Zero Bike

The Zero Bike was designed in 1988 (!) by Makota Makita and Hiroshi Tsuzaki, then students at Art Center College of Design in Los Angeles.

Rather than spokes around a hub, this concept bicycle has wheel rims cradled by magnets, using the principle of magnetic superconductivity, also used in high-speed trains that are suspended above rails.

Not only does it look mighty interesting, the absence of spokes it is beneficial for the aerodynamics of the bike. Less is more! ;-)
