Yeah, except it can also use a sprocket and chain. Same mounting position as a friction drive. Thatsdax.com has both a chain and friction drive rack mount kit. Just put a quality motor on and its bullet proof. The rack mount is a buy once thing, then it will take any motor with that clutch/mounting pattern. For example the titan 50cc 4 stroke, suzuki 4 strokes, pocket bike engines, scooter engines, honda 50, huasheng 50, you name it.
And the whole thing looks much more like a motorized bicycle than a motorcycle (a plus for you right?)
