I have been looking for an upgrade to the stock xb-600 motor. It seems that most of the motors available are for mopeds. The ebike type motors really arent more powerful than the stock motor. Goldenmotor says it has a 1000w motor mounted in a 12in rim so it should fit the back of the xb-600. It is just an ebike hub motor though and I am not sure how you would put the rear brakes on it. Maybe someone knows the answer to this?
I tried to measure the rear fork to see how wide it is but that is difficult with the wheel still attached. I think it's close to 8 inches wide. Does anyone know if the xm-3000 motors or any 3x10 hub motor for a moped will bolt on to the rear of the xb-600? I guess I should be concerned with the front wheel and putting 3x10 on their as well.
