Oh wow. That sounds delux. So it takes a BMX style freewheel then?
Yeah the sprocket on the spokes is a last ditch, cheap *** way to do it. The kit makers tell you set up is easy, but I bet its a real bear to get that sucker lined up. Its probably easier to lace and tighten a wheel. I've built wheels for several years. Its not hard, but set up is critical, and its time consuming.
