Hello, I guess..
Well, first off, i'm Connor, call my FriSk. Anyhow, I built a motorized bike for my buddie awhile back and i'm thinking about doing one for me. Since last year or so, i've been riding my mountain bike for distance, and now i'm going to attempt to put a motor just for coasting, and going up hills.
When I did his bike, I had a electric start, 3HP ( or 3.5HP ) Bridge and Straton motor on it, with a simple throttle control on it. Only problem was that it would flip if he didn't put all his body weight into the front. Anyhow, ya..
