Combining a 50cc 4-stroke engine with an electric motor gives the hybrid Pi X 30bhp and the ability to travel at freeway speeds. The rest of the major components, including the fuel tank, are housed inside the aluminum monocoque frame. If 250mpg plus a 30-mile electric range aren’t green enough for you, there’s a pedals-only version too.
