Electronic control stepless speed changing bicycle

Abstract

The invention discloses an electronic control stepless speed changing bicycle. The electronic control stepless speed changing bicycle comprises a frame, a saddle, a front wheel, a rear wheel, a framebox body, a handlebar, a battery and a motor, wherein the frame box body is arranged at the middle part of the frame, the saddle is arranged at the top of the frame box body, and the battery is arranged in a cross beam of the frame at the front side of the frame box body; the handlebar is arranged at the upper part of the front end of the frame, the front wheel is arranged at the lower part of thefront end of the frame, the rear wheel is arranged at the lower part of the rear end of the frame, and the motor driving the rear wheel to rotate is arranged on an axle of the rear wheel. The electronic control stepless speed changing bicycle disclosed by the invention can change speed at any time and is not limited by any riding condition; electronic control stepless speed changing is adopted, regulating range is wider, and a speed changing process is smooth; structure is reasonable, reliability is higher, and service life is long; a reciprocating pedaling way is more fit to a physiologicalstructure of a human body, and pedaling efficiency is higher; and a hinge joint of a pedal in the reciprocating pedaling way is arranged at the center of the lower part of the pedal, all the strengthof feet while pedaling can be transmitted to a crank, and loss of force is reduced.

Description

technical field

[0001] The invention relates to the technical field of bicycles, in particular to an electronically controlled continuously variable speed bicycle. Background technique

[0002] With the development of society, the continuous increase of private cars has led to serious road congestion, and the advantages of bicycles are light, flexible, small, and can pass through congested streets and alleys. But there are following problems in traditional variable speed bicycles:

[0003] 1) The traditional chain and gear disc speed change cannot be changed when going uphill or pedaling vigorously, otherwise it will cause impact on the chain and gear disc;

[0004] 2) The traditional chain and gear plate shifting are stepped shifting, there will be a sense of frustration when shifting gears, and the coordination of hands and feet is required. If the skills are not skilled, there will be a strong sense of impact, and even the chain will drop;

[0005] 3) The traditional ch...
