Problems solved by technology

[0003] In order to solve the above-mentioned shortcomings, the present invention provides a freewheel body with automatic unlocking when reversing. The body and the wheels are in a locked state when the pedals are stepped on, and the body and wheels are in an unlocked state when the pedals are not stepped on. The rear wheels can be Reverse free rotation, the pedals do not rotate when reversing, and when applied to a folding bicycle, the wheels will not be unable to rotate due to the obstruction of the pedals by other parts on the bicycle, and the phenomenon of wheel locking will not occur. Convenient, simple structure, no riding noise, long service life, easy to accept by riders, etc.

Abstract

In order to overcome disadvantages, the invention provides a tower base for automatic unlocking for bicycle backing. When paddles are stepped on for riding, the tower base and a wheel are in a lockedstate; when the paddles are not stepped on, the tower base and the wheel are in an unlocked state, and the rear wheel can freely rotate forwardly and reversely; the paddles do not rotate during bicycle backing. When the tower base is applied on a folding bicycle, it cannot occur that the wheels cannot rotate due to the impediment of other parts on the bicycle subjected by the paddles, and a locking phenomenon of the wheels cannot occur. The tower base for automatic unlocking for bicycle backing has the advantages that riding is convenient, the structure is simple, no riding noise is generated,the service life is long, and a cyclist accepts the tower base easily.

Description

technical field [0001] The invention belongs to the technical field of bicycles and relates to a tower base with automatic unlocking when reversing. Background technique [0002] When the current bicycle is reversing, because the ratchet ratchet on the rear wheel is always in a locked state, it will drive the chainring to rotate synchronously through the chain, and the pedals fixedly connected to the chainring will also rotate synchronously. Towing will drive the pedals to rotate, because the pedals of the folded bicycle are hindered by other parts on the bicycle and cannot rotate, so that the bicycle can only be towed in one direction after folding, which brings inconvenience to the use of the bicycle At the same time, the ratchet ratchet on the rear wheel will make noise and long-term use will cause wear and tear, which will affect the daily use of the bicycle. Contents of the invention [0003] In order to solve the above-mentioned shortcomings, the present invention p...
