Well, it actually has a serious problem in reverse. A couple of days ago, when you hit reverse, it took a while to get going, but it would go in reverseon flat ground or down hill. Now it wont even get the wheels turning in reverse, but will almost pop a wheelie in forward. Yesterday, we hit the pedal in reverse and after a few seconds saw smoke from the motor....Not good, huh? The cables to the motor all seem good, so I'm thinking maybe one of the studs on the motor may not be making good contact internally on the motor, and the amperage can't get through in reverse....what do you think? Obviously the windings, brushes, bearings, etc are ok, cuz the motor works great in forward....
