Operation

Initial Operation

Requirements

The eBike system can only be activated when the following requirements are met:

• A sufficiently charged battery pack is inserted (see battery pack operating instructions).
• The speed sensor is connected properly (see drive unit operating instructions).

Switching the eBike System On/Off

Options for switching on the eBike system:

• Press the On/Off button 1 of the on-board computer with the eBike battery pack inserted.
• Press the On/Off button of the eBike battery pack (see battery pack operating instructions).

The drive is activated as soon as you step on the pedals (except for in the push assistance function or in assistance level "OFF"). The motor output depends on the settings of the assistance level on the on-board computer.

As soon as you stop pedaling when in normal operation, or as soon as you have reached a speed of 25/45 km/h, the assistance from the eBike drive is switched off. The drive is automatically re-activated as soon you start pedaling again and the speed is below 25/45 km/h.

Options 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 (bicycle manufacturer-specific solutions are possible whereby there is no access to the battery On/Off button; see the bicycle manufacturer operating instructions).

The system shuts down after being switched off; this takes approximately 3 seconds. It cannot be switched back on immediately until shutdown has been completed.

If the eBike is not moved and no button is pressed on the onboard computer for 10 minutes, the eBike system will shut down 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 pack. It is, however, recommended that you replace the internal batteries as soon as possible in order to avoid damage.

Displays and configurations of the on-board computer

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 2.5 seconds)

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 unscrewing the fastening screw 3 of the on-board computer. Open the battery lid 10 using a suitable coin, remove the used batteries and insert new CR 2016 batteries. You can obtain the batteries recommended by Bosch from your bicycle dealer.

When inserting batteries, pay attention to the correct polarity.

Close the battery compartment again and fasten the on-board computer to your eBike's handlebars using the fastening screw 3.

Battery Charge-control Indicator

The battery charge-control indicator g displays the charge level of the eBike battery pack. The charge level of the eBike battery pack can also be checked on the LEDs of the battery pack itself.

On indicator g, each bar of the battery pack symbol is equivalent to a capacity of approx. 20 %:

The eBike battery pack is fully charged.

The eBike battery pack should be recharged.

The LEDs of the charge-control indicator on the battery extinguish. 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 pack is enough for about 2 hours of lighting.

Switching the Push-assistance mode On/Off

The push-assistance feature makes it easier to push the eBike. The speed in this function depends on the set gear and cannot exceed 6 km/h (max.). The lower the set gear, the lower the speed in the push-assistance function (at full output).

The push-assistance function may only be used when pushing the eBike. Danger of injury when the wheels of the eBike do not have ground contact while using the push-assistance function.

To activate the push-assistance function, short-press the button "WALK" on your on-board computer. After activation, press button "+" within 3 s and keep it pressed. The eBike drive is switched on.

Note: The push assistance cannot be activated in the "OFF" assistance level.

The push assistance is switched off as soon as one of the following occurs:

• You release the "+" 6 button;
• The wheels of the eBike are prevented from turning (e.g. by braking or being hit by your leg);
• The speed exceeds 6 km/h.

Note: On some systems the push-assistance function can be started directly by pressing the "WALK" button.

Setting the Assistance Level

On the on-board computer you can set how much the eBike drive assists you while pedalling. The assistance level can be changed at any time, even while cycling.

Note: For individual versions, it is possible that the assistance level is pre-set and cannot be changed. It is also possible that less assistance levels are available for selection than listed here.

When the eBike is configured in “eMTB Mode” by the manufacturer, the assistance level “SPORT” is replaced by “eMTB”. In “eMTB Mode”, the assistance factor and torque are dynamically adjusted as a function of the force you exert on the pedals. “eMTB Mode” is only available for Performance Line CX drives.

The following assistance levels (max.) are available:

• “OFF”: The motor assistance is switched off, and the eBike can be moved as a normal bicycle only by pedalling. The push assistance cannot be activated in this assistance level.
• “ECO”: Effective assistance at maximum efficiency for maximum cruising range
• “TOUR”: Uniform assistance, for touring with long cruising range
• "SPORT"/"eMTB":

"SPORT": Powerful assistance for sportive riding off road as well as for urban traffic

“eMTB”: Optimal assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics and top performance.

- “TURBO”: Maximum assistance, supporting highest cadence for sportive riding

To increase the assistance level, short-press the button “+”6 on the on-board computer repeatedly until the required assistance level appears in indicator i. To decrease the assistance level, short-press the button “−”5.

Switching bike lights on/off

In the version which has the bike lights powered by the eBike system, medium-press the button “+” to switch on the front and rear lights at the same time. To switch off the bike lights, long-press the button “+”.

The lighting symbol h is displayed when the light is on.

Switching the bike light on and off has no effect on the back lighting of the display.

Displays and configurations of the on-board computer

Speed and Distance Indication

The speed indication a always displays the current speed.

Indicator i always displays the last setting as standard. Repeatedly medium-press 🏠 the button “–” to display the trip distance “TRIP”, the total distance “TOTAL” and the range of the battery pack “RANGE” one after the other. (Short-pressing 🏠 the button “–” will decrease the assistance level!)

The trip distance “TRIP” is reset by simultaneously long-pressing ⏻ the buttons “+” and “-”. The display will initially show “RESET”. If you continue to press both buttons, the trip distance “TRIP” will be set to “0”.

You can switch the displayed values from kilometres to miles by holding down button “-” and briefly pressing the On/Off button 1.

The versions of the subsystems can be displayed for the purposes of servicing. With the system switched off, simultaneously press buttons “−” and “+” and then press the On/Off button 1.

The USB socket is reserved for connecting diagnostic systems. The USB socket does not have any other function.

The USB connection must always be completely sealed with the protective cap 8.
