I was going to try a friction drive but decided to just get a kit. I see many on ebay and just don't know which to buy. My main use if it works is to ride into town and back on a regular basis. Tow is a 15 mile ride, 30 mile round trip. Oh yea....I'm on a small budget. Can yall help me out here to make the right choice for a first timer. Thanks a bunch.
