    Chapter 4: Riding operation

    1. Pre-use Inspection

    Please note that before use, support the vehicle with center kickstand, and start the following checks:

    • Check the steering column for smooth rotation and any looseness or jamming.
    • Check the battery for sufficient charge to ensure reliable driving.
    • Check the braking system for smooth and reliable operation.
    • Check the surface condition and inflation pressure of the front and rear tires.
    • Check the accelerator for smooth and effective operation and the electric motor for normal functioning.

    2. Start-up

    • Secure the vehicle support, and the driver should sit in the driver's seat with their hand on the throttle and engage the handbrake.
    • Insert the key into the ignition switch and turn it to the "ON" position. Power is on; check the battery level using the power indicator. Release the handbrake only after confirming there are no abnormalities. If any abnormalities are detected, immediately turn the key to turn off the power.

    3. Driving

    • Forward: In the startup state, hold the handlebar with both hands, gently turn the throttle handle, the vehicle starts moving forward, and you can control the vehicle's forward speed with the throttle.
    • Reverse: After braking, put the vehicle in a stopped state, long press the reverse button, then gently turn the throttle handle, the vehicle starts to reverse, release this button to stop reversing. You can control the vehicle's speed with the throttle.
    • When starting uphill, pull the handbrake, shift the gear to "1", slowly turn the throttle handle, and simultaneously slowly release the handbrake. After normal driving, you can shift to 2nd or 3rd gear.

    4. Methods for handling situations during driving

    • When braking is needed, release the accelerator with the right hand, grip the handbrake firmly with both hands until the vehicle stops, press the "P" switch, and the vehicle enters a braking state. In this state, turning the throttle handle will not allow the vehicle to move. If you need to continue driving, press "”.The vehicle returns to standby mode, turn the throttle handle, and the vehicle can continue to drive.
    • When turning, it is necessary to turn on the trun signals, and off the signals after turning.
    • During driving, if the power indicator is in the red area, it indicates that the power is insufficient, and it should be charged in time to extend the battery life.
    • In low visibility conditions, please turn on your headlights promptly and adjust the high/low beam switch as needed.
    • When going downhill with a heavy load or on a steep slope, use a low gear. If the speed is too fast, use the brakes to control the speed, allowing the vehicle to enter the steep slope descent mode to ensure safe driving.

    5. Parking

    If you stop driving, park the vehicle securely, turn the electric lock to the "OFF" position, remove the key, pull down the side stand, and use it to support the vehicle.

    6. Driving in rain or snow weather

    Please drive cautiously in rainy or snowy weather.

    Chapter 5: Charging precautions

    • When charging, turn off the vehicle power switch and remove the key to prevent accidental factors from causing the vehicle to start suddenly.
    • You must use the charger equipped with this vehicle for charging. Pay attention to the battery type and applicable voltage that the charger can charge, and strictly prohibit mixing use.
    • Do not charge in enclosed places or where the temperature is very high or where flammable and explosive items are placed.
    • When charging, first connect the charger's output plug to the battery's charging socket, then connect the charger's input plug to a 110V AC power source. A red light on the charger indicates it is charging; when the indicator light turns green, the battery is fully charged.
    • During the charging process, if the indicator light is abnormal, an odor is detected, or the charger casing becomes excessively hot, stop charging immediately and inspect the charger.
    • After charging is complete, first unplug the power cord, then unplug the connector to the battery. It is strictly forbidden to leave the charger connected to the AC power supply for an extended period of time without charging.
    • When using or storing the charger, avoid water or other liquids entering to prevent internal short circuits of the charger. When it is confirmed that the battery is low and needs charging, ensure that the input power plug makes reliable contact with the AC power socket.

    Chapter 6: Battery maintenance

    • When the new vehicle is used for the first time, the battery should be fully charged.
    • After each use of the bike, check the battery level. If the battery is low, charge it promptly. If the bike is stored unused for a long period, it should also be charged regularly (once a month) to help extend the battery's service life.
    • While riding, if the battery level indicator is in the red area, charge it as soon as possible. Avoid over-discharging. Undercharging, overcharging, and over-discharging can all damage the battery and shorten its service life.
    • Avoid getting wet.
    • Keep the battery surface clean and dry, and avoid proximity to open flames or high-temperature heat sources. During hot seasons, it is strictly prohibited to expose it to direct sunlight.
    • Ensure good ventilation around the battery.
    • Used batteries should not be discarded or disposed of arbitrarily to avoid environmental pollution.

    Chapter 7: Motor usage and maintenance

    • The motor should be used in a dry and well-ventilated environment to facilitate rapid heat dissipation.
    • When starting, do not set the accelerator to the maximum to avoid excessive starting current that could damage the motor; if the vehicle is obstructed and cannot start, do not repeatedly attempt to start it. Wait to troubleshoot and resolve the issue before starting again.
    • The battery voltage should be maintained between 63-78V, otherwise it may affect the normal operation of the motor or prevent it from reaching its rated performance.
    • The motor should be avoided from contact with water, and it is prohibited to ride in relatively high water surfaces.
    • When driving on poor road conditions, the motor should operate at low speed to avoid strong vibrations.
    • When the user checks and maintains the motor, it must be done under power-off conditions, checking the tightness of the bolts, and tightening them in a timely manner if loose.

    Chapter 8: Maintenance and maintenance schedule table

    The vehicle should be maintained and serviced according to regulations, which can ensure your driving safety and also extend the vehicle's service life.
