Thinking caps on because this takes some imagination to digest. The HMK 561 is a carbon fiber bike with special 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. The power drives the lights and the motors in between the rims but get this… there’s regenerative braking. All that energy drives a system that turns the wheels using a counter-turning axel in lieu of gears and chains. Far fetched? No, because there’s already a prototype.
