Problems solved by technology

Because people's feet have to make a circular motion accordingly, due to the limitation of the structure of the car body, the design of the pedal rod of the traditional bicycle pedal is generally shorter.
If you ride for a long time, your lower limbs will feel sore, causing physical fatigue and affecting the quality of travel

Abstract

The invention belongs to the technical field of walking-replacing tools, in particular to a pedal-type bicycle. In the bicycle, a front wheel and a rear wheel are connected into a whole by a bicycle body and consists of a bicycle frame and a vertical pipe, the bicycle body is provided with a bicycle saddle, a bicycle handle and a pedal-driven transmission mechanism, and the transmission mechanism consists of a pedal, a flipper, a speed changer and a chain wheel device. The flipper consists of a compressed spring, a sleeve pipe and a parallelogram hinged expansion rod which are sleeved on the vertical pipe, and a rack for driving the speed changer to transmit is arranged at the back side of the sleeve; the speed changer is arranged on a support frame, a gear of the speed changer is engaged with the rack of the flipper, and a ratchet is coaxially connected with a drive chain wheel of a chain wheel device; and a driven chain wheel of the chain wheel device is connected with a wheel shaft of the rear wheel of the bicycle body. The invention satisfies the normal walking habits of the human body, thereby lightening the pain sense of the legs caused by riding for a long time so as to enable the riding process to be more comfortable and labor-saving. The speed change function of the speed changer enables the velocity of the bicycle to obviously quicken so as to improve the outgoing quality.

Description

1. Technical field [0001] The invention belongs to the technical field of walking tools, and in particular relates to a pedal bicycle. 2. Background technology [0002] Bicycles have become an important means of transportation for people today. The traditional bicycles that people use need to pedal with both feet to make a circular motion, and the power is transmitted to the rear wheel through the sprocket device to make the car move forward. Because people's both feet also will make circular motion thereupon, because of the restriction of vehicle body self structure, the pedal bar design of traditional bicycle pedal is generally shorter. If you ride for a long time, your lower limbs will feel sore, which will cause physical fatigue and affect the quality of travel. 3. Contents of the invention [0003] The object of the present invention is to provide a bicycle that drives the vehicle body forward by stepping repeatedly, which can reduce the fatigue of long-time riding....
