Re: Alternatives to Jim's Sprocket Adapter
You could try livefastmotors, but not sure. Isn't that hub a large O.D., like 3-4"? I know livefast sells sprocket adapters for either coaster brakes or multi-speed bikes and also can be ground a bit if they need to be resized. But if it's one of those larger hubs, you may have to try and bribe someone to make one.
Don't feed the bears....
