How about twin engines?

The 'Double whiz' runs, and runs well... She's loud. fast. and kicks ###(backside)!!!

Why not hook one engine for firstgear and the other for second gear with a double sprocket on the rear? one sprocket 44 teeth and the other 22 teeth. then the tricky part is disengaging one and engaging the other. I suspect around 50 MPH.
