[BikerModder]

Oh I see I know all that srry. Did not get that at first. I think the friction or fan clutch is what the other thread forum member wanted a way to add a derailleur to a motor driven pedal car. The Ranger I had was a bit advanced older car with the 8 plugs and 4 cylinders. But it was years into advancement and the development cost was in the millions of dollars and 4 or 5 years to get into produce. It is a great ride and I think the mod might benefit with velcro like the other modders have been added.
