just a thought....but what about a compressed air bike?
should be extremely simple, just wouldn't have much of a range. might be nice as a little hill-assist feature on a regular bike though
just mount one small tank that could help you up one or two steep hills. or just give you a crazy blast of speed, kinda like a BOOST button
