wanna sell it? me and my uncle were gonna build one but my buddies dad gave his bike away. use a golf cart rear axle and streering box. the axles are super strong ans you'll have both wheels spinning.also they use a steering box that is very small and works really well.the frame is probably best to fabricate youreslf because it will have to be pretty long. if this is for the street you wont really need any suspension. let me know how it works out for you.also all you have to do for the axle is weld in a sprocket and turn the engine so the chain goes right around and make a lever for the shirter.you may have to put a handle on the steering wheel for a clutch though. good luck on the brakes.
