Abstract

Provided is a bicycle. A rear wheel is connected with a right gear 1, a right gear 2 is connected to a bicycle body support and connected with a right operating crank, the right operating crank is connected with a right pull rod, the right pull rod is connected to a right stepping crank, and the right stepping crank is connected with a right pedal; a user downward steps on the right pedal to drivethe right gear 2 to rotate through the right stepping crank, the right pull rod and the right operating crank, and the right gear 2 drives the right gear 1 to make the rear wheel rotate; the right wheel is connected with a left gear 1, a left gear 2 is connected to the bicycle body support and connected with a left operating crank, the left operating crank is connected with a left pull rod, the left pull rod is connected to a left stepping crank, and the left stepping crank is connected with a left pedal; the user downward steps on the left pedal to make the left gear 2 rotate through the left stepping crank, the left pull rod and the left operating crank, and the left gear 2 drives the left gear 1 to make the rear wheel rotate. Through the transmission, speed change and direction changeof the left gears and the right gears, by means of the cranks and the pull rods, by downward stepping the pedals, the rear wheel has a running function; by means of a lever force-saving principle, labor saving and rapid riding are realized.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a bicycle. Background technique [0002] With the increasingly higher requirements for environmental protection, people love the improvement of physical exercise, and the convenience of travel, more and more people choose bicycles as a means of transportation, especially now the vigorous development of shared bicycles that are popular all over the world, the demand for bicycles is increasing It is getting bigger and bigger; the requirements for the reliability and service life of bicycles are getting higher and higher, and the requirements for riding speed and labor saving are getting higher and higher. But the chain transmission structure that most traditional bicycles adopt at present has short service life, maintenance, and repair cost is high, and riding is unpleasant and strenuous. Contents of the invention [0003] In order to fundamentally overcome the defects of traditional cha...
