Okay I need a friction drive for the china engine. I am getting so sick of the chain drive I don't know what to do. So here is what I need.

Take an alum or steel channel.
Use brass busings to run a shaft through with a sprocket on the motor side to drive a shaft with a friction drive roller on it. You might half to do a gear thing to make it change directions but it shouldn't be all that hard to do. I can rig the tie downs no problem. It would be just a bolt down on the wishbone behind the seat, then a couple of down rods to the rear axle. Nothing to it for someone with a good shop.

That kind of rig would eliminate broken spokes, chains jumping off in he middle of traffic, and give another option for the china bike kit. I know I'm the only one with a desire to run friction drive these days, but I swear I think it is more dependable.

The reason I like the china girl engine for the power source is the the clutch. A motors that sit on the tire running continually will wear spots in the tire for sure, but the clutch would make it like my electric where I just shut it down before it spins.

So build it and they will come, at least I will if the price is right.

Come on Norman you and a lot of other guys can do this no sweat
