Ralf Kittmann recently won major accolades among the design community for his electric bicycle concept HMK 561. Below is the fully functional prototype made from “conductive carbon fiber, which is not only an excellent conductor of electricity, but also acts as a capacitor that can store energy.”
Traditionally, e-bikes have a battery stored in the bulky frame somewhere, but this new concept allows the carbon fiber frame to create and transmit power to the motor & lights between the rims. With this new idea, you sit essentially on the battery, which is charged through the frame when you’re pedaling! BRILLIANT!
