Device of automatic speed change bicycle

Abstract

The invention provides a device of an automatic speed change bicycle. The device mainly comprises a bicycle body, a rotating body arranged on the bicycle body as well as a speed change system, wherein the speed change system is used for adjusting a chain group arranged on the bicycle body according to a rotation rate of the rotating body so as to perform relative speed change operation; when the speed of the bicycle body is gets higher during driving, relatively, the rotating body is impacted by more wind relatively, so thatand rotation at a relative speed is caused changing of the relative speed is caused; and the rotating speed of the rotating body is calculated by the speed change system to simulate a current driving speed of the bicycle body and a corresponding speed change is performed, a user can enjoy convenience and pleasure of automatic speed change during riding, and the trouble of manual speed change is not causedavoided.

Description

technical field [0001] The invention relates to a bicycle, in particular to a device for an automatic speed-shifting bicycle that does not require manual shifting by a user. Background technique [0002] In recent years, the usefulness of bicycles has been gradually recognized by people. The popularization of bicycles as sports has further promoted the development of bicycle speed change operating devices. In the early days, bicycles did not have so-called speed change functions. Therefore, when the road surface was steep, it became very difficult to ride. Therefore, in order to solve the problem of riding on steep slopes, The phenomenon of difficulty, some manufacturers have developed a variable speed bicycle. This kind of bicycle with variable speed is widely loved by the public. The rider's riding environment is used to change the shifting position to achieve riding optimization. [0003] However, the general speed change system manually toggles the speed change lever a...
