicycle has been delivered. Please obey the local rules. Local legislation/rules*

• The legal rules to use a Fast Electric Bicycle vary per country.

• As a Fast Electric Bicycle is legally seen as an electric motor vehicle, you will have to comply with the local legal rules about the minimum age of the rider, driving license, insurance, insurance /license plate, traffic and maximum speed regulations, etc.

• For a Fast Electric Bicycle, third party insurance is mandatory.

• In many countries, wearing a helmet is mandatory for these bicycles. Even, when wearing a helmet is not mandatory in your country, we strongly recommend to always wear a helmet for your own safety. *NOTICE. The local legislation/ rules may be subject to changes in time. Advice for use

• Technically, riding is the same as the Pedelec bicycles, except that the assistance does not stop at 25 km/h.

• Your Fast Electric Bicycle can still be ridden as a bicycle. On the road, you will usually have to obey the rules for mopeds, however, even if you ride without assistance.

• The maximum range on one battery charge depends very much on your style of use.

• Due to the higher speed that can be reached, be prepared to find the range slightly shorter than on regular Pedelec bicycles that have a maximum assistance speed of 25 km/h.

Failure to observe the safety in- formation and follow instructions may result in electric shock, fire and/or serious injury. Save all safety warnings and instructions for future ref- erence. The term battery is used in these instructions to mean all original Bosch eBike rechargeable battery packs. u Read and observe the safety warnings and directions contained in all the eBike system operating instruc- tions and in the operating instructions of your eBike. u Do not allow yourself to be distracted by the on-board computer's display. If you do not focus exclusively on the traffic, you risk being involved in an accident. If you want to make entries in your on-board computer other than switching the assistance level, stop and enter the ap- propriate data. u Do not use the on-board computer as a handle. Lifting the eBike up by the on-board computer can cause irrepar- able damage to the on-board computer. u When using the walk assistance, make sure that you can control the eBike and that you can hold it securely at all times. Under certain circumstances, the walk as- sistance may stop (e.g. if the pedals hit an obstacle or if you accidentally let go of the button on the operating unit). The eBike may suddenly move backwards onto you or tip up. This presents a risk for the user particularly if there is additional load on the eBike. When using the walk assistance, do not bring the eBike into situations in which you cannot hold the eBike using your own strength.

Bosch eBike Systems 1 270 020 XBI | (29.11.2021) 21English – 2 Fitting Inserting and removing the battery For inserting and removing the eBike battery in/from the eBike, please read and observe the battery operating in- structions. Fitting and removing the on-board computer (seefigureA) To fit the on-board computer (3), slide it forwards into the holder (4). To remove the on-board computer (3), press the locking mechanism (14) and slide the on-board computer forwards out of the holder (4). u Remove the on-board computer when you park the eBike. The on-board computer can be secured in place to prevent it from being removed from the holder. To do so, remove the holder (4) from the handlebars. Put the on-board computer in the holder. Screw the locking screw (15) (M3 thread, 8mm long) from below into the thread provided in the holder. Mount the holder back onto the handlebars. Please note: The locking screw is not designed to prevent theft. Operation Prerequisites The eBike system can only be activated when the following requirements are met: – A sufficiently charged battery is inserted (see battery op- erating instructions). – The on-board computer is properly inserted in the holder (see "Fitting and removing the on-board computer (seefigureA)", pageEnglish – 2). – The speed sensor is connected properly (see drive unit operating instructions). Switching the eBike system on/off The following options are available for switching on the eBike system: – If the on-board computer is already switched on when you insert it into the holder, the eBike system will be activated automatically. – Once the on-board computer and the eBike battery are fitted, briefly press the on/off button on the on-board computer. – With the on-board computer inserted, push the on/off button on the eBike battery (bicycle manufacturer-spe- cific solutions are possible when there is no access to the battery on/off button; see the battery operating instruc- tions). The drive is activated as soon as you start pedalling (except if you are using the walk assistance function or if the assist- ance level is set to OFF). The motor output adjusts to the as- sistance level set. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25/45km/h, the eBike drive switches off the assistance. The drive is automat- ically reactivated as soon you start pedalling again and the speed is below 25/45km/h. The following options are available for switching off the eBike system: – Press the on/off button of the on-board computer. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). – Remove the on-board computer from its holder. If no power is drawn from the eBike drive for about10minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the con- trol unit of the eBike, the eBike system will switch off auto- matically. eShift (optional) eShift is the integration of electronic gear-shifting systems into the eBike system. The eShift components are electric- ally connected to the drive unit by the manufacturer. The separate operating instructions describe how to operate the electronic gear-shifting systems. Energy supply of the on-board computer If the on-board computer is in the holder (4), a sufficiently charged battery is inserted in the eBike and the eBike sys- tem is switched on, then the on-board computer is powered by the battery of the eBike. If the on-board computer is removed from the holder (4), the energy is supplied via an internal battery. If the internal battery is weak when the on-board computer is switched on, <Attach to bike> will appear on the text indicator (d) for 3s. The on-board computer will then turn off again. To charge the internal battery, put the on-board computer back in the holder (4) (when a battery is inserted in the eBike). Switch the eBike battery on by its on/off button (see battery operating instructions). You can also charge the on-board computer via the USB port. To do this, open the protective cap (8). Connect the USB port (7) of the on-board computer via a suitable USB cable to a standard USB charger or the USB port of a com- puter (5 V charging voltage, max. 500 mA charging current). <USB connected> will appear on the text indicator (d) of the on-board computer. 1 270 020 XBI | (29.11.2021) Bosch eBike Systems 22English – 3 Switching on/shutting down the on-board computer To switch on the on-board computer, briefly press the on/ off button (5). The on-board computer can also be switched on when it is not inserted in the holder (if the internal battery is sufficiently charged). To switch off the on-board computer, press the on/off but- ton (5). If the on-board computer is not inserted in the holder, it automatically switches off after 1minute to save energy if no button is pressed. u If you are not going to be using your eBike for several weeks, remove the on-board computer from its holder. Store the on-board computer in a dry environ- ment at room temperature. Regularly recharge the on- board computer's battery (at least every 3 months). Battery charge indicator The battery charge indicator (i) displays the state of charge of the eBike battery, not that of the on-board computer's in- ternal battery. The state of charge of the eBike battery can also be checked on the LEDs of the battery itself. Each bar of the battery symbol on the indicator (i) repres- ents approximately 20% of the capacity: The eBike battery pack is fully charged. The eBike battery pack should be recharged. The LEDs of the battery charge indicator on the battery go out. The capacity for assisting the drive has been used up, and assistance is gently switched off. The remaining capacity is made available for the lighting and the on- board computer. The indicator flashes. The ca- pacity of the eBike battery is enough for about two hours of lighting. This does not account for other consumers (e.g. automatic gearbox, char- ging external devices at the USB port). If the on-board computer is removed from the holder (4), the last displayed state of charge of the battery is saved. If an eBike is powered by two batteries, the battery charge in- dicator (i) displays the state of charge of both batteries. OFF MPH KM/H If an eBike has two batteries inserted into it and both batteries are charged on the bike, the charging progress of both bat- teries will be indicated on the display (the left-hand battery pack is being charged in the illustration). You can also tell by the flashing indicator on the bat- tery which of the two batteries is being charged. Setting the assistance level On the operating unit(9), you can set the level of assistance you want the eBike drive to provide you with while pedalling. The assistance level can be changed at any time, even while cycling. Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here. The following assistance levels are available as a maximum: – OFF: Motor assistance is switched off. The eBike can only be moved by pedalling, as with a normal bicycle. The walk assistance cannot be activated at this assistance level. – ECO: Effective assistance with maximum efficiency, for maximum range – TOUR/TOUR+: TOUR: Steady assistance, long range for touring TOUR+: Dynamic assistance for natural, sporty cycling (only in conjunction witheMTB) – SPORT/eMTB: SPORT: Powerful assistance, for mountain biking and cycling in urban traffic eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dy- namics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX. A software update may be required.) – TURBO: Maximum assistance even at a high cadence, for sporty cycling To increase the assistance level, press the + button(12) on the operating unit repeatedly until the required assistance level appears on indicator (b). To decrease the assistance level, press the – button(11). The requested motor output is displayed in the indicator (a). The maximum motor output depends on the selected assist- ance level. When the on-board computer is removed from the holder (4), the assistance level that was last displayed is saved; the motor output indicator (a) remains empty. Interaction between the eBike system and gear- shifting The gear shifting should be used with an eBike drive in the same way as with a normal bicycle (observe the operating in- structions of your eBike on this point). Irrespective of the type of gear shifting, it is advisable that you briefly reduce the pressure on the pedals when changing gear. This will aid gear shifting and reduce wear on the powertrain. By selecting the correct gear, you can increase your speed and range while applying the same amount of force. For this reason, follow the gear change recommendations provided by the indicators (g) and (h) on your display. If in- dicator (g) is displayed, you should change to a higher gear with lower cadence. If indicator (h) is displayed, you should select a lower gear with higher cadence. Switching bike lights on/off On the model on which the lighting is powered by the eBike system, the front and rear lights can be switched on and off at the same time via the on-board computer using the bike light button(2). Bosch eBike Systems 1 270 020 XBI | (29.11.2021) 23English – 4 Check that your bike lights are working correctly before every use. When the lighting is switched on, <Lights on> appears and when the lighting is switched off, <Lights off> appears for approx. 1s on the text indicator (d). The lighting symbol (c) is displayed when the light is on. The on-board computer saves the light status and activates this saved status accordingly after a restart. Switching the bike lights on and off has no effect on the backlighting of the display. Switching the push assistance on/off The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6km/h. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. To activate the walk assistance, briefly press the WALK but- ton on your on-board computer. Once it is activated, press the + button within 10s and keep it held down. The eBike drive is now switched on. Note: The push assistance cannot be activated at assistance level OFF. The push assistance is switched off as soon as one of the following occurs: – You release the +button; – The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle); – The speed exceeds 6km/h. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Powering external devices via the USB port The USB port can be used to operate or charge most devices that can be powered via USB (e.g. various mobile phones). Charging requires the on-board computer to be mounted and a sufficiently charged battery to be inserted in the eBike. Open the protective cap(8) for the USB port on the on- board computer. Use a Micro-A – Micro-B USB charging cable (available from your Bosch eBike dealer) to connect the USB port on the external device to the USB port(7) on the on-board computer. Once the electrical load has been disconnected, the USB port must be carefully resealed with the protective cap(8). u USB connections are not waterproof. When cycling in the rain, do not connect any external devices and make sure that the USB port is fully sealed by the pro- tective cover(8). Important: If electrical loads are connected, this can affect the range of the eBike. Displays and configurations of the on-board computer Speed and distance indicators The speedometer (f) always displays the current speed. You can choose from the following functions in the function display (combination of text indicator (d) and value indic- ator (e)): – <Clock>: Current time – <Max. speed>: Maximum speed achieved since the last reset – <Avg. speed>: Average speed achieved since the last re- set – <Trip time>: Journey time since the last reset – <Range>: Estimated range of the available battery charge (at constant conditions such as assistance level, route profile, etc.) – <Odometer>: Total distance travelled with the eBike (cannot be reset) – <Trip distance>: Distance travelled since the last reset To switch between display functions, press the ibut- ton(1) on the on-board computer or the ibutton(10) on the operating unit repeatedly until the required function is dis- played. To reset the <Trip distance>, <Trip time> and <Avg. speed>, switch to one of these three functions and then press the RESET button (6) until the indicator is set to zero. This will also reset the values of the other two functions. To reset the <Max. speed>, switch to this function and then press the RESET button (6) until the indicator is set to zero. To reset the <Range>, switch to this function and then press the RESET button (6) until the indicator is reset to the value of the factory setting. If the on-board computer is removed from the holder (4), all values of the functions are saved and can still be displayed. Displaying/adjusting basic settings The basic settings can be displayed and changed regardless of whether the on-board computer is inserted in the holder (4) or not. Some settings can only be viewed and changed when the HMI is inserted. Depending on the equipment of your eBike, some menu items may not be present. To go to the basic settings menu, simultaneously press the RESET button (6) and the i button (1) until <Configura- tion> appears on the text indicator (d).

IP54 (dust and splash- proof) Weight, approx. kg 0.1 A) We recommend using the batteries offered by Bosch. You can purchase them from your bicycle dealer (article number: 1 270 016 819). B) When the USB cover is closed The Bosch eBike system uses FreeRTOS (seehttp://www.freertos.org

Operation Symbols and their Meaning Symbol Explanation Short button press (less than 1 second) Medium button press (between 1 second and 2.5 seconds) Long button press (longer than 2.5seconds) Start-up Prerequisites The eBike system can only be activated when the following requirements are met: – A sufficiently charged battery is inserted (see battery op- erating instructions). – The speed sensor is connected properly (see drive unit operating instructions). Switching the eBike system on/off The following options are available for switching on the eBike system: – Press the on/off button (1) of the on-board computer with the eBike battery inserted. – Press the on/off button of the eBike battery (see battery operating instructions). The drive is activated as soon as you start pedalling (except if you are using the walk assistance function or if the assist- ance level is set to OFF). The motor output adjusts to the as- sistance level set. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25/45km/h, the eBike drive switches off the assistance. The drive is automat- ically reactivated as soon you start pedalling again and the speed is below 25/45km/h. The following options are available for switching off the eBike system: – Press the on/off button (1) of the on-board computer. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). The system shuts down after being switched off. This takes approximately 3seconds. It cannot be switched back on un- til shutdown has been completed. If the eBike is not moved for approx. 10 min and no button is pressed on the on-board computer, the eBike system switches off automatically in order to save energy. Note: Always switch off the eBike system when you park the eBike. Note: If the batteries of the on-board computer are empty, you can still switch on your eBike using the bike’s battery. It is, however, recommended that you replace the internal bat- teries as soon as possible in order to avoid damage. Energy supply of the on-board computer The on-board computer is supplied with voltage by two CR2016 button cells. Changing the batteries (see figure A) If the on-board computer shows LOW BAT on the display, remove the on-board computer from the handlebars by un- screwing the fastening screw(3) of the on-board computer. Open the battery compartment cover(10) using a suitable coin, remove the used batteries and insert new CR2016 bat- teries. You can obtain the batteries recommended by Bosch from your bicycle dealer. When inserting the batteries, ensure that the polarity is cor- rect. Close the battery compartment again and fasten the on- board computer to your eBike’s handlebars using the fasten- ing screw(3). Switching the push assistance on/off The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6km/h. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. To activate the walk assistance, briefly press the WALK but- ton on your on-board computer. Once it is activated, press the + button within 10s and keep it held down. The eBike drive is now switched on. Note: The push assistance cannot be activated at assistance level OFF. The push assistance is switched off as soon as one of the following occurs: – You release the +button; 1 270 020 XBP | (23.11.2021) Bosch eBike Systems 60English – 3 – The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle); – The speed exceeds 6km/h. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Setting the assistance level You can set the level at which the eBike drive assists you while pedalling on the on-board computer. The assistance level can be changed at any time, even while cycling. Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here. The following assistance levels are available as a maximum: – OFF: Motor assistance is switched off. The eBike can only be moved by pedalling, as with a normal bicycle. The walk assistance cannot be activated at this assistance level. – ECO: Effective assistance with maximum efficiency, for maximum range – TOUR/TOUR+: TOUR: Steady assistance, long range for touring TOUR+: Dynamic assistance for natural, sporty cycling (only in conjunction witheMTB) – SPORT/eMTB: SPORT: Powerful assistance, for mountain biking and cycling in urban traffic eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dy- namics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX. A software update may be required.) – TURBO: Maximum assistance even at a high cadence, for sporty cycling To increase the assistance level, briefly press the but- ton+ (6) on the on-board computer repeatedly until the re- quired assistance level appears on the indicator (i). To de- crease the assistance level briefly press the button– (5). If the display is set to TRIP, TOTAL or RANGE, the selected assistance level will only be superimposed briefly(for ap- prox. one second) on the display when switching over. Switching bicycle lights on/off On the model in which the bike lights are powered by the eBike system, pressing the button+ for a medium length of time will switch on the front and rear lights simultan- eously. Pressing the button+ for a medium length of time will switch the lights off again. The lighting symbol (h) is displayed when the light is on. Check that your bike lights are working correctly before every use. The on-board computer saves the light status and activates this saved status accordingly after a restart. Switching the bike lights on and off has no effect on the backlighting of the display. Bosch eBike Systems 1 270 020 XBP | (23.11.2021) 61English – 4 Displays and configurations of the on-board computer Battery charge indicator The battery charge indicator (g) displays the eBike battery's state of charge. The state of charge of the eBike battery can also be checked on the LEDs of the battery itself. In the indicator (g), each bar in the battery symbol repres- ents approximately 20% capacity: The eBike battery is fully charged. The eBike battery should be recharged. The LEDs of the battery charge indicator on the battery go out. The capacity for assisting the drive has been used up, and assistance is gently switched off. The remaining capacity is made available for the lighting. The indicator flashes. The capacity of the eBike battery is enough for about two hours of lighting. If an eBike is powered by two batteries, the battery charge indicator(g) displays the state of charge of both batteries. Speed and distance indicators The speedometer(a) always displays the current speed. The display(i) always shows the last setting as standard. Re- peated medium-length presses of the button– will display the trip distanceTRIP, the total distanceTOTAL and the range of the batteryRANGE one after the other. (Briefly pressing the button– will decrease the assistance level.) To reset the trip distanceTRIP, select the trip distanceTRIP and simultaneously press and hold the buttons+ and–. The display will initially showRESET. If you continue to press both buttons, the trip distanceTRIP will be set to 0.

1 270 020 XBK | (24.11.2021) Bosch eBike Systems 98English – 3 Fitting Fitting and removing the on-board computer (see figureA) Fit the lower part of the Kiox into the holder(5) first and tilt it forward gently until you can feel that the on-board com- puter is firmly fixed in the magnetic holder. To remove the on-board computer, hold it by the top end and pull it towards you until it disengages from the magnetic holder. u Remove the on-board computer when you park the eBike. The on-board computer can be secured in place to prevent it from being removed from the holder. To do this, loosen the headset screw(16) until the Kiox holder can be swivelled sideways. Put the on-board computer in the holder. Screw the locking screw (M3 thread, 6mm long) from below into the thread provided in the on-board computer (using a longer screw may damage the on-board computer). Swivel the holder back into place and tighten the headset screw in accordance with the manufacturer's specifications. Operation Before initial commissioning The Kiox is supplied with a partially charged battery. Before using it for the first time, this battery must be charged for at least one hour via the USB port (see "Power supply of the on- board computer", pageEnglish – 3) or via the eBike sys- tem. The control unit should be attached such that the buttons are almost perpendicular to the handlebars. When using the on-board computer for the first time, the lan- guage selection page is displayed initially. You can then choose to have essential functions and indications explained via the <Intro to Kiox> menu item. The menu item can also be called up at a later time via <Settings>→ <Informa- tion>. Switching the on-board computer on/off To switch on and switch off the on-board computer, briefly press the on/off button(4). Selecting system settings Fit the on-board computer in the holder and proceed as fol- lows with the bicycle stationary: Go to the status page (use the <button(10) on the control unit to get to the first display) and call up the (9) <Settings> with the select button. You can use the –(11) and +(12) buttons to select the set- ting you want. You can open the settings, as well as any addi- tional submenus, using the select button(9). You can use the <button(10) to go back to the previous menu from any settings menu. The following settings can be changed in the <Sys set- tings>: – <Brightness> – <Time> – <Date> – <Time zone> – <24h format> – <Bright background> – <Imperial units> – <Language> – <Factory reset> Starting up the eBike system Requirements The eBike system can only be activated when the following requirements are met: – A sufficiently charged eBike battery is inserted (see oper- ating instructions for the battery). – The on-board computer is properly fitted to the holder. Switching the eBike system on/off The following options are available for switching on the eBike system: – Once the on-board computer and the eBike battery are fitted, briefly press the on/off button(4) on the on-board computer. – With the on-board computer inserted, push the on/off button on the eBike battery (bicycle manufacturer-spe- cific solutions are possible when there is no access to the battery on/off button; see the battery operating instruc- tions). The drive is activated as soon as you start pedalling (except if you are using the walk assistance function or if the assist- ance level is set to OFF). The motor output adjusts to the as- sistance level set. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25/45km/h, the eBike drive switches off the assistance. The drive is automat- ically reactivated as soon you start pedalling again and the speed is below 25/45km/h. The following options are available for switching off the eBike system: – Briefly press the on/off button (4) of the on-board com- puter. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). – Remove the on-board computer from its holder. If no power is drawn from the eBike drive for about10minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the con- trol unit of the eBike, the eBike system will switch off auto- matically. Power supply of the on-board computer If the on-board computer is in the holder(5), a sufficiently charged eBike battery is inserted into the eBike and the Bosch eBike Systems 1 270 020 XBK | (24.11.2021) 99English – 4 eBike system is switched on, then the on-board computer battery is powered and charged by the eBike battery. To charge the on-board computer battery, slide the on-board computer back onto the holder (5). Note that if you do not charge the eBike battery straight away, the eBike system will automatically switch off after 10 minutes of inactivity. If this happens, the on-board computer battery will also stop char- ging. You can also charge the on-board computer via the USB port(6). To do this, open the protective cap(17). Use a Mi- cro USB cable to connect the USB port on the on-board com- puter to a commercially available USB charger (not included with the product as standard) or to the USB port of a com- puter (max. 5V charging voltage; max. 1000mA charging current). If the on-board computer is removed from the holder (5), all values for the functions are saved and can still be scrolled through. After use, the USB port must be carefully resealed with the protective cap(17). If the Kiox battery is not recharged, the date and time will be retained for up to 6 months. When the on-board computer is switched on again, the date and time will be reset if a Bluetooth® connection to the app has been established and the smartphone has successfully identified the current loca- tion via GPS. Note: The Kiox only charges while it is switched on. Note: If the Kiox is switched off during charging via a USB cable, the Kiox can only be switched on again once the USB cable has been disconnected. Note: To maximise the lifespan of the on-board computer's battery, it should be recharged for one hour every three months. Battery Charge Indicator The battery charge indicator of the eBike batteryd (see "Start page", pageEnglish – 7) can be read on the status page and in the status bar. The eBike battery's state of charge is also indicated by the LEDs on the eBike battery it- self. Colour of the indicator Meaning Green The eBike battery is over 30% charged. Orange The eBike battery is between 15% and 30% charged. Red The eBike battery is between 0% and 15% charged. Red + ! The capacity for assisting the drive has been used up, and assistance is switched off. The remaining capacity will be provided for the bike Colour of the indicator Meaning lights and the on-board com- puter. If the eBike battery is being charged on the bike, a corres- ponding notification will be displayed. If the on-board computer is removed from the holder(5), the state of charge that was last displayed for the eBike bat- tery is saved. Storage mode/resetting the Kiox The on-board computer has an energy-saving storage mode which minimises the rate at which the internal battery dis- charges. Setting to this mode erases the date and time. This mode can only be activated by pressing and holding the on/off button(4) of the on-board computer for at least 8seconds. If the on-board computer does not start when the on/off but- ton(4) is pressed briefly, the on-board computer is in stor- age mode. You can deactivate storage mode by pressing the on/off but- ton(4) for at least 2seconds. The on-board computer detects whether it is in a fully func- tional condition. If you press and hold the on/off button(4) for at least 8seconds while in a fully functional condition, the on-board computer will go into storage mode. If, con- trary to expectations, the Kiox is not in a fully functional con- dition and cannot be operated, pressing and holding the on/ off button(4) (for at least 8seconds) will reset it. After be- ing reset, the on-board computer will restart automatically after approx.5seconds. If the Kiox does not restart, press the on/off button(4) for 2seconds. To reset the Kiox to its factory settings, select <Settings>→ <Sys settings>→ <Factory reset>. All user data will be lost. Setting the assistance level On the operating unit (7), you can set the level of assistance you want the eBike drive to provide you with while pedalling. The assistance level can be changed at any time, even while cycling. Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here. The following assistance levels are available as a maximum: – OFF: Motor assistance is switched off. The eBike can only be moved by pedalling, as with a normal bicycle. The walk assistance cannot be activated at this assistance level. – ECO: Effective assistance with maximum efficiency, for maximum range – TOUR/TOUR+: TOUR: Steady assistance, long range for touring TOUR+: Dynamic assistance for natural, sporty cycling (only in conjunction witheMTB) 1 270 020 XBK | (24.11.2021) Bosch eBike Systems If the on-board computer is removed from the holder(5), the power is supplied by the on-board computer battery. If the on-board computer battery's charge is running low, a warning message appears on the display. 100English – 5 – SPORT/eMTB: SPORT: Powerful assistance, for mountain biking and cycling in urban traffic eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dy- namics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX.

To decrease the assistance level, press the – (11) button. The requested motor output appears on the displayh (see "Start page", pageEnglish – 7). The maximum motor out- put depends on the selected assistance level. If the on-board computer is removed from the holder(5), the assistance level that was last displayed is saved. Switching the push assistance on/off The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6km/h. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. To activate the walk assistance, briefly press the WALK but- ton on your on-board computer. Once it is activated, press the + button within 10s and keep it held down. The eBike drive is now switched on. Note: The push assistance cannot be activated at assistance level OFF. The push assistance is switched off as soon as one of the following occurs: – You release the +button; – The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle); – The speed exceeds 6km/h. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Switching bicycle lights on/off On the model on which the lighting is powered by the eBike system, the front and rear lights can be switched on and off at the same time via the on-board computer using the bike light button(3). Check that your bike lights are working correctly before every use. With the light switched on, the lightingc indicator (see "Start page", pageEnglish – 7) appears in the status bar on the display. Switching the bike lights on and off has no effect on the backlighting of the display. Creating a user ID To be able to use all functions of the on-board computer, you must register online.

Operation Starting Operation Prerequisites The eBike system can only be activated when the following requirements are met: – A sufficiently charged battery is inserted (see battery op- erating instructions). – The speed sensor is connected properly (see drive unit operating instructions). Switching the eBike system on/off The following options are available for switching on the eBike system: – Press the on/off button (2) of the on-board computer with the eBike battery inserted. – Press the on/off button of the eBike battery (see battery operating instructions). The drive is activated as soon as you start pedalling (except if you are using the walk assistance function or if the assist- ance level is set to OFF). The motor output adjusts to the as- sistance level set. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25km/h, the eBike drive switches off the assistance. The drive is automatically reactivated as soon you start pedalling again and the speed is below 25km/h. The following options are available for switching off the eBike system: – Press the on/off button (2) of the on-board computer. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). The system shuts down after being switched off. This takes approximately 3seconds. It cannot be switched back on un- til shutdown has been completed. If the eBike is not moved for approx. 10 min and no button is pressed on the on-board computer, the eBike system switches off automatically in order to save energy. Note: Always switch off the eBike system when you park the eBike. Note: If the battery of the SmartphoneHub is empty, you can still switch on your eBike using the eBike battery. The Smart- phoneHub battery begins charging automatically once the 1 270 020 XBC | (11.02.2022) Bosch eBike Systems 152English – 3 eBike battery is switched on. Alternatively, the battery of the SmartphoneHub can be charged via the USB port. Linking the SmartphoneHub with a smartphone You can expand the indicators and functions of the Smart- phoneHub using the COBI.Bike smartphone app. This app can be downloaded free of charge from the AppStore (for Apple iPhones) or from the Google Play store (for Android devices). To connect your SmartphoneHub with the Smartphone, open the COBI.Bike app on your smartphone and follow the instructions in the app. Inserting a smartphone into the Universal Mount (seefiguresAandB) A Universal Mount(16) is supplied for attaching a smart- phone. Specific holders for iPhones can be purchased from the range of accessories. No separate power supply is ne- cessary for an iPhone holder. For the Universal Mount, the power (5V/1A, max.1.5A) is supplied using a separate USB cable (included with delivery) via the micro‑A/B USB port of the SmartphoneHub. The Universal Mount(16) can only hold Apple iPhones and Android smartphones (including a case) measuring between 7.1mm and 8.26mm in depth, between 123.8mm and 158.4mm in length, and between 58.6mm and 78.1mm in width. The maximum weight of the smartphone including case is 250g. u Please note that the manufacturer specifications do not always reflect the maximum dimensions. Some manufacturers do not account for the protruding camera in the depth measurement. The specified dimensions include any phone cases. Smart- phones with folio and carrying cases must not be used. u Be careful not to pinch your fingers between the retaining brackets and the smartphone when inserting your smart- phone. Once you have inserted your smartphone, check that the smartphone cannot come into contact with any hard parts on the bike even in case of vibrations, as this could cause last- ing damage to the smartphone. Inserting the Uni- versal Mount (seefigureA) Push the Universal Mount(16) onto the SmartphoneHub from the front until you hear it click into place➊. The Universal Mount can also be fixed in place using the two fastening screws(17). Inserting the smart- phone (seefigureB) – Pull the front retaining bracket(18) forwards➋. – Insert the smartphone with the long side of the phone positioned against the rear retaining bracket(19)➌. – Allow the front retaining bracket(18) to slide slowly to- wards the smartphone and release it➍. Power supply for the Smartphone (optional) The smartphone can be supplied with power (5V/1A) using a separate USB cable (included with delivery) via the micro-A/B USB port of the Smart- phoneHub. To do this, connect the smartphone to the USB port of the SmartphoneHub using the USB cable. Removing the smartphone Use both hands to push the smart- phone forwards along with the front retaining bracket until the smartphone can be removed from the Universal Mount. If necessary, remove the USB cable for the power supply. Software update If a software update is available for the SmartphoneHub, an indicator is shown in the smartphone app. Follow the in- structions in the app to perform the update. Recovering the SmartphoneHub A recovery operation should be carried out on the Smart- phoneHub if it is no longer functioning correctly. To do this, open the app on your smartphone and follow the instruc- tions. Power supply for the SmartphoneHub The SmartphoneHub has an internal lithium-ion polymer bat- tery (nominal/minimum 300mAh, 3.7V) that cannot be re- moved. The SmartphoneHub can be switched on via its on/off but- ton(2) or via the on/off button of the eBike battery. If the SmartphoneHub cannot be switched on, it must be charged via a USB cable for at least 30minutes. If you do not use your SmartphoneHub, recharge the Smart- phoneHub every three months. You can charge the Smart- phoneHub battery via its USB port with any power adaptor, smartphone charger, etc. Switching the push assistance on/off The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6km/h. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. To activate the push assistance, briefly press the WALK button on your operating unit. Once it is activated, press and hold the +button within three seconds. The eBike drive is now switched on. Note: The push assistance cannot be activated at assistance level OFF. The push assistance is switched off as soon as one of the following occurs: – You release the +button; Bosch eBike Systems 1 270 020 XBC | (11.02.2022) 153English – 4 – The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle); – The speed exceeds 6km/h. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Setting the assistance level On the operating unit (15), you can set the level of assist- ance you want the eBike drive to provide you with while ped- alling. The assistance level can be changed at any time, even while cycling. Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here. The following assistance levels are available as a maximum: – OFF: Motor assistance is switched off. The eBike can only be moved by pedalling, as with a normal bicycle. The walk assistance cannot be activated at this assistance level. – ECO: Effective assistance with maximum efficiency, for maximum range – TOUR/TOUR+: TOUR: Steady assistance, long range for touring TOUR+: Dynamic assistance for natural, sporty cycling (only in conjunction witheMTB) – SPORT/eMTB: SPORT: Powerful assistance, for mountain biking and cycling in urban traffic eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dy- namics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX.

Operation Starting up the eBike system Requirements The eBike system can only be activated when the following requirements are met: – A sufficiently charged eBike battery is inserted (see oper- ating instructions for the battery). – The on-board computer is properly fitted in the holder. – The on-board computer battery must be sufficiently charged. Switching the eBike system on/off The following options are available for switching on the eBike system: – Once the on-board computer and the eBike battery are fitted, briefly press the on/off button(3) on the on-board computer. – With the on-board computer inserted, press the on/off button on the eBike battery (bicycle manufacturer-spe- cific solutions are possible when there is no access to the battery on/off button; see the operating instructions from the bicycle manufacturer). The drive is activated as soon as you start pedalling (except if you are using the walk assistance function or if the assist- ance level is set to OFF). The motor output adjusts to the as- sistance level set. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25/45km/h, the eBike drive switches off the assistance. The drive is automat- ically reactivated as soon you start pedalling again and the speed is below 25/45km/h. The following options are available for switching off the eBike system: – Press and hold the on/off button(3) on the on-board computer for at least 3 seconds. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). Note: This puts theNyon (BUI350) into a standby mode. – Remove the on-board computer from its holder. If no power is drawn from the eBike drive for about10minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the con- trol unit of the eBike, the eBike system will switch off auto- matically. Nyon (BUI350) goes into standby mode as a result. Standby Mode You can put your on-board computer into a standby mode, which enables the on-board computer and system to start up more quickly. Standby mode can be activated as follows: – To do this, press the on/off button(3) on the on-board computer for at least 1second, but no longer than 3seconds. – Wait 10 minutes until the system switches off. – Switch the battery off using the on/off button on the bat- tery. Pressing the on/off button(3) on the on-board computer for at least 1second ends standby mode. Standby mode ends and the on-board computer automatic- ally switches off if the state of charge of the on-board com- puter's battery is less than 75%. In any case, the on-board computer switches off at midnight (00:00) at the latest. If Nyon (BUI350) cannot be switched on or does not work properly, press and hold the on/off button (for approx. 15seconds). This may correct the malfunction. Power supply of the on-board computer If the on-board computer is in the holder(4), a sufficiently charged eBike battery is inserted into the eBike and the eBike system is switched on, then the on-board computer battery is powered and charged by the eBike battery. If the on-board computer is removed from the holder(4), the power is supplied by the on-board computer battery. The state of charge of the on-board computer battery is dis- played in the top left corner of the status bar. If the on-board computer battery's charge is running low, a warning message appears on the display. To charge the on-board computer battery, slide the on-board computer back onto the holder (4). Note that if you do not charge the eBike battery straight away, the eBike system will automatically switch off after 10 minutes of inactivity. If this Bosch eBike Systems 1 270 020 BN2 | (01.12.2021) 199English – 4 happens, the on-board computer battery will also stop char- ging. You can also charge the on-board computer via the USB port(8). To do this, open the protective cap(2). Use a Micro USB cable to connect the USB port on the on-board com- puter to a commercially available USB charger (not included with the product as standard) or to the USB port of a com- puter (max. 5V charging voltage; max. 1500mA charging current). If the on-board computer's battery is not recharged, the date and time will be retained for approx. 6 months. Note: To maximise the lifespan of the on-board computer's battery, it should be recharged for one hour every three months. After use, the USB port must be carefully resealed with the protective cap(2). u USB connections are not waterproof. When cycling in the rain, do not connect any external devices and make sure that the USB port is fully sealed by the pro- tective cover(2). It is not possible to charge external devices via the USB port. Battery Charge Indicator The battery charge indicator for the eBike batteryg (see "<Ride Screen>", pageEnglish – 8) can be read on the status bar. The eBike battery's state of charge is also indic- ated by the LEDs on the eBike battery itself. Colour of the indicator Meaning Green The eBike battery is over 30% charged. Orange The eBike battery is between 15% and 30% charged. Red The eBike battery is between 0% and 15% charged. Red + ! The capacity for assisting the drive has been used up, and assistance is switched off. The remaining capacity will be provided for the bike lights and the on-board com- puter. If the eBike battery is being charged on the bike, a corres- ponding notification will be displayed. If the on-board computer is removed from the holder(4), the state of charge that was last displayed for the eBike bat- tery is saved. Initial operation of the on-board computer u Before first use, remove the protective film from the display in order to ensure the full functionality of the on-board computer. If the protective film remains on the display, this can impair the functionality/performance of the on-board computer. u The full functionality of the on-board computer cannot be guaranteed if the protective display film is used. Nyon is supplied with a partially charged battery. Before first use, the Nyon battery must be fully charged via the USB port or the eBike system.

When you switch on Nyon, it begins the satellite search to re- ceive GPS signals. When sufficient satellites have been found, the location point changes colour from grey to blue. In the case of unfavourable weather conditions or locations, the satellite search may take a little longer. If the application fails to find satellite signals over a prolonged period of time, restart Nyon. The first search for satellites may take a few minutes. To achieve the most accurate positioning, the first satellite search should be done outdoors. Ideally, stay stationary for a few minutes, even if the position has already be found. When Nyon has determined your location, this will be shown on the map. To increase the size of the map section, touch the touchscreen with two fingers and spread them out. To decrease the size of the map section, pinch both fingers to- gether. To move the map, simply move the map with both fingers on the screen. To select a destination, press and hold one finger on the map.

Failure to observe the safety in- formation and follow instructions may result in electric shock, fire and/or serious injury. Save all safety warnings and instructions for future ref- erence. The term battery is used in these instructions to mean all original Bosch eBike rechargeable battery packs. u Read and observe the safety warnings and directions contained in all the eBike system operating instruc- tions and in the operating instructions of your eBike. u Do not attempt to change – and especially increase – the power of your drive or the maximum speed that it supports. Doing this may put yourself and others at risk, and you may also breach statutory regulations. u Do not make any modifications to your eBike system or fit any other products that might increase the per- formance of your eBike system. Doing so will generally reduce the service life of the system and risks damaging the drive unit and the bike. You also run the risk of losing the guarantee and warranty claims on the bicycle you have purchased. By handling the system improperly you are also endangering your safety and that of other road users, thus running the risk of high personal liability costs and possibly even criminal prosecution in the event of ac- cidents that can be attributed to manipulation of the bi- cycle. u Do not open the drive unit yourself. The drive unit must only be repaired by qualified personnel using only original spare parts. This will ensure that the safety of the drive unit is maintained. Unauthorised opening of the drive unit will render warranty claims null and void. u All components fitted to the drive unit and all other components of the eBike drive (e.g. chainring, chain- ring receptacle, pedals) must only be replaced with identical components or components that have been specifically approved by the manufacturer for your eBike. This will protect the drive unit from overloading and becoming damaged. u Remove the battery from the eBike before beginning work (e.g. inspection, repair, assembly, maintenance, work on the chain, etc.) on the eBike, transporting it with a car or aeroplane, or storing it. Unintentional ac- tivation of the eBike system poses a risk of injury. u The eBike system can be activated by pushing the eBike backwards or by turning the pedals backwards. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. u When the push assistance is activated, the pedals may turn at the same time. When the push assistance func- tion is activated, make sure that there is enough space between your legs and the turning pedals to avoid the risk of injury. u When using the walk assistance, make sure that you can control the eBike and that you can hold it securely at all times. Under certain circumstances, the walk as- sistance may stop (e.g. if the pedals hit an obstacle or if you accidentally let go of the button on the operating unit). The eBike may suddenly move backwards onto you or tip up. This presents a risk for the user particularly if there is additional load on the eBike. When using the walk assistance, do not bring the eBike into situations in which you cannot hold the eBike using your own strength. On sections of the drive, temperatures >60°C may occur in extreme conditions, e.g. when carrying consistently high loads at low speed when riding up hills or transport- ing loads. u After a ride, do not allow your unprotected hands or legs to come into contact with the housing of the drive unit. Under extreme conditions, such as continuously high torques at low travel speeds, or when riding up hills or carrying loads, the housing may reach a very high tem- perature. The temperature that the drive unit housing may reach is influenced by the following factors: – Ambient temperature – Ride profile (route/gradient) – Ride duration – Assistance modes – User behaviour (personal effort) – Total weight (rider, eBike, luggage) – Motor cover on the drive unit – Heat dissipation properties of the bicycle frame – Type of drive unit and type of gear-shifting u Use only original Bosch batteries that the manufac- turer has approved for your eBike. Using other batter- ies can lead to injuries and pose a fire hazard. Bosch ac- cepts no liability or warranty claims if other batteries are used. u Observe all national regulations which set out the ap- proved use of eBikes.

Bulbs must only be replaced with bulbs of the same voltage. Inserting a bulb incorrectly can cause it to blow. Assembly Inserting and removing the battery For inserting and removing the eBike battery in/from the eBike, please read and observe the battery operating in- structions. Checking the speed sensor (see figure A) Speedsensor (standard) The speed sensor (2) and its spoke magnet (3) must be fit- ted such that the spoke magnet moves past the speed sensor at a distance of at least 5 mm and at most 17 mm with each rotation of the wheel. Note: If the distance between the speed sensor (2) and the spoke magnet (3) is too small or too large, or if the speed sensor (2) is not properly connected, the speedometer dis- play will fail and the eBike drive unit will operate in emer- gency mode. Should this occur, loosen the screw of the spoke magnet (3) and fasten the spoke magnet to the spoke such that it runs past the marking on the speed sensor at the correct clear- ance. If the speed is still not being indicated on the speedo- meter display after doing this, please contact an authorised bicycle dealer. When changing a wheel, make sure that the sensor cable is routed so that it is not under tension and has no kinks. Speedsensor (slim) The speedsensor (slim)(4) and its magnet(5) must be mounted in such a manner that the magnet, after a turn of 0 275 007 XD3 | (24.11.2021) Bosch eBike Systems 266English – 3 the wheel, moves past the speed sensor with a clearance of at least 2 mm, yet no more than 8 mm. If any structural changes are made, the correct distance between the magnet and the sensor must be complied with (see figureA). Note: Make sure you do not damage the sensor or the sensor holder when fitting or removing the rear wheel. When changing a wheel, make sure that the sensor cable is routed so that it is not under tension and has no kinks. The CenterLock magnet(5) can only be removed and rein- serted up to five times. Operation Start-up Requirements The eBike system can only be activated when the following requirements are met: – A sufficiently charged battery is inserted (see battery op- erating instructions). – The on-board computer is properly inserted in the holder (see on-board computer operating instructions). – The speed sensor is correctly connected (see "Checking the speed sensor (see figure A)", pageEnglish – 2). Switching the eBike system on/off The following options are available for switching on the eBike system: – If the on-board computer is already switched on when you insert it into the holder, the eBike system will be activated automatically. – Once the on-board computer and the eBike battery are fitted, briefly press the on/off button on the on-board computer. – With the on-board computer inserted, push the on/off button on the eBike battery (bicycle manufacturer-spe- cific solutions are possible when there is no access to the battery on/off button; see the battery operating instruc- tions). The drive is activated as soon as you start pedalling (except if you are using the push-assistance function, Switching the push assistance on/off). The motor output depends on the settings of the assistance level on the on-board computer. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25km/h, the eBike drive switches off the assistance. The drive is automatically reactivated as soon you start pedalling again and the speed is below 25km/h. The following options are available for switching off the eBike system: – Press the on/off button of the on-board computer. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). – Remove the on-board computer from its holder. If the eBike is not moved for approx. 10 min and no button is pressed on the on-board computer, the eBike system switches off automatically in order to save energy. eShift (optional) eShift is the integration of electronic gear-shifting systems into the eBike system. The eShift components are electric- ally connected to the drive unit by the manufacturer. The separate operating instructions describe how to operate the electronic gear-shifting systems. Setting the assistance level You can set the level at which the eBike drive assists you while pedalling on the on-board computer. The assistance level can be changed at any time, even while cycling. Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here. The following assistance levels are available as a maximum: – OFF: Motor assistance is switched off. The eBike can only be moved by pedalling, as with a normal bicycle. The walk assistance cannot be activated at this assistance level. – ECO: Effective assistance with maximum efficiency, for maximum range – TOUR/TOUR+: TOUR: Steady assistance, long range for touring TOUR+: Dynamic assistance for natural, sporty cycling (only in conjunction witheMTB) – SPORT/eMTB: SPORT: Powerful assistance, for mountain biking and cycling in urban traffic eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dy- namics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX. A software update may be required.) – TURBO: Maximum assistance even at a high cadence, for sporty cycling The requested motor output appears on the display of the on-board computer. The maximum motor output depends on the selected assistance level. Bosch eBike Systems 0 275 007 XD3 | (24.11.2021) 267English – 4 Assistance level Assistance factor

The assistance factor may vary in some models.

The assistance level between TOUR and TURBO mode is dynamically progressive Switching the push assistance on/off The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6km/h. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. To activate the walk assistance, briefly press the WALK but- ton on your on-board computer. Once it is activated, press the + button within 10s and keep it held down. The eBike drive is now switched on. Note: The push assistance cannot be activated at assistance level OFF. The push assistance is switched off as soon as one of the following occurs: – You release the +button; – The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle); – The speed exceeds 6km/h. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Switching bicycle lights on/off On the model where the bike lights are powered by the eBike system, the front light and taillight can be switched on and off at the same time via the on-board computer. Check that your bike lights are working correctly before every use. Notes on cycling with the eBike system When does the eBike drive work? The eBike drive assists your cycling only when you are ped- alling. If you do not pedal, the assistance will not work. The motor output always depends on the pedalling force you ap- ply. If you apply less force, you will receive less assistance than if you apply a lot of force. This applies irrespective of the as- sistance level. The eBike drive automatically switches off at speeds over 25km/h. When the speed falls below 25km/h, the drive automatically becomes available again. An exception applies to the push assistance function, in which the eBike can be pushed at low speed without ped- alling. The pedals may rotate when the push assistance is in use. You can also use the eBike as a normal bicycle without as- sistance at any time, either by switching off the eBike system or by setting the assistance level to OFF. The same applies when the battery is drained. Interaction between the eBike system and gear-shifting The gear-shifting should be used with an eBike drive in the same way as with a normal bicycle (observe the operating in- structions of your eBike on this point). Irrespective of the type of gear-shifting, it is advisable to briefly stop pedalling when changing gear. This will facilitate the gear change and reduce wear on the powertrain. By selecting the correct gear, you can increase your speed and range while applying the same amount of force. Gaining initial experience We recommend that you gain initial experience with the eBike away from busy roads. Test the various assistance levels, beginning with the lowest level. As soon as you feel confident, you can ride your eBike in traffic like any other bicycle. Test the range of your eBike in different conditions before planning longer and more demanding trips. Influences on range The range is affected by a number of factors, such as: – Assistance level – Speed – Gear shifting behaviour – Tyre type and tyre pressure – Age and condition of the battery – Route profile (gradients) and conditions (road surface) – Headwind and ambient temperature – Weight of eBike, rider and luggage For this reason, it is not possible to predict the range accur- ately before and during a trip. However, as a general rule: – With the same assistance level on the eBike drive: The less energy you need to exert in order to reach a certain speed (e.g. by changing gears optimally), the less energy the eBike drive will consume and the higher the range per battery charge will be. – The higher the selected assistance level under otherwise constant conditions, the smaller the range will be. 0 275 007 XD3 | (24.11.2021) Bosch eBike Systems 268English – 5 Taking care of your eBike Please observe the operating and storage temperatures of the eBike components. Protect the drive unit, on-board com- puter and battery against extreme temperatures (e.g. from intense sunlight without adequate ventilation). Extreme tem- peratures can cause the components (especially the battery) to become damaged. Have your eBike system checked by an expert at least once a year (including mechanical parts, up-to-dateness of system software). Maintenance and servicing Maintenance and cleaning When changing the bulbs, ensure that they are compatible with the Bosch eBike system (ask your bicycle dealer) and are suitable for the specified voltage. Bulbs must only be re- placed with bulbs of the same voltage. Do not immerse any components, including the drive unit, in water or clean them with pressurised water.

The motor output depends on the settings of the assistance level on the on-board computer. As soon as you stop pedalling when in normal operation, or as soon as you have reached a speed of 25/45km/h, the eBike drive switches off the assistance. The drive is automat- ically reactivated as soon you start pedalling again and the speed is below 25/45km/h. The following options are available for switching off the eBike system: – Press the on/off button of the on-board computer. – Switch off the eBike battery using its on/off button (bi- cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi- cycle manufacturer operating instructions). – Remove the on-board computer from its holder. If the eBike is not moved for approx. 10 min and no button is pressed on the on-board computer, the eBike system switches off automatically in order to save energy. eShift (optional) eShift is the integration of electronic gear-shifting systems into the eBike system. The eShift components are electric- ally connected to the drive unit by the manufacturer. The separate operating instructions describe how to operate the electronic gear-shifting systems. Setting the assistance level You can set the level at which the eBike drive assists you while pedalling on the on-board computer. The assistance level can be changed at any time, even while cycling. Note: In some models, the assistance level may be preset and cannot be changed. There may also be fewer assistance levels available than stated here. The following assistance levels are available as a maximum: – OFF: Motor assistance is switched off. The eBike can only be moved by pedalling, as with a normal bicycle. The walk assistance cannot be activated at this assistance level. – ECO: Effective assistance with maximum efficiency, for maximum range – TOUR/TOUR+: TOUR: Steady assistance, long range for touring TOUR+: Dynamic assistance for natural, sporty cycling (only in conjunction witheMTB) – SPORT/eMTB: SPORT: Powerful assistance, for mountain biking and cycling in urban traffic eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dy- namics and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX and BDU480 CX. A software update may be required.) – TURBO: Maximum assistance even at a high cadence, for sporty cycling The requested motor output appears on the display of the on-board computer. The maximum motor output depends on the selected assistance level. Bosch eBike Systems 0 275 007 XD4 | (25.11.2021) 293English – 4 Assistance level Assistance factor

The assistance factor may vary in some models.

Maximum value Switching the push assistance on/off The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 6km/h. u The push assistance function must only be used when pushing the eBike. There is a risk of injury if the wheels of the eBike are not in contact with the ground while using the push assistance. To activate the walk assistance, briefly press the WALK but- ton on your on-board computer. Once it is activated, press the + button within 10s and keep it held down. The eBike drive is now switched on. Note: The push assistance cannot be activated at assistance level OFF. The push assistance is switched off as soon as one of the following occurs: – You release the +button; – The wheels of the eBike are locked (e.g. by applying the brakes or hitting an obstacle); – The speed exceeds 6km/h. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely. Switching bicycle lights on/off On the model where the bike lights are powered by the eBike system, the front light and taillight can be switched on and off at the same time via the on-board computer. Check that your bike lights are working correctly before every use. Notes on cycling with the eBike system When does the eBike drive work? The eBike drive assists your cycling only when you are ped- alling. If you do not pedal, the assistance will not work. The motor output always depends on the pedalling force you ap- ply. If you apply less force, you will receive less assistance than if you apply a lot of force. This applies irrespective of the as- sistance level. The eBike drive automatically switches off at speeds over 25/45km/h. When the speed falls below 25/45km/h, the drive automatically becomes available again. An exception applies to the push assistance function, in which the eBike can be pushed at low speed without ped- alling. The pedals may rotate when the push assistance is in use. You can also use the eBike as a normal bicycle without as- sistance at any time, either by switching off the eBike system or by setting the assistance level to OFF. The same applies when the battery is drained. Interaction between the eBike system and gear-shifting The gear-shifting should be used with an eBike drive in the same way as with a normal bicycle (observe the operating in- structions of your eBike on this point). Irrespective of the type of gear-shifting, it is advisable to briefly stop pedalling when changing gear. This will facilitate the gear change and reduce wear on the powertrain. By selecting the correct gear, you can increase your speed and range while applying the same amount of force. Gaining initial experience We recommend that you gain initial experience with the eBike away from busy roads. Test the various assistance levels, beginning with the lowest level. As soon as you feel confident, you can ride your eBike in traffic like any other bicycle. Test the range of your eBike in different conditions before planning longer and more demanding trips. Influences on range The range is affected by a number of factors, such as: – Assistance level – Speed – Gear shifting behaviour – Tyre type and tyre pressure – Age and condition of the battery – Route profile (gradients) and conditions (road surface) – Headwind and ambient temperature – Weight of eBike, rider and luggage For this reason, it is not possible to predict the range accur- ately before and during a trip. However, as a general rule: – With the same assistance level on the eBike drive: The less energy you need to exert in order to reach a certain speed (e.g. by changing gears optimally), the less energy the eBike drive will consume and the higher the range per battery charge will be. – The higher the selected assistance level under otherwise constant conditions, the smaller the range will be. 0 275 007 XD4 | (25.11.2021) Bosch eBike Systems 294English – 5 Taking care of your eBike Please observe the operating and storage temperatures of the eBike components.

To do this, press the on/off button (4) to switch the battery on. If none of the LEDs on the battery charge indicator (3) light up, the battery may be damaged. If at least one (but not all) of the LEDs on the battery charge indicator (3) lights up, the battery will need to be fully charged before using it for the first time. 0 275 007 XPX | (11.03.2022) Bosch eBike Systems 322English – 3 u Do not charge or use batteries if they are damaged. Contact an authorised bicycle dealer. Charging the battery u A Bosch eBike battery must only be charged using an original Bosch eBike charger. Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using it for the first time. To charge the battery, read and follow the instructions in the operating manual for the charger. The battery can be charged at any state of charge. Interrupt- ing the charging process does not damage the battery. The battery has a temperature monitoring function which only allows it to be charged within a temperature range of 0°C to 40°C. If the temperature of the bat- tery is outside this charging range, three of the LEDs on the battery charge indicator (3) will flash. Disconnect the battery from the charger and let it acclimatise. Do not reconnect the battery to the charger until it has reached the correct charging temperature. Battery charge indicator The five LEDs on the battery charge indicator(3) indicate the battery's state of charge when the battery is switched on. Each LED represents approximately 20% of the charging ca- pacity. When the battery is fully charged, all five LEDs will be lit. The battery's state of charge when switched on is also shown on the display of the on-board computer. Read and follow the instructions in the operating manuals for the drive unit and on-board computer. If the battery capacity is less than 10%, the last remaining LED will flash. If the battery capacity is less than 5%, all the LEDs on the battery charge indicator (3) on the battery will go out. The display function of the on-board computer, however, will carry on working. Once charging is complete, disconnect the battery from the charger and the charger from the mains. Using two batteries for one eBike (optional) The manufacturer can also equip an eBike with two batter- ies. In this case, one of the charging sockets will not be ac- cessible or it will have been sealed with a sealing cap by the bicycle manufacturer. Only charge the batteries via the char- ging socket that is accessible. u Never open charging sockets that have been sealed by the manufacturer. Charging batteries via a charging socket that used to be sealed may cause irreparable dam- age. If you want to use an eBike that is designed for two batteries with only one battery, cover the contacts of the unused socket using the cover (10) provided. Otherwise there is a risk that the exposed contacts will cause a short circuit (see figures A and B). Charging process for two batteries If two batteries are fitted to an eBike, both batteries can be charged using the uncovered connection. To begin with, both batteries are charged one after the other until they reach approx.80–90% capacity, then they are both fully charged at the same time (the LEDs flash on both batteries). When the bike is in operation, power is drawn from both bat- teries on an alternating basis. If you take the batteries out of the holders, you can charge each one individually. Charging with one battery fitted If only one battery is fitted, you can only charge the battery that has the accessible charging socket on the bike. You can only charge the battery with the sealed charging socket if you take the battery out of the holder. Inserting and removing the battery u Always switch off the battery and the eBike system when inserting the battery into the holder or remov- ing it from the holder. Inserting and removing the standard battery (see figure

In order for the battery to be inserted, the key (5) must be inserted into the lock (6) and the lock must be open.

The battery will be unlocked completely and fall into your hand. Pull the battery out of the frame. Note: As a result of varying designs, the battery may need to be inserted and removed using a different method. Read the operating instructions of the eBike manufacturer. Inserting the PowerTube battery (pivot) (seefigureD) In order for the battery to be inserted, the key (5) must be inserted into the lock (6) and the lock must be open.

To insert the PowerTube battery (15), place it so that its contacts are in the lower holder of the frame. ❷ Push the battery upwards until it is held by the safety restraint (14). ❸ Hold the lock open with the key and press the battery upwards until you hear it click into place. Check that the battery is secure in all directions.

Always secure the battery by closing the lock (6) – otherwise the lock may open and the battery may fall out of the holder. Always remove the key (5) from the lock (6) after locking it. This prevents both the key from falling out and the battery from being removed by unauthorised third parties when the eBike is not in use. Operation Start-up u Use only original Bosch batteries that the manufac- turer has approved for your eBike. Using other batter- ies can lead to injuries and pose a fire hazard. Bosch ac- cepts no liability or warranty claims if other batteries are used. Switching on/off Switching on the battery is one way to switch on the eBike system. Read and follow the instructions in the operating manuals for the drive unit and on-board computer. Before switching on the battery, i.e. the eBike system, make sure that the lock (6) is closed. To switch on the battery, press the on/off button (4). Do not use any sharp or pointed objects to press the button. The LEDs on the indicator (3) will light up, indicating the bat- tery's state of charge at the same time. Note: If the battery capacity is less than 5%, none of the LEDs on the battery charge indicator(3) will light up. Whether the eBike system is switched on is only visible on the on-board computer/control unit. To switch off the battery, press the on/off button (4) again. The LEDs on the indicator (3) will go out. This will also switch the eBike system off. If no power is drawn from the eBike drive for about10minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the con- trol unit of the eBike, the eBike system will switch off auto- matically. The battery is protected against deep discharge, overload- ing, overheating and short-circuiting by the "Electronic Cell Protection (ECP)". In the event of danger, a protective cir- cuit switches the battery off automatically. If a fault is detected in the battery, two of the LEDs on the battery charge indicator (3) will flash. Contact an au- thorised bicycle dealer if this happens. Recommendations for optimal handling of the battery The service life of the battery can be extended if it is looked after well and especially if it is stored at the correct temper- ature. As it ages, however, the capacity of the battery will diminish, even with good care. A significantly reduced operating time after charging indic- ates that the battery has deteriorated. The battery should be replaced. Recharging the battery before and during storage When you are not going to use the battery for an extended period (longer than three months), store it at a state of charge of around 30% to 60% (when two to three of the LEDs on the battery charge indicator (3) are lit). Check the state of charge after six months. If only one of the LEDs on the battery charge indicator (3) is lit, charge the battery back up to around 30% to 60%. Note: If the battery is stored with no charge for an extended period of time, it may become damaged despite the low self- discharge and the battery capacity could be significantly re- duced. Leaving the battery permanently connected to the charger is not recommended. Storage conditions If possible, store the battery in a dry, well-ventilated place. Protect it against moisture and water. When the weather conditions are bad, it is advisable to remove the battery from the eBike and store it in a closed room until you use it next, for example. Store the eBike batteries in the following locations: – In a room with a smoke alarm – Away from combustible or easily flammable objects – Away from heat sources 0 275 007 XPX | (11.03.2022) Bosch eBike Systems 324English – 5 To ensure an optimum service life, store the eBike batteries at temperatures between10°C and20°C. Never store them at temperatures below–10°C or above60°C. Make sure that the maximum storage temperature is not ex- ceeded. Do not leave the battery in your car in the summer, for example, and store it away from direct sunlight. Leaving the battery on the bicycle for storage is not recom- mended. Action in the event of a fault The Bosch eBike rechargeable battery must not be opened, including for repairs. There is a risk of the Bosch eBike re- chargeable battery catching fire, e.g. as a result of a short circuit. This risk continues to apply on any Bosch eBike re- chargeable battery ever opened, even at a later point in time. In the event of a fault, do not have your Bosch eBike re- chargeable battery repaired; instead, have it replaced with an original Bosch eBike rechargeable battery by your spe- cialist retailer. Maintenance and servicing Maintenance and cleaning u The battery must not be submerged in water or cleaned using a jet of water. Keep the battery clean and avoid contact with skincare products and insect repellant.Clean it carefully with a soft, damp cloth. Clean and lightly grease the connector pins occasionally.

Charging process for two batteries If two batteries are fitted to an eBike, both batteries can be charged using the uncovered connection. To begin with, both batteries are charged one after the other until they reach approx.80–90% capacity, then they are both fully charged at the same time (the LEDs flash on both batteries). When the bike is in operation, power is drawn from both bat- teries on an alternating basis. If you take the batteries out of the holders, you can charge each one individually. Charging process The charging process begins as soon as the charger is con- nected to the battery or charging socket on the bike and to the mains. Note: The charging process is only possible when the tem- perature of the eBike battery is within the permitted char- ging temperature range. Note: The drive unit is deactivated during the charging pro- cess. The battery can be charged with and without the on-board computer. When charging without the on-board computer, the charging procedure can be observed on the battery charge indicator. When the on-board computer is connected, a charging noti- fication appears on the display. 0 275 007 XCX | (20.01.2022) Bosch eBike Systems 354English – 3 The state of charge is displayed by the battery charge indic- ator(9) on the battery and by the bars on the on-board com- puter. The LEDs on the battery charge indicator(9) flash during the charging process. Each solid illuminated LED represents ap- proximately 20% of the charging capacity. The flashing LED indicates the next 20% currently charging. Once the eBike battery is fully charged, the LEDs go out im- mediately and the on-board computer is switched off. The charging process is terminated. The state of charge can be displayed for3 seconds by pressing the on/off button(10) on the eBike battery. Disconnect the charger from the mains and the battery from the charger. When the battery is disconnected from the charger, the bat- tery is automatically switched off. Note: If you have charged the battery on the bike, carefully close the charging socket (6) with the cover (7) after char- ging, so that no dirt or water can get in. If the charger is not disconnected from the battery after charging, after a few hours the charger will switch itself back on, check the state of charge of the battery and begin the charging procedure again if necessary. Errors – causes and corrective measures Cause Corrective measures Battery defective Two LEDs flash on the battery. Contact an authorised bike dealership.
