"It's one of the first bikes in the world to have no rear hub. The rear wheel has a special magnetically polarized rim that is suspended inside the frame, where it floats inside a magnetic suspension field. You've already figured out what that means. Fewer moving parts, less friction, more speed! As an added plus, the magnetic suspension field cushions your ride. The drive train is also based on a magnetic principle, so powering the pedals creates incredible speed in no time."
