Abstract

The invention discloses a bicycle, and particularly relates to the field of bicycles. The bicycle includes a main rod, wherein a seat cushion is installed at the top of the main rod, a driving shaft is fixedly installed at the bottom of the main rod, a large sprocket movably sleeves the outside of the driving shaft, a pedal is fixedly installed in the front of the large sprocket, and the outer part of the large sprocket is connected with a small sprocket through a chain in a transmission mode, and the small sprocket is internally and movably connected with a linkage rod in a sleeving mode. A baffles and cross bars are fixedly installed on the left side and the right side of the main rod correspondingly, auxiliary rods are fixedly installed at the other ends of the cross bars, and handles are fixedly installed at the tops of the auxiliary rods. According to the bicycle, by arranging two rear wheels and front wheels, the bicycle forms a state of four-point supporting, and the stability of the bicycle in use is greatly ensured; and by arranging bearings on the top of a second sleeve plate, the front wheels are like a universal wheel structure, freely adjusting the direction of riding is convenient, and flexibility is high.

Description

technical field [0001] The invention relates to the technical field of bicycles, and more specifically, the invention relates to a bicycle. Background technique [0002] A bicycle is a small land vehicle with two wheels. After a person rides on the bicycle, it is powered by pedals. It is a green and environmentally friendly means of transportation.
