HMK 561 | Electric Bike
Ralf Kittmann took home an iF Design Award for his electric bicycle concept HMK 561. This ultralight zero-emission bike concept and design is clearly novel. Unlike most concept designs we see, Kittmann created a working prototype constructed from conductive carbon fiber, which is not only an excellent conductor of electricity, but also acts as a capacitor that can store energy. Energy from the carbon fiber frame is capable of transmitting power to drive the lights and the motors in between the rims of the HMK 561. Moreover, the bike also feature a regenerative braking mechanism that turns the wheels using a counter-turning axle without any gears or chains. This energy is obtained by converting the mechanical energy into electrical energy in each mobile connection of mechanism and the resulting energy is then fed to the engine and lights.

wow!This is super cool !
I’m not very good at understanding mechanisms, but does one have to pedal this things? or does is work with the switch of a button??

See the spoke that connects to the wheels? It is almost touching the inner rims. That is a source of friction. No metal can be sturdy at that mm distance tolerance. They are going to bang against each other.
And yes, where are the pedals?
what a load of shit. I would like to see this tested forst before making such claims.
twist the handle to move and stop?

Looks like a 1:1 model. A working prototype implies that the various electro-mechanical aspects are all present in some form, and that doesn’t seem likely at this stage of the design (no pedals, no energy storage, no motors described – unless they were just able to demonstrate regenerative braking?)
This is terrible – so many flaws to the design…
Firstly – why does it need two sets of wheels, for people toe fat to pedal, secondly…. ZZZzzzzzz
[...] Electric Bike By abrentisart Sent from Treezoy, this thing is crazy. Eco-friendly, zero emission, carbon fiber, with a counter-turning axle, and the double wheels are pretty ingenius. See more here. [...]
[...] A energia do quadro de fibra de carbono é capaz de transmitir força para dirigir as luzes e os motores entre as margens da HMK 561. Além disso, a bicicleta também possui um mecanismo de freio regenerativo que vira as rodas usando um contra-eixo girando sem marchas ou correntes. Esta energia é obtida através da conversão de energia mecânica em energia elétrica em cada conexão móvel do mecanismo e a energia resultante serve de alimento para o motor e as luzes….. Mais [...]
