Yes, Great idea.
Ive got a 2o", 21 speed, mono shock, aluminum mountain bike.
I've just purchased a STIHL MS 290 Farm Boss 3.75hp and should recieve it on monday 3/14/04.
I'm leaning as I go.
I plan on running another sprocket on the other side romoving the arms & pedals. Welding a sprocket on clutch.
I'm not sure yet till I get into it. Peace
