Jim Wilson at Pedalchopper.com also has a very slick setup using a three speed hub with billet cnc mounts and shifter. Retains original bicycle drive chain with motor jackshafted and freewheeled.I must not have explained myself very well. I need the bicycle peddle crank system with sprockets/jackshaft so pedaling system is directly tied to engine. Motoped, Sportsman Flyer, etc., all use a peddle/jackshaft system. I need this drive type system, the motor and all other parts are easy for me.
