Deacon, I know you don't like the speed that you get with a larger wheel, but instead of changeing the wheel, change the rear sprocket to a larger one. I don't know what size your running now but I've seen up to 52t for sale from venders. A more economical solution for you is to find an old Schwinn exercycle, they have a 60t and have been told some have a 64t solid sprocker that could easily be drilled to make a moto drive sprocket. Just a thought...Kelly
