Re: what did you do to your motorized bicycle today?
Yep the best setup would be the differential,you can get them from Northerntool.com or any one of the go kart suppliers. With them both wheels pull and ratchet's around corners.I had some out of lawn tractors but the are offset and have a short axle on one side. You almost need 2 get the long axle out the second one. But that depends on the tractor some are wide enough. Sad is they are hard to find now as they were mostly on older tractors.
