How to choose a bike?

Exercise and health are an eternal topic. The ways of sports are also becoming more and more diverse. Many people are also pursuing some exercise on weekdays. Cycling is a good choice. For the athletes, outdoor cycling can not only exercise, but more importantly, it can breathe fresh air. It can be said to be a double benefit! So how do you pick a bike?

The first is to see what your purpose for riding a bike is.

1, the general work, go to school, buy things, then you can use the general light car, preferably a relatively large basket, can put a school bag or something. There are also conditions to buy a car with a variable speed or a bike with a variable speed.

2. If you have slopes or bridges on the road and you feel that the uphill and the bridge are too much trouble, you should not choose a bicycle with a transmission; if you are on a road that is not a smooth paved road, you will Should choose wider tires and bicycles with transmissions;

3. If you are riding long distances a day, you should choose a bicycle with a transmission and a narrow tire; if it is a short distance, you should choose a light car;

4. If you are in a place where it often rains, you should choose a bike with fenders;

5. If you have more chances to ride at night, you should choose a bicycle with lights.

Let's take a look at the key points to pay attention to when buying a bicycle.

First, the frame:

The frame is equivalent to the human skeleton, with the frame can be installed on a variety of bicycle parts. The frame consists of iron, aluminum alloy and other materials, and the characteristics of the overall bicycle are affected by the angle formed by the length of the pipe. For example, bicycles that ride well on a straight line, bicycles that are easy to turn, bicycles that ride well, and so on, determine that many of these factors come from the frame.

What can be considered a good frame? Light, strong, and good elasticity are among the goals pursued by the frame. To achieve this goal, we must also look at the techniques of each frame manufacturer. If the design of the frame is based on the strength and characteristics of the material to design, welding process is mature. These have a direct impact on the appearance, strength and flexibility of the frame. There is also a more important spray paint, a good paint spray frame, and spray 3-4 layers of paint. Do not underestimate the spray paint. A good spray paint can make the bike easy to maintain and not rust. If you use a frame that does not meet the above requirements to load your car, you may be able to produce a bicycle that is not straight or difficult to turn, or a bicycle that is quickly retired. Most of the material of the frame is the iron frame, but the iron frame is also divided into chromium molybdenum steel, high-strength steel, ordinary steel, etc. In the iron added to other extremely frame, after adding these other components can be made Thin tubes, for example, make the overall frame lighter. Recently, on the basis of not reducing the strength, there have been frames that use materials other than iron, such as aluminum alloys. In the bicycle race there is a frame made of titanium metal carbon fiber material.

Second, the parts are composed of:

What is a bicycle part? Various parts mounted on the frame have their own functions. For example, the brake is to stop the bike safely; the pedal is to transmit power to the wheels and so on. The specialized factories that manufacture and sell these parts are called bicycle parts manufacturers. Famous parts manufacturers develop new products every year. These products are provided to major bicycle manufacturers and then appear on the market.

What is the best bike part? Simply speaking, it is light and strong, and its performance is better. 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 in the price of bicycles. The best part is to be able to participate in parts of the Olympic cycling competition. The best materials are used in both strength and weight.

III. Assembling a good part If you do not have a good part, it will be like a house that has not been designed by an architect or an experienced craftsman to make you worry about it all the time, for fear that it will collapse. Therefore, if you do not want to buy a later regret, you should understand this knowledge. The most critical one is the transmission and the brakes.

If you buy a bicycle purely for sports, you should pay attention. Sports cars are different from ordinary bicycles, and its outstanding requirements are to be solid. The frame must withstand tremendous pressure, shock and vibration without breaking or deforming. The rim must be double-layered so that the inner tube will not be damaged during exercise. It should be noted that the car belts must be purchased in pairs (the front and rear belts have different patterns. This is the need for different forces before and after exercise). Kit performance is better, as far as possible, the suite should try to choose high-end.
