I've been thinking about this grand invention for quite a while. Imagine it: a man-powered vehicle like the unicycle, but with two wheels. I think I'll call it a double-unicycle, but it's not quite as catchy as I want it to be. I'm still stuck on how to transport the kinetic energy of the pedals to both wheels, though - I'm thinking some sort of double chain system, where the pedals drive both unicycles. Seat placement could, perhaps, be problematic as well...
