Among the 25 components of a mountain bike 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 greatest weight of people and goods. According to the working characteristics of each component, it can be roughly divided into guiding system, driving system and braking system:
1. Guiding system: It 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.
2. Drive (transmission or walking) system: It is composed of pedals, bottom bracket, chainring, crank, chain, flywheel, rear axle, rear wheel and other components. The pedaling force of a person's foot is transmitted through cranks, sprockets, chains, flywheels, rear axles and other components by pedals, so that the bicycle can move forward continuously.
3. Braking system: It is composed of brake parts, and the rider can manipulate the brake at any time to slow down and stop the driving bicycle to ensure driving safety.
In addition, for safety and beauty, as well as for practicality, car lights, brackets, car bells and other components are also assembled.Customized Mountain Bike
