What three materials are bicycles made of?

Bicycle consists of frame, transmission, wheel set, handlebar set, brake and other parts. The frame is made of aluminum alloy, steel, carbon fiber and other materials. Carbon fiber frames are expensive and lightest, and most of them are 606 1 aluminum alloy frames on the market. The composition is as follows:

1. Body parts: including

Frame, front fork, handlebar, seat and front fork are the main parts of a bicycle. The transmission part includes pedal, crank, sprocket, chain, central shaft and flywheel. The pedal is stepped by manpower, and the wheel is driven to rotate and drive forward through the transmission parts.

2. Action part: front wheel and rear wheel, including front wheel and rear wheel axle, spokes, rims (rims), tires, etc.

3. Safety devices: including brakes (brakes), lights, bells, mirrors, etc.

shopping tips

Lightweight, firmness and good elasticity are one of the goals pursued by the frame. In order to achieve this goal, it depends on the technology of various frame manufacturers. For example, whether the designed frame is designed according to the strength and characteristics of materials and whether the welding process is mature. These directly affect the appearance, strength and elasticity of the frame.

More importantly, painting. A good picture frame, painted evenly, sprayed with 3-4 layers of paint. Don't underestimate spray painting. Good painting can make bicycles easy to maintain and not easy to rust. If a car is loaded with a frame that does not meet the above requirements, it is possible to produce a bicycle that cannot ride in a straight line or turn easily, or a bicycle that will soon break down.
