Abstract

The invention relates to a bicycle which comprises a front wheel and a frame assembly, and the front wheel and the frame assembly are in rotating connection; the bicycle also comprises a rear wheel driving mechanism mounted on the frame assembly; the rear wheel driving mechanism comprises a rear wheel, a power lever assembly, a resetting assembly, a pedal and a rotating wheel; the resetting assembly is connected with the power lever assembly so as to be used for enabling the power lever assembly to reset; one end of the power lever assembly is connected with the pedal, and the other end of the power lever assembly is connected with the rotating wheel so as to be used for driving the rotating wheel to rotate; the rotating wheel is connected with the rear wheel so as to be used for driving the rear wheel to rotate in one direction; and the rear wheel driving mechanism is also connected with a seat mechanism. The bicycle provided by the invention can solve the problems that the bicycle is laborious and a chain is damageable.

Description

technical field [0001] The invention relates to a bicycle, in particular to a chainless bicycle driven by a lever. Background technique [0002] Bicycles have always been a means of transportation for the people of our country to go out, but with the development of my country's economy and the effort of bicycles, people are using more and more vehicles such as motorcycles, electric vehicles and automobiles. The increase of bicycles has led to many problems such as environmental pollution, traffic jams, and insecurity. The country also advocates green travel, but traditional bicycles are laborious. The root cause of the labor is: its power arm (the radius of the pedal rotation) L1 is always smaller than the radius L2 of the rear wheel , according to the principle of leverage F1×L1=F2×L2 (where F1 is the force of people stepping on the pedal, and F2 is the force on the rear wheel), it can be known that F1 is greater than F2, that is, the force of people stepping on the pedal mak...
