Choose a bike, see what time, urgent urgent!
Choose a bike is mainly a good look at the frame, two to see whether it is a good part of the composition, and three to see whether the assembly technology is good or not. By combining these three factors scientifically, they can be regarded as a good bicycle.I. frame:What's the 1. frame?Frame equivalent to the human skeleton, with a frame to install a variety of bicycle parts. The frame is composed of iron, aluminum alloy and other materials, and the overall characteristics of the bicycle are influenced by the angle of the length of the pipe and so on. For example, straight riding, better cycling, easy to turn bicycles, riding a comfortable bike, etc., decided that many of these factors come from the frame.
1. what is a bicycle part?Mounted on the frame of various parts have their respective roles, for example, is to make the bicycle safety brake pedal to stop; specialized factories to power the wheels and so on, the production and sale of these parts is called bicycle parts manufacturers, parts manufacturers famous every year to develop new products, these products also provide for the bicycle manufacturer, then appear on the market.2. what is the best part of a bicycle?To put it simply, it's light and strong, and better performance. Because of these conditions, it is easy, safe and convenient for a bicycle to ride. But to achieve all of the above conditions, good materials are needed. Therefore, bicycle parts are often a factor in the price of bicycles. The best thing is to be able to take part in the Olympic cycling events. The best materials are the strength, the performance, and the weight.
3. what are the materials in the frame?Most of the iron frame, but also iron frame into chrome molybdenum steel, high strength steel, ordinary steel and adding other extremely in iron frame, add to these other components, such as can be made thinner pipes, making the whole frame lighter. Recently, on the basis of not reducing the strength, there has been the use of materials other than iron, such as aluminum alloy materials. A frame with titanium carbon fiber material used in a bicycle race.
2. how to be a good frame?Light, rigid, flexible and so on, is one of the goals pursued by the frame. In order to achieve this goal, we also need to look at the technology of each frame manufacturer. If the designed frame is designed according to the strength and characteristics of the material, is the welding process mature?. These have a direct bearing on the appearance, strength and elasticity of the frame. What's more important is spray paint. The good frame is painted evenly and sprayed with 3-4 layers of paint. Do not despise the spray paint, good spray can make the bicycle easy maintenance, not easy to rust. If you use a frame that does not meet the requirements above, it is possible to produce a bicycle that cannot be ridden straight or not easily turned, or a bicycle that will soon be returned.
