Re: Help with a cool project please.
I agree with CabinFever, DO NOT drill holes in your frame! You can buy exhaust clamps at your local auto parts store. Vice, hammer, and drill are the only tools you will need to shape a piece of steel to adapt your motor to your bike. Cool bike, I would do a Sick Bike parts shift kit and take advantage of the multi-speed hub. Never used one with internal geared hub but there is nothing like taking off from a stop light without pedal assist and shifting gears!
