The invention relates to an electronic transmission and a bicycle. The electronic transmission comprises a gearbox component, a guide wheel component, a tensioning component, a connecting rod component and a power source component. The speed change device has the advantages that the gear box component drives the guide wheel component through the connecting rod component and the tensioning component to guide the chain into the fluted disc of the corresponding gear, compared with the prior art, no steel cable or hose or other structures exist, and the situation that the speed change device fails due to stretching, aging, breakage and other factors can be avoided; and through the parallelogram structure of the connecting rod component, the gearbox component can drive the tensioning component to drive the guide wheel component to move in parallel, and rapid and accurate speed change is achieved.

    本发明涉及一种电子变速器及自行车,电子变速器包括齿轮箱部件、导轮部件、张紧部件、连杆部件和电源部件。其优点在于,齿轮箱部件通过连杆部件、张紧部件驱动导轮部件将链条导入对应档位的齿盘上,相比现有技术,无钢索、软管等结构,可避免由于拉伸、老化、断裂等因素造成变速装置失效;还通过连杆部件的平行四边形结构,使得齿轮箱部件可驱动张紧部件带动导轮部件平行移动,实现变速的快捷、精准。
