Default Re: Would you like to help a bunch of teenagers go fast?

I seem to recall a forum member installing this vertical engine on his DIY rear friction drive. He mounted it vertically and used a Craftsman-type long socket to rub against the rear tire's sidewall. The bike got up to 30-something mph speed. However, I'm unsure if it ate rear tires quickly.
