HMK 561 Bike
Posted on July 21, 2010 in Transport design

The HMK 561 designed by Ralf Kittmann is a carbon fiber bike that uses a special carbon filament to conduct and monitor electrical properties that hold power right inside the frame. Carbon fiber is highly conductive so the designer uses it as a power distribution network instead of wires. Power is delivered via two electric motors which are housed in the opposite direction to the force applied to the wheels which allows for regenerative braking as well. Use of counter-turning axle in lieu of gears and chains reduces part count and production costs.source
