Risk of fines and confiscation!
Before riding the bike, make sure the bike aligns with the standards of your local law.
Reflectors are not a substitute for required lights. Riding at dawn, at dusk, at night or at other times of poor visibility without an adequate bicycle lighting system and without reflectors is dangerous and may result in serious injury or death.
If your bicycle does not fit properly, you may lose control and fall. Bolts that are too tight can stretch and deform.
Do not expose your battery to high temperatures.
Riding with improperly adjusted brakes or worn brake pads is dangerous and can result in serious injury or death.
Never inflate a tire beyond the maximum pressure marked on the tire's sidewall or the wheel rim. If the maximum pressure rating for the wheel rim is lower than the maximum pressure shown on the tire, always use the lower rating. Exceeding the recommended maximum pressure may blow the tire off the rim or damage the wheel rim, which could cause damage to the bike and injury to the rider and bystanders. The best and safest way to inflate a bicycle tire to the correct pressure is with a bicycle pump which has a built-in pressure gauge.
Applying brakes too hard or too suddenly can lock up a wheel, which could cause you to lose control and fall. Sudden or excessive application of the front brake may pitch the rider over the handlebars, which may result in serious injury or death.
Stop the charging procedure immediately if you notice a strange smell or smoke.

Pumping a bicycle tire
To pump your tires, you will need:
Bicycle pump with Presta valve compatibility
or
Presta valve adapter (if your pump does not have a built-in Presta valve head) not included.
How to pump a tire
a. If your pump has a dual head (fits both Presta and Schrader valves), make sure it's set up for Presta valves. If your pump is not Presta-compatible, you'll need a Presta valve adapter. Attach the adapter to the pump head. b. On the bicycle, unscrew the small nut at the top of the Presta valve by turning it anti-clockwise. This allows the valve to open and allows air to flow into the tire. c. Press down on the Presta valve to release a small amount of air. This helps ensure that the valve is not stuck and allows the pump to engage properly. d. Press your pump onto the Presta valve as far as you can. e. If your pump has a lever, flip it down to secure the pump head onto the Presta valve. This creates an airtight seal. f. Begin pumping air into the tire. g. Once you've reached the desired tire pressure, disconnect the pump head by releasing the lever or unscrewing it. h. Screw the small nut at the top of the Presta valve clockwise to close it.

- Lift the bike and turn the front or rear wheel. Check whether the front or rear wheel swings sideways or outwards.
- If the front or rear wheel swings sideways or outwards, have a professional check the wheel.
- Check the front and rear rims for cracks, deformation, or color changes at regular intervals.
- Check whether the rim is under the inner tube and the rim tape.
- Do not use the bike if the rim is cracked, deformed, or discolored.
- Have a professional check whether there is any damage on the rim, materials, or aluminum.
- Squeeze the spokes together gently with your thumb and fingers to check whether the tension is the same for all spokes.
- If the tension varies or spokes are loose, have a professional check the spokes' tension.
Tires
- Check whether the tire pressure is correct according to the data on the tire side wall.
- Check whether the tires are free of cracks and damage from foreign bodies.
- Check whether you can clearly feel the tire tread.
- If a tire is cracked or damaged, or the tread depth is too low, have the tire replaced by a professional.
Brake
It's important that you learn and remember which brake lever controls which brake (front/rear) in order to ensure your safety. To check which configuration your bike is set up with, squeeze one brake lever and see if the front or rear brake engages. Now do the same with the other brake lever. Remember this configuration.
While you are testing the brake configuration, make sure that your hands can comfortably reach and squeeze the levers with no issues. If you experience any issues or discomfort when operating the brakes, please reach out to us before riding.
Review the brake manufacturer's user manuals and be sure to properly maintain your brakes. It's your responsibility to be able to recognize when your brake pads need to be replaced.
Battery
It's essential to follow these instructions and safety tips in order to preserve the longevity of your battery's life and ensure proper performance.
- Fully charge the battery before each ride to ensure it is ready to go the entire trip. It will help reduce the chance of overdischarging the battery.
- If the battery becomes physically damaged or non-functional, if it has been dropped or involved in a crash, or if you notice that it is performing abnormally, please discontinue use and contact the seller immediately.
- Store the battery in a dry, climate-controlled indoor location at a temperature between 0°C and 40°C.
The voltage drops when the battery is low, which may result in weakened electric power assist. It's recommended that you start charging at 20-40% charge.
| Charge 80-1 | 00% 80% 60 | % 40% 20 | 0% 0-20% | ||
| Battery Voltage/V | 42 38 36 | 34 32 30 |
Charging your battery
- The charger is rated for 100–240V. Be sure to check the charger, the charger cables, and the battery for damage before beginning each charge.
- Charging takes about 3–4 hours. On rare occasions, it may take longer to fully charge the battery, particularly when the bike is new or left unused for a long time.
- Only charge the battery with the supplied charger, as others may cause damage to the battery or increase the possibility of fire or explosion.
- While the charger is designed to automatically stop charging once the battery is full, do not leave it plugged in for more than 12 hours.
- Make sure your charger is isolated from liquids, dirt, and debris.
The range on one charge strongly depends on several circumstances, such as (but not limited to):
- Weather conditions, such as ambient temperature and wind;
- Road conditions, such as elevation and road surface;
- Bike conditions, such as tire pressure and maintenance level;
- Bike usage, such as acceleration and shifting;
- Rider and luggage weight;
- Amount of charge and discharge cycles; • Age and condition of battery.
Charger notes
- The charger should only be used indoors in a cool, dry, well-ventilated area on a flat, stable, hard surface.
- Avoid exposing the charger to liquids, dust, debris, or metallic objects. Do not cover the charger with anything while in use.
- Store and use the charger in a safe area away from children.
- Charging the battery to full before each use helps to prolong its lifespan and reduces the risk of over discharge.
- Do not use any charger other than the original charger you received with your order or a charger designed specifically for the particular bike that you purchased directly from SHARP.
- This charger is designed for standard household AC power sockets with 110-240V 50/60 Hz input voltage, and it automatically detects and calculates the input voltage. Do not attempt to open the charger or modify the voltage input.
- Do not yank or pull on the charging cable. When unplugging, pull on the plastic plug to carefully remove the AC/DC cable.
- It is normal for the charger to become moderately warm during charging. If the charger is too hot to touch, or if you smell an odor or notice any other signs of overheating, stop using the charger and contact the SHARP Service Center.
- Keep the indicator facing up when using the charger. Do not invert the charger, as this can inhibit cooling and shorten its lifespan.
- Only use the original charger provided by SHARP or one designed for your specific bike model that is approved by SHARP. Do not use aftermarket chargers, which may cause damage, serious injury, or death.
- Not following the battery charging information listed here may cause unnecessary damage to the charging components, battery, or charger and may result in poor battery performance or failure to work properly. Battery damage incurred this way is not covered by warranty.
Balancing your battery
When you first receive your bike, it is important to follow these steps to ensure that your battery cells are properly balanced in order to keep them as efficiently as possible.
- For the first initial charge upon receiving your bike (or after prolonged storage time), be sure to charge the battery for at least 4 hours before riding.
NOTE: We recommend letting the battery charge for at least 4 hours for the first three charges to ensure that the cells balance properly.
- After the first three rides, you may begin routine charging procedures.
Checking the electric drive system
- Check all cables to ensure that there is no damage.
- Examine the display for cracks and damage. Check if it is firmly in place.
- Check the control unit for cracks and damage. Check if it is firmly in place.
- Check the rechargeable battery to ensure that there is no damage.
- Check that all plug contacts are correctly in place and reconnect them if necessary.
- Check the cable and the outer casing to confirm that there is no damage.
- Check the motor to ensure that there is no damage.
Cleaning
- Always turn the battery off and remove the charger from the charge port and wall socket before cleaning the battery or bicycle.
- Use a dry or slightly damp cloth for cleaning the battery or bicycle frame. If there is dirt in or around the charge port, try using low air pressure or a soft brush to remove it. For instructions on how to clean drivetrain components, please refer to the drivetrain manufacturer's instructions.
- When cleaning, make sure the charge port on the bicycle is fully closed and no water comes into contact with the electrical components. If wet, leave the charge port open to dry out completely before connecting the charger.
- Be careful not to damage or expose electrical components to water. Do not pressure wash your battery, motor, or any other electrical components. Damaging electrical components or exposing them to water may start a fire which can result in serious injury or even death. Do not use or charge a battery you believe had water seep inside. Likewise, all connectors, including the charge port, must be completely dry and clean before using or charging the bicycle.
- Do not use alcohol, solvents, or abrasive cleaners to clean the charger. Instead, use a dry or slightly damp cloth. Surface cleaning the bike ONLY.

Pumping the bicycle tire
To pump the tires, you will need:
A bicycle pump compatible with Presta valves or
A Presta valve adapter (if your pump does not have a built-in Presta valve head) is not included.
How to pump the tire
a. If your pump has a dual head (fits both Presta and Schrader valves), make sure it is set for Presta valves. If your pump is not Presta-compatible, you will need a Presta valve adapter. Attach the adapter to the pump head. b. On the bike, unscrew the small nut on top of the Presta valve by turning it counterclockwise. This allows the valve to open and air to flow into the tire. c. Press the Presta valve to release a small amount of air. This helps ensure the valve is not stuck and allows the pump to engage properly. d. Press the pump onto the Presta valve as far as possible. e. If your pump has a lever, flip it down to secure the pump head onto the Presta valve. This creates an airtight connection. f. Begin pumping air into the tire. g. When you reach the desired tire pressure, detach the pump head by releasing the lever or unscrewing it. h. Screw the small nut on top of the Presta valve clockwise to close it.
How to use the e-bike
Fully charge the battery before first use.
How to charge
a. Open the rubber cap and connect the charger to the e-bike charging port [Figure 11-1]. Make sure the charger plug is oriented correctly, as shown in [Figure 11-2]. b. Plug the charger into an AC wall outlet. c. When connected to the battery charger, the battery will start charging and the charging indicator on the charger will turn red. d. After charging is complete, the charging indicator will turn green. Remove the battery charger when fully charged. e. Close the rubber cap after charging.
