Zhejiang Hangyi Bicycle Manufacturing Company begins from Hangzhou Yuanshi Industrial Co.,Ltd,
Classic city bicycle was the most important means of transportation in the last century. Today, more and more people choose cars or public transportation as their first choice to go outside. Bicycles usually refer to small two-wheeled land vehicles. After a person rides on the car, he uses his foot on the pedal as the driving force, which is a green and environmentally friendly transportation tool.
Many simple mechanical principles are used in bicycles. The lever principle is applied to both the handle and the brake grip. Between the pedal, crank and the large sprocket, and between the small sprocket and the rear wheel, the wheel axle principle is applied. The large sprocket drives the small sprocket via the chain, using the principle of gears. The screw refers to the principle of the inclined plane. The application of these principles makes bicycles more time-saving and convenient.
Among the 25 components of the bicycle frame, tires, pedals, brakes, and chains, none of the basic components are indispensable. Among them, the frame is the skeleton of the bicycle, and it bears the heaviest weight of people and goods.
According to the working characteristics of each component, it can be roughly divided into the guiding system, driving system, and braking system. The guiding system consists of handlebars, front forks, front axles, front wheels and other components. Riders can change the direction of travel and maintain body balance by manipulating the handlebars.
The drive system is composed of pedals, bottom axle, chainring, crank, chain, flywheel, rear axle, rear-wheel and other components. The pedaling force of a person's foot is transmitted by the crank, sprocket, chain, flywheel, rear axle and other components by pedaling so that the bicycle can continue to move forward.
The brake system is composed of brake components, and the rider can manipulate the brake at any time to slow down and stop the driving bicycle and ensure driving safety. In addition, for safety and aesthetics, as well as for practicality, car lights, brackets and other components are also assembled.
