Description

Universal pushing wheel for bicycle Technical Field The utility model relates to the technical field of bicycles, in particular to a universal pushing wheel of a bicycle. Background The bicycle is a two-wheeled traffic tool driven by stepping pedals by manpower, and mainly comprises a frame, wheels, a transmission system (chain, a toothed disc and a flywheel), a braking device (brake), a handlebar, a seat and other parts, wherein the frame is of a triangle structure, the stability during riding is ensured, the wheels are connected with a wheel hub and a wheel rim through spokes, a pneumatic tire provides a damping effect, the transmission system converts pedaling force into driving force to enable the wheels to rotate, and the brake is realized by friction of the wheel rim or the disc. In the daily use process, some existing bicycles are designed to be foldable for carrying conveniently, but after the bicycle is folded, because part of the bicycles are heavy integrally, users are difficult to carry the bicycles to move, and the problem of inconvenience in the whole carrying process is caused. Disclosure of utility model The utility model aims to solve the problem that the bicycle is inconvenient in the whole carrying process because a part of the bicycle is heavy in whole after being folded in the prior art and is difficult to be carried up and moved by a user.
