Operating, Charging, and Using the Battery
Your bike is powered by a lithium-ion (Li-Ion) battery. Always follow the instructions below when operating, charging, and using:
- Vehicle batteries are for use in this vehicle only. It is strictly prohibited to connect the battery to other electronic devices, which may cause a risk of battery damage.
- Be sure to turn off the battery lock before installing and removing the battery.
- Do not modify, open, or disassemble the battery pack. Modifying or disassembling the battery may cause a short circuit, fire, or malfunction.
- Batteries are heavy; please hold them carefully to avoid dropping them.
- Do not allow any sharp or metal objects to touch the battery electrodes and charging jack, as there is a risk of short-circuiting the battery and fire.
- Do not overheat the battery and avoid overexposure to the sun.
- Do not expose the battery to heat from an open flame or radiator.
- Do not immerse the battery in water.
- Turn off the power and unplug the charger or battery before carrying out installation, maintenance, cleaning, or repair. Touching the contacts while the bike is on may cause electric shock or injury.
- If the bike is not used for a long time, please remove the battery and put it in a dry, well-ventilated place. Ensure the storage environment temperature is 25-35°C (Celsius/Fahrenheit). Also, make sure to charge the battery at least once every three months so that the bike battery shows at least 3 cells (40-50%), which will effectively prolong the life of the battery.
- Used batteries must not be disposed of in your household waste when they are unusable! All batteries and chargers must be disposed of in an environmentally friendly manner in accordance with the battery disposal regulations of your country or region.
Battery Charging:
First, connect the DC end of the charger to the battery charging port, then plug the AC end of the charger into the AC wall outlet. At this point, the charger indicator light will be red, indicating that the charging has started. Wait until the charger indicator light turns green, signaling that the battery charging is complete. First, unplug the AC end and then the DC end of the charger in order.
Remove the Battery:
While the bike is folded, rotate the key clockwise fully to disengage the lock core from its position. Now, slide the battery out to remove it.
Install the Battery:
While the bike is folded, insert the battery into the frame. Ensure correct orientation. Turn the key clockwise to the right; the first turn locks the battery box, and the second turn powers on the E-bike.
Vehicle Cleaning and Maintenance
Cleaning:
Before cleaning the vehicle, please turn off and remove the key. Use clean water and neutral detergent for washing, and do not use high-pressure water jets. After cleaning, use a soft cloth or sponge; strictly avoid using metal brushes, sandpaper, etc., to prevent scratching the surface of components. After cleaning, wipe the vehicle dry with a soft cloth.
Storage:
Park the vehicle in a dry and cool indoor environment, avoiding direct sunlight and rain to prevent rusting of components and shorten the lifespan. When storing for an extended period, please turn off the Key (disconnect the lithium battery) to prevent over-discharge.
Note: If you encounter any abnormalities during maintenance, please contact after-sales support or designated authorized service centers.
Component Maintenance
Motor:
- When driving through water, ensure the water level does not exceed the rear wheel's midpoint.
- Regularly check the fastening status around the motor. If nuts are loose, tighten them promptly.
- After the vehicle stops running, perform simple cleaning and protection to prevent debris from entering the motor and affecting normal use. Avoid directly spraying water during cleaning.
- Check whether the motor leads are scratched, and if there are unusual noises during motor operation, contact after-sales support or designated authorized service centers in case of abnormalities.
Controller:
Regularly check the connected components to ensure they are securely fastened.
Battery:
- In case of abnormal battery behavior, please contact after-sales support or designated authorized service centers.
- Avoid using the battery until completely depleted. Aim to maintain it above 20%. Charge promptly after use to extend battery life.
- Never dismantle the battery privately, as it may lead to safety incidents such as electric shock, short-circuit, ignition, or explosion.
- The battery level indicator fully lit or the charger turning green indicates a fully charged battery.
- The suitable storage temperature for the battery is between 0°C and 35°C.
- If the vehicle is not used for an extended period, after fully charging the battery, remove it and place it in a dry and ventilated area. Recharge the battery once every two months using the charger.
- Do not store the battery in a place with a risk of falling. Falling may damage the battery and cause a short circuit, ignition, or explosion.
Charger
Before Charging:
- The charger should be dedicated to the specific vehicle, strictly forbidden for charging non-rechargeable batteries.
- Do not carry the charger with the vehicle to prevent vibration from loosening internal electronic components.
- Confirm that the power source is a 220V AC power supply.
- If damaged wires or loose connections are found, do not use it. Please contact after-sales support or designated authorized service centers.
During Charging:
- When charging, the vehicle should be parked in a safe place, avoiding rain and direct sunlight.
- When charging, insert the charger plug into the vehicle's charging port first, and then plug in the charger's power plug.
- During the charging process, if the indicator lights are abnormal, there is an unusual smell, or the charger's casing becomes too hot, immediately disconnect the charging. Please contact after-sales support or designated authorized service centers.
After Charging:
- After the battery is fully charged, unplug the charger's power plug first, and then unplug the charger's charging plug.
- Once the charger has cooled down, tidy up the power and charging cables and place them in a safe location.
Warning:
- Sufficient ventilation is required during the charging process; keep away from explosive gases and guard against the risk of fire.
- The charger contains high voltage; do not disassemble or replace internal components. In case of any malfunctions, contact after-sales support or designated authorized service centers.
- Avoid keeping the charger connected to the power source for an extended period, operating without a load, or charging multiple vehicles.
- Handle the charger with care, avoiding rough handling.
