Problems solved by technology

The patent No. CN94222761.1 is the technical scheme of the bicycle adjustable variable speed crank. Subjectively, it shortens the crank to a certain length and at the same time must keep a certain crank length to ensure the pedal to adjust the riding speed. The distance is close, but this closeness is only caused by the pedal driving state and is limited. It cannot make the two sides of the stirrups symmetrical and meet the comfort requirements of the motor vehicle pedals.

Description

technical field [0001] The invention relates to the technical field of bicycle pedals, in particular to a pedal of a moped. The moped is a multifunctional power-assisted bicycle with human drive, power drive or both human drive and power drive. Background technique [0002] Power-assisted bicycles are easy to use and have become an important means of transportation that is becoming increasingly popular. When manual drive or manual drive and power drive are used together, the feet move up and down around the central axis on both sides of the car body in a circular motion; but when the power drive is used, the feet are in a rest state, and the feet should be placed symmetrically on the car body. The position of the central axis on both sides is in line with the principles of human mechanics engineering; in summary, when the car body is driven by human power, the stirrups on both sides of the car body are staggered up and down, left and right, and when the power is driven, the...
