Last week we featured a Belgian chap who claimed to have reinvented the wheel, but now some German engineers are claiming to be reinventing the whole bike.
Möve Bikes say their innovative CyFly drive system will improve pedalling efficiency by 50%, claiming only one third of the energy expended in the pedalling motion is transformed into movement.

While the designers have given away very little about how their idea will actually work so far, they have provided this handy picture on their website, for any budding engineers out there to decipher.
“Most of the force [when pedalling] puts pressure on the bottom bracket, where it is wasted. We use this otherwise unutilized energy and transform it into locomotion as well,” Möve say on their website.
“CyFly as an individually adapted component can make any conventional bicycle, racing bike, downhill bike, cargo bike or e-bike significantly more efficient. Depending on the gear ratio, the extra torque can make pedaling easier or be transformed into a higher speed.
“Exactly how all this works will remain our secret for now.”
