Schwinn Stingray O.C. chopper motorized bicycle


   It is a Schwinn Stingray bike designed by Orange County Choppers for Schwinn.  Only made for a couple of years around 2005.  The basic bicycle is in very good condition aside from for the seat, which has some minor splitting in the vinyl covering.  Has a standard bicycle 24 inch front wheel, and an extra wide 4.25×20 inch rear wheel and tire.  Despite the fact that it has smaller wheels, the wheelbase is  much longer than a standard 26 inch bicycle and is an adult size bike, but in case you are over 6 feet tall, the bike may be a bit small for you.  I am 5ft 4in. and the bike is a very comfortable size for me, and I only have the seat adjusted about half way toward the maximum height.

   I have added an  80cc/66cc gas 2-stroke motor kit to this bike.  I bought a kit specifically put together for this particular Schwinn bike,  with all the extra parts needed for a proper installation.  The extras include a special offset motor mount for this frame,  extra chain length, and modified muffler( standard muffler will not clear the pedals).  Also included were a better balanced one piece crankshaft for smoother running, especially at high RPM,  a speed carburetor for higher fuel/air mixture( more power). 

  I added some modifications of my own, most important,  a smaller 38 tooth sprocket gear to compensate for the much smaller 20 inch rear wheel and tire.   This produces about the same final drive ratio as the standard 44 tooth gear does on a 26 inch wheel.  Also,  I modified the chain idler to bolt through the frame instead of the standard clamp on. Needs much less adjusting and futzing with.  I put this bike together properly and took extra time where needed to insure things worked properly.  This is my third bicycle motor install project, so I have some experience with it.

    I have just completed the required break-in period, running the first gallon of fuel with a 16:1 fuel/ oil mix ratio, the second gallon with a 20:1 mix ratio.  All through the first gallon, the engine was never run at more than half throttle.  All through the second gallon, was only run at full throttle for short periods.  I am now into my third gallon of fuel and the engine just keeps running smoother and better and is in a position to run at higher RPM’s.  Also, All through the first week of running,  the head bolts were checked and re-torqued on a daily basis before running.

   It is a fun bike to ride and will cruise around at 20-25 mph easily and tops out at about 30 mph.

  You must make arrangements to pick this bike up personally.  I will be able to not ship this.  You’ll pay with Paypal or cash when the bike is picked up.

   You are welcome to come and inspect the bike in person before you make a decision to buy.

           Thanks for looking.
