6. E-bike Troubleshooting
– Dealer use only
Problem: Motor assistance does not work at all, display works fine
The display lights up but the motor
doesn’t work – even if the throttle is used, the bike is pedalled or if the 6km/h walk mode is
selected.
Solutions
：
A). Check if the controller and the connecting line are loose or damaged, or if the contact pin is inserted crookedly;
B). Check if the motor connector is loose or damaged, or if the contact pin is inserted crookedly;
C). Check whether the sensor works normally or abnormally;
Please check the space between Magnets disc and sensor (2-3mm is normal);
Please check if the sensor light is flashing or not when pedaling;
D). Change to a new motor to check if the problem persists;
E). Change to a new controller to check if the problem persists;
F). If there is a motor patch cord, please check if the patch cord works normally or not;
Problem: Front or rear light does not work
Firstly, check if the batteries of the front or rear light are flat
– if so, replace with new ones;
Check if the batteries are inserted correctly (positive to negative) and that they are seated correctly. Try testing with a new light to
see if the issue is with the light itself rather than the battery. If there is a light module, please check if the wiring sequence is correct.
If there is a head light patch cord, check if the wiring connection sequence is correct.
If the above methods are unsuccessful, please change the controller.
