Re: Lehr Propoane motorized bikes
That doesn't sound bad. Is that the same 4 stroke engine (in the video) that the Staton kit uses? The Staton one is really nice, and has a nice cage for the bottle, where a fuel tank would usually go on a similar motor. You could build a rack on the other side to hold 2 other bottles, to extend your range.
