Hand-foot compound bicycle with double ratchets

By designing a double ratchet power transmission system in the bicycle, the problem of limited driving speed and unnatural arm movement caused by the arms and legs pressing the pedals separately is solved, achieving natural movement and efficient power transmission driven by the coordinated use of hands and feet.

Description

technical field

[0001] The present invention relates to a compound bicycle, and more particularly, to a compound bicycle having a double ratchet in which handle power and pedal power are stably and efficiently transmitted to wheels. Background technique

[0002] Typically, bicycles allow the rider to pedal with their feet and control posture and direction with their hands.

[0003] So, in terms of exercise, the legs are doing a lot and the arms are doing a little bit. Moreover, the speed at which the bicycle can travel is limited.

[0004] Meanwhile, in order to solve the above-mentioned problems, attempts have been made to improve the structure of the bicycle so that the rider can ride the bicycle while using his / her hands and feet complexly.

[0005] However, the conventionally proposed bicycle has problems in that its structure is complicated, the speed difference between the front wheel and the rear wheel is inconvenient, and the arm moves unnaturally.

[0006] In add...
