Got the rear wheel (48vGM) , installed today ,it is totally lock up….?
I’m trying to use a 36v GM controller with a 48 v GM throttle and 48v motor.
Got the horn working “nothing else” Got any ideas?
Scott,
Did the wheel turn OK before you connected any wires? If you're not sure, try disconnecting the three main motor wires and see if it then turns OK by hand.
If it's tight to turn with the motor wires unplugged, make sure it's not touching the frame or binding against the brakes etc.
If you haven't fitted the spacer tube on the freewheel side it could be locked up solid against the freewheel.
GM state that this hubmotor will take up to a six speed freewheel, more than six sprockets may cause a problem.
I would make sure there is clearance between the end of the freewheel and the dropouts.
If you think the freewheel may be the problem, slacken the nut which secures the axle on the freewheel side and see if the wheel turns, just to confirm it.
