I cannot get to the controller yet, the owner has locked the battery to the frame. This is a manufactured bike, not a conversion. It was brought to me to have some spokes replaced. when refitting the wheel there seemed to be little or no power to drive the hub. I have stripped the motor down and...

I am working on an Effbike where it is having drive problems. Lack of power to the hub motor. I have stripped the hub, replaced the clutch, and when testing with the cover off the drive seems to want to go into reverse. I am suspecting a short somewhere or a controller (build in) failure...
