The Assisted Pedalling

This electric bicycle is equipped with an "assisted pedalling system", consisting of a motor, a battery and a speed sensor. It is important to know that when the system is on, the engine undertakes to supply energy only while you are pedalling. When you stop pedalling, the motor switches off and the electrical assistance for pedalling is missing.

In all pedal-assisted bicycles the engine switches off and the electrical assistance stops when the maximum speed allowed for electric bicycles of 25 km/h is reached.

When the speed drops below this value, the electrical assistance starts again until you stop pedalling.

How to start an E-bike

ON/OFF

Switch on e-bike by long pressing the power button on the display to activate.

The motor offers five assist modes: 0-5. Short press Up (+) or Down (-) to switch the pedal assist level. The display interface is shown in the figure. Start pedaling to activate pedal assistance.

We recommend that you start slowly and gradually increase your pedaling speed.

Walk Assist

Pressing and holding the DOWN button for 3 seconds activates Walk-Assist Mode. The e-bike will go at a speed of 5 km/h automatically.

Display functions:

Through the display you turn the bicycle on and off, adjust the pedaling assistance, and view the following information:

1. Plus Key or Minus/Walk Key to switch assist levels. To turn on/off integrated lights, press the "plus" button for more than 2 seconds.
2. Battery level.
3. ODO (total range), Trip (single trip range), TIME (riding time). Short press the M button to change options.
4. Current speed.
5. Error codes.
6. PAS level: There are 5 levels by default: 0/1/2/3/4/5. 0 means no assist power.
7. ON/OFF Key: Pressing changes the information on the display: TRIP/RIDE TIME/Power/Mileage.

• Power button – Turns the bicycle ON and OFF with a press of more than 3 seconds. (The display auto shuts off after a few minutes.) • + & - button - Selects pedal assistance.

The suspension lockout allows the front suspension to be locked for improved efficiency when climbing inclines. To activate or deactivate the lockout, turn the control knob to the desired position.

NOTES: Adjusting the rear suspension requires specialized tools. We do not recommend attempting this adjustment on your own.

Battery & Charger maintenance

LITHIUM BATTERY

At the end of each use of the bicycle or if the battery is flat, recharge the battery.

After prolonged use, the battery capacity will slowly decrease.

The average life of the battery depends on personal use and storage conditions. Even with proper maintenance, rechargeable batteries are not eternal. On average, a lithium battery remains active for about 500 charging cycles. It should be considered, however, that with each recharge the "capacity" of the battery drops proportionally. Even partial recharges (for example, a 1-hour recharge) are to be considered, for the purpose of the

number of possible cycles, as a complete recharge. Periodically fully discharge the battery and recharge it.

If the bicycle is not used for a long period, do not leave the battery connected to the charger for more than 8 hours. Leave it to charge for about 4 hours. In this case, do not pay attention to the battery charger lights.

When the battery is completely discharged, it must be immediately recharged. Do not leave the battery discharged and unused; immediately proceed with a recharge cycle. In this case, provide for a longer charging cycle of about 6 hours to allow complete activation of the battery.

It is recommended to use the bicycle once or twice a year until the battery is completely discharged. Then fully charge it. This process has a beneficial effect on battery life.

Battery capacity on the display

When you turn on the bicycle engine and start pedalling, the battery icon on the display indicates the instantaneous charge measured and not the actual charge availability.

In case of uphill routes, when the engine is more stressed, the indicator may show a reduced residual charge (the number of LEDs lit on the display decreases). When the motor is stopped, in case of a stop or advance by inertia (for example, downhill), the indicator may show a higher available charge (in the absence of load on the engine, the battery voltage increases).

The best time, therefore, to achieve the amount of residual charge is when reaching a constant speed and on a flat and straight path after stabilizing the work of the battery.

Battery charging

Recharge the battery without removing it from the frame.

At the end of each use of the bicycle, we do consider it worthwhile to always recharge the battery. Keeping the battery charged at all times extends its life.

It is compulsory to use the battery charger supplied and follow the instructions on it. Do not use battery chargers not approved by SHARP. They may damage the battery and limit its life. By using personal accessories not supplied with the bicycle, the legal guarantee will automatically expire.

Before charging the battery, carefully read the following instructions and follow them during the process.

• Use only the supplied battery charger.
• Keep both the battery charger and the battery away from children and pets.
• The charging operation must be carried out in a spacious, cool and dry place; away from direct heat sources and humidity.
• If the charging operation takes place with the battery housed in the bicycle, make sure that it is stable on the stand and turned off.

- It is normal for the battery charger to heat up during charging.

- Do not cover the battery charger.

- Keep the plugs always clean and dry.

- Do not get the battery charger wet.

- Do not use the battery charger and/or the battery if they are damaged.

- Always connect the battery charger to the battery first and then to the power socket.

- Do not carry out the charging process in direct sunlight.

- Do not use the battery charger for other purposes or for other devices.

• Voltage drops during charging cycles could damage the battery.

Do not leave the battery connected to the charger for more than 8 hours. If the temperature of the battery rises too high, an unpleasant smell will be felt: stop charging immediately and contact the Service Centre.

Battery FAQs

Is it normal for the battery to get warm during charging?

Yes, it is normal for the battery to be warm during the charging process.
