(2) Forget the cruiser. Go with a mountian bike. The coaster brake is a real nightmare to deal with. The rear hub on a crusier is as big round, and in some cases bigger round than the center hole in the spocket. The rear hub on a mountian bike isn't much bigger than a pencil and the sproket fits nicly on the spokes. Good luck, and have fun old man.
Get a hub-sprocket adapter, It will save a lotta grief and make builds easier and when you decide to change bikes, a lot easier to transfer motor gear to the new one
