So bin working on a Flip-Flop wheel with a Fixey sprocket on the right side and a 54 tooth sprocket on the right side of the hub. The sprocket has a tooth pitch of 5/8 inch and is ready to accept the 8 mm T8F chain from the pocket bike engine or a small 4 stroke.
At the moment I am leaning towards the 4 stroke after my experience with the Lifan 152f I am blown away by the quietness and low end torque of 4 strokes.
Looking for input from anyone with experience in this type of set-up in a bike.
The engine that I have in mind for the Flip-Flop wheel is the Lifan 139f 2.
