Bicycle

Abstract

The invention provides a bicycle to solve the problem of an up-down reciprocating pedaling type bicycle with the application number being 2017100141840. A left pedal and a right pedal are alternatively pedaled in a reciprocating manner, continuous pedaling force output can be generated, the pedaling force utilization rate is high, the physical consumption can be greatly reduced, no dead angle exists in pedaling, the larger pedaling force output can be easily acquired by adjusting the pedaling angle and controlling the reciprocating and alternative swing angles of pedal arms, backward pushing can also be convenient, the wheel locking phenomenon cannot occur, and the bicycle has the beneficial effects that riding is convenient, the structure is simple, the appearance is changed slightly, and the bicycle can be easily accepted by a rider.

Description

technical field [0001] The invention belongs to the technical field of bicycles and relates to a bicycle. Background technique [0002] The basic structure of the existing bicycle is that pedal arms and pedals are fixedly installed at the two ends of the central shaft at the lower part of the bicycle frame, and the sprocket wheel on the central shaft is driven to rotate by the circular circulation of the rider's both feet, and through The chain drives the sprocket wheel on the rear wheel to rotate to push the bicycle forward, which has the advantages of simple structure and the like, and brings great convenience to people's travel. [0003] But there are also major disadvantages. Since the two pedal arms need to be set at 180°, when riding, the bicycle needs to have a certain speed before the two pedals can cross the top dead center and bottom dead center to form a circular motion. , to complete a relatively stable pedaling force output, and only when the pedal is stepped f...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned shortcomings of the published up and down reciprocating pedaling bicycle, the application number is 2017100141840, the present invention provides a bicycle, which can generate continuous pedaling force output by alternately pedaling the left and right pedals, and has pedaling force The utilization rate is high, which can greatly reduce physical energy consumption, and there is no dead angle when pedaling. It is easy to adjust the pedaling angle and control the reciprocating and alternating swinging angle of the pedal arm to obtain greater pedaling force output, and it is also convenient to push backwards. The phenomenon of wheel locking occurs, which has the advantages of convenient riding, simple structure, minor changes in appearance, and easy acceptance by riders.
