Chainless bicycles ride with pedals, which is more labor-saving than traditional bicycles?

Bicycles are no stranger to everyone. Since its invention, this environmentally friendly and healthy way of traveling has been deeply loved by many consumers. Once upon a time, bicycles were one of the main means of transportation in China. However, with the passage of time and the development of technology, more and more modes of travel have replaced the position of bicycles in people's lives, so many people have begun to have various ideas about the renewal and change of bicycles.

No, an engineer from Germany joined hands with a university to develop a pinion shaft drive system, which changed the principle of traditional bicycles. We all know that the traditional bicycle, also called chain bicycle, connects the pedal with the rear wheel with a chain, so that people can get enough kinetic energy when stepping on the pedal, and then transfer this kinetic energy to the rear wheel, so that the bicycle can keep moving forward.

But in this way, in fact, there is a lot of friction in many positions of the chain and bearing, and when these friction forces are added together, people have to use more force, which wastes a lot of kinetic energy invisibly and makes the rider very tired.

The pinion shaft drive system DrivEn, which is composed of a single chain, a carbon fiber shaft with a speed of 13 and a set of 2 1 ceramic bearings, can effectively reduce all kinds of friction consumed by bicycles. In the actual test, the bicycle driven by the pinion shaft drive system reduces the friction by 49% compared with the traditional chain bicycle, and the power conversion rate reaches 99%, which means that it saves half.
