Magnetic bicycle wheel

If not for road bicycle than for light EV motorcycle such idea could find some reality:

 The bicycle wheel consist of hard rubber ring 1 connected with light carbon flat rim 2  with inserted permanent magnets 3 (they are drilled in, not disturb the carbon structure). The opposite base 4 contain electric magnets 5 which support and rotate the wheel.
So small magnet levitation reduce the friction, suspend the bike, propel and harvest the motion.
