This is my first motorbike build. I have a Schwinn Stingray single speed. I got the bike from a yard sale and the axle needed to be replaced. Since I can't find the axle by itself, I was forced to replace the whole hub. This is getting more and more expensive. The hub costs more than the bike did. I got a 50cc kit from Boy Go Fast, and I don't want to buy a mounting kit or exhaust mod or a sprocket adaptor. I know this is not recommended, but is it possible? Is there anybody who has done this?
OCC Stingray first time

sorry, but you need them. I tried to do a stingray, dosent work.
If i were you i would buy the adapters, or sell the stingray
heres a list of good bikes: http://motorbicycling.com/f31/plug-play-bikes-2-stroke-china-9686.html
And i myself have ahd 5 attemts to find a bike for my 48cc, none worked,
I also advise you not to get a bike with a fat frame, or coaster brakes, and if you can before you get a bike take off the back tire and test the sprocket. Also, bring the bracket that come on the motor mount and lay it on the frame to see if it fits.
Good Luck!

this bike is also my first build, i studied alot on doing a bike like this before picking mine up off criagslist, and i was aware it wasn't gonna be just buying then engine kit and slapping it on. i just haven't had the money for all the parts which just to get it up and running at its cheapest with no extras is $125 for the engine kit, $48 for the engine mount and $59 for the sprocket and hub adapter which puts it over $200.but i think its gonna be a much nicer ride when its done than doing a mountain bike.hope you have better luck on this build.

yes,you will need the sprocket adapter cause the one in the engine kit won't work,id recommend taking a look here SPROCKET ADAPTER , just under 60 bucks and you'll get a top quality hub and sprocket.
edit, the purpose of the sprocket adapter is so the gear will line up with the engine sprocket

So I won't have to buy the sprocket adaptor?

i haven't bought my kit yet,im going off what other people have said in other posts here on doing this project,ive been talking and reading off this forum since march or may trying to figgure out what i need to do mine,what people have said is that a coaster brake set up on a motorized bicycle isn't a good idea cause they can lock up and burn out, and the occ schwinn stingray hub because how wide it is needs like a 'top hat adapter' or sprocket adapter like the link i mentioned earlier,however fairracing31 says he didn't need one and ill believe him.

All I did was re-drill new holes in the sprocket and hub and added nuts and bolts with lock washers. Not much space so you have to drill correctly or you are screwed.
I also used some Grade8 M5 bolts and nut's. The center of the sprocket should rest against the lip on the hub, which will keep the sprocket out far enough to clear the tire with the chain and line up the rear sprocket and drive sprocket on the motor. I also used small spacers on each of the bolts that bolt the sprocket to the hub. With the sprocket against the lip of the hub there is a gap between the sprocket and hub.
Although I really doubt a spacer between the hub and sprocket are really needed but this was for a customer so I added a small spacer that fit each bolt so there was no space between the hub and sprocket. This will also help just in case the lip on the hub wears down the sprocket will stay aligned.
I did find two pics before my camera died, sorry no close-up of sprocket. Ignore the exhaust that was before we had one made for it, this was when we were just testing it out. Alex is my Motorized Bicycle builder partner, he is the one test riding the chopper.
