Problems solved by technology

However, there are the following problems: 1. The pedals cannot rotate in a circle, and need to relearn or adapt to the new riding mode; 2. The length of the crank is set to be short, although it can make the crank move away from the parts of the rear wheel to avoid conflicts , but due to the limited torque, the effect of labor saving and speed increase is average

Abstract

The invention discloses a crow bar bending bicycle. A first crow bar and a second crow bar are arranged to be not in the same straight line, the first crow bar and the second crow bar are staggered in the vertical direction, the first crow bar and a pedal assembly are movably arranged in a matched mode, and the second crow bar avoids a hub shaft of a rear wheel and is rotationally hinged to the rear portion of a bicycle frame; the connecting piece movably arranged on the first crow bar rotates by 360 degrees along with the rotating rod to drive the crow bars to swing back and forth along the hinge shafts of the crow bars, the curved bar on the second crow bar drives the rear wheels to walk through the flywheel curved motion mechanism, re-learning is not needed, the riding mode is adapted, and fastest and most labor-saving purposes can be achieved; on the other hand, the diameter of a front wheel is reduced, a proper length extension space is provided for the crow bar, and the size of the bicycle is not increased additionally.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a crowbar cranking bicycle. Background technique [0002] Traditional bicycle is to connect pedal lever by pedal, and pedal lever connects big sprocket, and big sprocket is connected with the little flywheel on the rear wheel by chain, and little flywheel drives rear wheel to rotate, and bicycle can be walked. Since the bicycle is powered by the crank pedal, and is limited by the height of the bicycle frame and the range of motion of the human leg, the crank length of the bicycle is limited, and it is not labor-saving when riding. The only way to increase the pedaling frequency is to reduce The weight of the body is used to increase the speed, and it is easy to get tired during long-distance riding. [0003] In order to solve the above problems, some improvements to bicycles have been made on the market, making it more labor-saving when riding. For example, the patent No. "202...
