Unlike of many other concepts electric bicycle concept HMK 561 from Ralf Kittmann took home an iF Design Award for some seriously forward thinking. Cyclists HMK 561 is made of conductive carbon fiber, which is not only an excellent conductor of electricity, but also acts as a capacitor that can store energy. This energy is obtained by converting the mechanical energy into electrical energy in each mobile connection of mechanism. The resulting energy fed to the engine and lights. And there is already a working prototype!
