7. Common Fault Checking and Solutions
7.1 Bike Without Motor Assistance
If the display lights up and the motor works when the throttle is pushed or using the walk function, but there is no power assistance when turning the pedals:
o Check whether the pedal sensor is working normally…
Check the space between Magnet disc and sensor is 2-3mm; and,
Check if the sensor indicating light is flashing when you turn the crank in the forward direction.
o Check whether the plug between the controller and the sensor is inserted correctly and that the pins are not bent/broken.
o If no fault is found, take the bike to your dealer to check if the controller is faulty.
If the display lights up, but the motor doesn’t work if you push the throttle or turn the crank or use walk mode:
o Check whether the controller and the connecting cable are loose or damaged, or whether the plug is inserted correctly and that the pins are not bent/broken.
o Check whether the motor connection is loose or damaged, or whether the plug is inserted correctly and that the pins are not bent/broken.
o Check whether the pedal sensor is working normally
Check the space between Magnet disc and sensor is 2-3mm; and,
Check if the sensor indicating light is flashing when you turn the crank in the forward direction.
o If no fault is found, take the bike to your dealer to check if the controller and/or motor are faulty.
7.2 Display Does Not Turn On
Use a Multimeter to check the battery discharge voltage (the battery voltage should generally read more than 31.5 volts – if below this, take to your dealer).
Check whether the battery plug is properly installed, and whether the positive and negative electrodes are installed correctly.
If no fault is found, take the bike to your dealer to check if the display and/or controller and/or harness are faulty.
8. Bicycle Inspection and Care
Regularly clean your bike. Its a good way to notice any problems before they cause damage.
8.1 Regular Cleaning & Storage
Wipe any dirty painted or plastic parts with a soft, damp cloth and a neutral cleaning solution. Carefully dry the parts with a soft, dry cloth to finish.
DO NOT use water to clean the electrical components as this could result in personal injury or malfunction of the bicycle.
DO NOT grease or use a greasy cloth to wipe down the electrical connectors, brake pads, wheels, tyres or plastic parts.
DO NOT use a pressure washer as this can force water into the electrical components.
Always dry the bike with a soft, dry cloth after riding in or exposure to rain.
