Sweet ride man! I was reading up on your build a bit, and yours is a true heavy duti, lol. I can't imagine pedaling it around without power from the engine. The mag wheels are no doubt one of the smarter ways to go, just not sure they'd fit the look I'm after. I may re-lace the rear only with 10?ga spokes, like the heavy duti, and just go with caliper brakes like robe suggested. Wally world doesn't sell real bikes imo, just disposable cr@p. I have just one aluminum framed bike, only because it was inherited. The rest are Japanese steel for road bikes, American for cruisers and mtb.
