I have a 66cc Flying Horse Engine kit from Bikeberry and plan on mounting it on a Skyhawk Gt2 frame. Is this possible? I've seen pictures of builds where the sprocket is mounted near the crank yet on my diamondback outlook the sprocket needed to be mounted on the rear wheel. How should I go about mounting the engine? Do I need a special system to mount the 36 tooth sprocket where the crank is or simply use the rear wheel hub mount?
