I own a 34cc Two-Stroke chainsaw engine that i am not currently using, and figured I might as well put it on a bike. My first question - is 34cc's enough to get the bike up to a good speed? I'm 6-foot and around 160 pounds, if that helps. I also want to mount the engine in a way that, if I run out of gas or if the engine fails, I can still be able to pedal. Any help with these questions is greatly appreciated.
