This is what I have been doing this winter.I built myself a pretty nice strech.It has a 50cc Morini Franco Engine.The back wheel was built by the Wheel Master it has 8 gauge spokes it is pretty tough.The frame I got from materlowrider.com it is cool.The gas tank is a round one gallon tank that I got off E-BAY.The exhust I got from Pipelyne.I have a 44 tooth sproket on it and I cad cruise at 40mph with ease.It is a little loud but I love it.
