It will be the bike of the future: without chains, faster and lighter

Determined to put an end to these problems, the Danish firm CeramicSpeed ​​developed, in collaboration with the Department of Mechanical Engineering of the University of Colorado, a bicycle qualified as "the most efficient in the world".

Prototype "Driven" works from a power transmission system that does not require strings. With this proposal, he won one of the awards awarded as part of this year's Eurobike Award with Driven, a concept of energy transmission that he developed in collaboration with the engineering department. Mechanics of the University of Colorado.

CeramicSpeed ​​is connected by a carbon fiber shaft that rotates 90 degrees to the rear wheel and pedals. At each end of the shaft are 21 small, low-friction ceramic pieces that transfer the energy generated by pedaling the driver across an axis and toward the rear sprocket

As explained by his creators, "CeramicSpeed ​​has achieved a powertrain It achieves a 99% efficiency at the same time, and at the same time we manage to eliminate an object as obsolete as the chain, which tends to stretch and s & # 39; 39, especially when the cyclist is constantly changing speed. This means that almost nothing of the power generated by the legs of a cyclist is lost.

The company believes that this new technology could be applied to tracks, triathlon and electric bicycles.

The prototype contains 13 gears, but its creators badure that more gears could be added easily. CeramicSpeed ​​exhibited the invention at the Eurobike fair in Germany, between 8 and 10 July, while its inventors process the patent and carry out new tests.
