First thing to do will be to check if the cable is properly plugged in
If it is not:
1. Check the arrow direction on the cable coming from the front wheel.
2. Check the arrow direction on the connection port on the fork.
3. Align both arrows and firmly insert the cable.
If that’s not the case, try to see if the wheel has resistance when turning by hand. Then unplug the motor and see if the resistance goes away. If that is the case, there’s an issue with the controller and not with the wheel.
Please send us a video describing the issue.
