I bought a coaster break hub off of e-bay about a year ago for about $20 because it was really heavy duty looking made in Germony and has a oiler hole and weighs about 2 lbs, and was going to make a wheel for my motorized bike with it. I took it apart cleaned it up and then greesed it up and put it back together. When I went to build my wheel I realized that the hub was about a fraction of an inch larger than a regular hub, so the spokes would be smaller in length,so I put off making the wheel. I found a old mountain bike that someone was throwing away, and it had these really big old school mountain bike wheels on it Araya, I am now thinking about just taking these mountain bike wheels apart and taking the wheel and hub to the shop and making a heavy duty wheel, any ideas on what kind of spokes to use and how much I will end up paying and that sort of thing? Any advice is helpfull. I will post pictures if anyone is interested. The hub and wheels are pretty cool the rim is straight. Am I just wasteing my time?
