You need to measure the outside diameter of your wheel hub to see if the adapter will fit. Some people make adapters for them. Here is a link to my single speed Bruiser. http://motorbicycling.com/showthread.php?p=581475#post581475
 
I have a Micargi 7 speed cruiser with a rear hub that measures .988" on the O.D. & I have yet to find a hub kit to fit anything quite this small. I'll bet if you purchase an engine kit with the 'spoke-sandwich' set-up, you will become dissatisfied and eventually want an adapter for that hub. Your best bet may be to shop for your ride carrying a set of calipers.
 
By golly, for those sort of prices I'll bet if I have to I can fabricate shims that will compensate for a few thousands of an inch. That is an interesting post, although that clunker of mine isn't up to handling a 36 tooth sprocket quite yet.
 
They have different sprockets. Just go to the site and check the sprocket section. This should work fine with no shims. My hub measures .995 and there is still a small gap on the clamp of a several thou. This is a very nice quality product at a good $$.

I've gone ahead & ordered a King's 1" adapter with the 44t sprocket, and since a few more bucks on the order would qualify me for free shipping and I was already looking at other carburetors, I chose a plain NT with a nice jet selection.
Now, I wait for that free shipping - probably arrive along with the Easter bunny. ;)
 
Yeah I did the same with the $60 free shipping. I got a new muffler for only $4 more. You will like the adapter/sprocket it good quality. If you want to move up to a 36t later let me know, I went to a 32t and didn't use the 36. Make you a deal.
 
Pete, you need to measure that rear hub O.D. to be sure, but I have a suspicion many manufacturers have the same sources for certain parts. If you don't have your own calipers, borrow a set, or even a 1-2" micrometer will do the trick if you can wiggle it between those spokes & hold it in position.
Once you're sure of your size you can choose the correct adapter for your hub.
