For my first build I thought I would start cheap so I Bought a Huffy Santa Fe from K-Mart for $130 and the 66cc engine kit off ebay for about the same price. Only other purchases so far are replacement (higher quality) tubes and a front caliper brake (The Tektro one off Amazon) that was just delivered. Everything went together pretty easily but there is a little play in the rear wheel bearings I will have to try and correct. I Plan on doing that and firing it up for the first time tonight.
