A: Please consult the instruction manual to understand the fault type corresponding to the error code and follow the instructions. If the problem persists, please provide a picture/video of the error code. Q: Charger not working. A: First, check if the charger indicator light is green or alternating between red and green during charging. If the green light is constantly on, the problem may be with the charger/charging port/battery. If the red and green lights alternate, the charger is working normally, and the problem may be with the dashboard. Q: Dashboard won't turn on. A: Check if the dashboard cable/controller cable is plugged in securely and unplug and replug it. If it still won't turn on, the problem may be with the dashboard/main cable/controller. Q: Assist function not working. A: Check if the dashboard parameters are correct, confirm if the throttle is working, and check if the sensor cable is damaged or loose. If everything is normal, replace the sensor. Q: Rear wheel vibration. A: Check if the spokes are loose and properly installed. You can tighten the spokes and reinstall the rear wheel. Q: Motor not working/Very noisy A: Check if the controller is loose, and reconnect/reconnect the rear wheel motor cable; please provide a video of the noise so that technicians can determine the source of the noise. Q: Battery not working/Insufficient battery life A: Measure the battery voltage after fully charging (please provide a photo). If the voltage is abnormal, there may be a problem with the battery/battery cover/circuit board. For battery life issues, please test the battery life with a full charge and provide the voltage (VOL) when fully charged, the range (ODO) when fully charged, the voltage (VOL) when the battery is depleted, and the range (ODO) when the battery is depleted. Q: Pedals cannot be installed A: Check if the left and right pedals are installed/tightened backwards. If so, check if the crank/pedal threads are slipping. If slipping, the crank and pedals need to be replaced. Q: Brake failure/Insensitive/Leaking brakes A: First, adjust the brakes/check if the brake pads are worn. If there are oil stains on the brake pads or brake discs, insufficient friction/loose brake lines/leaking brakes, the brakes need to be replaced directly. Q: The brakes are making an unusual noise. A: This could be the sound of the brake disc rubbing. Please check if the brake disc is deformed. If it's not deformed, adjusting the brake disc should solve the problem. The brake disc may be stuck in the middle (with a gap), so don't place it too close to the left or right side of the brake disc. Q: The handlebar stem is loose and has a gap. A: Check if the headset is aligned and properly installed, and adjust the headset. If this doesn't work, replace the headset.
