1. Frame
The frame is equivalent to the skeleton of a person. Only with a frame can various bicycle parts be mounted. The frame is made of iron, aluminum alloy and other materials. The angle formed according to the length of the pipe affects the characteristics of the overall bike. For example, many of these factors are determined by the frame, such as good straight riding bicycles, easy spinning bicycles, and comfortable riding bicycles.
2. Components
Various parts mounted on the frame have their own functions. For example, braking is to stop the bike safely; Foot pedal is used to transmit power to wheels and so on. It is light and firm, and has good performance. Because of these conditions, it is easy, safe and convenient to ride a bicycle. But to achieve all the above conditions, good materials are needed. Therefore, bicycle parts are often a specific factor affecting the price of bicycles. The best part is to be able to participate in the Olympic cycling competition. The best materials are used for both strength and weight.
3. Assembly technology
1) Transmission
Many people mistakenly believe that the bicycle is equipped with a gearbox to speed up the ride. In fact, the maximum force that people can send out is only 0.4 horsepower. The transmission is just a tool to help people use the maximum horsepower easily.
2) What are the benefits of the transmission?
Generally, bicycles are used in cities. In fact, there are many slopes in cities. For example, sometimes when you ride a bike, your foot suddenly becomes heavy, and there are often many slopes that cannot be judged by your eyes.
The advantage of the transmission is that it can help you effectively reduce your physical consumption in the case of poor physical strength. For example, when you have a cold, you can't consume too much physical strength, so it will be easier if you choose a lighter number of teeth than when you ride. In addition, women who are in poor health, students who are tired of taking exams, and older people can flexibly use variable speed bicycles. So the benefits of variable speed cars are really too many.
3) Brake
The quality of the brake is related to your safety and the safety of others. The braking force and braking time are the main factors that determine the quality of the brake. Therefore, it is important to have good braking performance and light operating force. There is a common roller brake in the Japanese market. Except that it can get satisfactory results in rainy days as usual, the brake will not make noise and will not be repaired.
4. Purpose of cycling
First of all, it depends on your purpose of riding a bike. Generally speaking, you can use a light car to go to work, go to school and buy things. It is better to use a large basket to put schoolbags. If possible, you can buy a car with internal speed change or a bicycle with external speed change.
If you ride on a slope or bridge, and you feel tired when going uphill or on the bridge, you should choose a bike with a transmission.
If it rains frequently in your place, you should choose a bike with mud flaps. If there are more opportunities to ride at night, you should choose a bike with lights, etc
