I just purchased a Motobecane E-mulekick electric bike. With a Bafang M800 electric mid drive. Rode it for 12 miles everything worked great. Now The only thing that works is the display. I can't change the pedal assist modes from 1-5 and the pedal assist does not work. I was able to get into the codes and it does have an error code of 25 which shows to be a torque sensor. Bikes Direct and Bafang have not been real supportive other then e-mailing a manual although the manual does not tell me here the torque sensor is located. Does anyone have any ideas?
