• Check plug connections.  
  • Disconnect the E-brake lever and retest. 
  • Carefully turn the bike upside down and turn the pedals. A red light should flash regularly on the pedal sensor. If the sensor does not flash, it is most likely defective.  
  • Check the cable routing of the cables leaving the controller. These must neither be bent nor damaged. (Example: NCM Moscow 48V - controller cable may have been damaged by kickstand or gear). 
  • Testing the walk-mode: Lift the wheel with the motor and activate walk mode via the display according to the operating instructions. If the walk mode works properly, a defect of the pedal sensor/controller is possible.
