I bought a small frame boy's mountain bike for my mom.

And the frame can't take engine so I was thinking about rear mounted 4 stroke.

This is a pretty nice bike for its price, very well built too since dick's sporting goods have a bike technician that properly assembles bikes and tunes it up for you, and the derailuer shifts gears so smoothly, seemed like such a waste not to jackshaft it.

Anyone try using Sick Bike Parts jack shaft kit for four stroke engines on a post mounted engines?
