How To Choose A Good Bike

How to choose a good bike, first, the frame quality is good, the second, is composed of good bicycle parts, third, assembly technique is good.After these three factors to combine scientifically, can be regarded as a good bike.

1, the frame

1). What is frame?

Frame is equivalent to the skeleton, the frame can be fitted with a variety of bicycle parts.Frame from iron, aluminum, carbon fiber, and so on material, according to the length of the angles of form influence the overall characteristics of the bike. How to create a bike, ride on straight performance outstanding, curve cycling more smoothly, and more comfortable，decided to many of these factors from the frame.

2). How can a good frame?
Light, strong, good elasticity, is important for bicycle frame, in addition to this, and frame production process.Such as whether the design of frame according to the strength of the materials and to design, welding technology is mature.These are directly affect the appearance of the frame, strength and elasticity.There is more important is spray paint, good frame uniform spray paint, spray and 3-4 layers of paint.Don't look down on spray paint, spray paint of good can make the bike is easy to maintain, not easy to rust.If you are using do not conform to the requirements of the above frame to assemble, it is possible to produce cannot ride straight or not easy to turn the bicycle, or discarded bicycle soon.

3）The frame is made up of what materials?
The most is iron frame, but the iron frame is divided into high strength steel, chrome molybdenum steel, ordinary steel, etc., to join other components in the iron frame, after joining the other components, such as thinner pipe can make it, the overall frame lighter.In recent years, on the basis of not reducing strength, use iron frame material, such as aluminum alloy material.To bicycle match with the use of titanium metal carbon fiber frame.

2.parts

1）. What is the bicycle parts

All kinds of parts are installed on the frame has its own role, for example, the brake is to stop the bicycle safety;Pedal is for the power to the wheels, and so on specialized factory, the production of these parts is called a bicycle parts manufacturers, famous parts makers to develop new products every year, these products and provide bicycle manufacturers, and then appear on the market.

2）. What is the best bicycle parts?
Light and strong, and better performance.Because have these conditions the bike ride up easy, safe and convenient.But to achieve all of the above conditions, it need good material.So, bicycle parts is often about bicycle price is one of the most important factor.The best is to be able to attend the Olympic bicycle parts of the game.Both strength and weight of the best materials has been adopted.

3.The assembly technology

1). The assembly technology
If good finishing is not good, would like neither after building stylist elaborate, also does not have experienced craftsmen to build a house, make you on tenterhooks all day long, for fear that it will collapse.So, if you don't want to regret after bought, should understand the knowledge.

2). Bicycle comfortable function

A. derailleur
Many people mistakenly think that the bicycle is equipped with derailleur is to speed up the cycling, one can actually force from the biggest only 0.4 horsepower.Derailleur is to help people to the maximum horsepower easily play tool.

B.What are the advantages of derailleur?
Bicycles are commonly used within the city, within the city there are a lot of slope.Sometimes you ride a bike when they feel their feet suddenly became heavy, with his eyes could not judge the slope is more often.At this time, the role of the derailleur can be fully reflected, if there is one derailleur, at this time as long as you can with a lighter cycling gear can be at ease.Of course, also can be used in the wind.
Derailleur advantages is that it can help you in the case of poor physical strength, reduce your energy consumption effectively.Such as colds, energy consumption cannot too big, so if you ride when selecting the number of teeth on the lighter than ride will be easy.And when the poor woman's body, with strong student takes an exam the tired, age can be flexible use of variable speed bicycle.So the advantage of the variable speed bicycle is really too much.

C. Of variable speed system needs adjustment before (now have part of variable speed bicycle need to fine tune), however, as the successful development of the function of the SIS, made a lot of bicycle assembly the SIS system, with speed as long as the press of a variable speed can be as "kaka" sound and complete the variable speed, so has been don't have to worry about how to operate.

D. when riding don't know where is the variable section for now?
Now in variable speed on the digital display, as long as have a look at the digital display, the latest product of computer liquid crystal display is also used in the FLIGHT DECK electronic display system.The display system can display time, average speed, ride the 17 kinds of function such as total distance.

E. transmission within and outside the transmission
Before know them, it is necessary to know the difference between the transmission within and outside the transmission.Simple speak transmission refers to the transmission is installed on the outside of the bike as a separate parts to use, and the transmission is hidden in the flower drum after working parts.
Outside the transmission directly on the outside, direct contact with the outer space.Transmission is hidden in the interior, not direct contact with the outer space.So, outside the transmission due to the design space is larger, the scope of the variable speed ratio is bigger also, used for mountain bike.But as a result of contact with the outside world rain, dirt, grease, etc., so you must periodically cleaning and maintenance, and the transmission need not regular maintenance, but within the transmission because of the design space is limited, so, the scope of the variable speed ratio is small, usually used for more lightweight bicycle ride in the city.

F. why within variable speed bicycle now has not yet universal?
Within the domestic market, as consumers have not yet realized the charm of variable speed, so the present stage is not common, but in Japan and Western Europe developed countries in speed is very common in Japan (50% of the bicycle is the internal variable speed bicycle).The reason is, of course, no maintenance.Recent new product and automatically by computer induction and miniature motor speed automatic speed changing system.

G. brake is important bicycle parts
Brake is good or bad relationship to your safety and the safety of others, the braking force and braking time is the main factor that determines the brakes, so good braking performance, operating force light is very important.In the Japanese market has a relatively common roller type brake, except on rainy days also can get satisfactory effect as usual, there will be no noise when braking, without maintenance.

4, what kind of bicycle is most suitable for yourself?

What is the purpose of the first is to see you ride a bike, usually go to work, school, buy something to use portable car, it is best to larger basket, can put a bag, etc.And if there is any condition can buy of variable speed bicycle inside or outside of variable speed bicycle.
If you ride the slopes or on the way to the bridge, and you think up hill, on the bridge is very tired very troublesome, you should choose to have the transmission of the bicycle.If you ride on the road is not flat road pavement, you should choose wide tires and have transmission cycle.
If you one day riding distance is very long, you should choose belt transmission and tire narrower bike.If it is short distance should choose light car.
It often rain if you are in place, you should choose the bike with fender, if night ride more, should choose to take light bike and so on.
The bike shops often have a lot of kinds of appearance, color of the bicycle, so, before you go to bike shops, best according to their own actual situation, first will need to determine what kind of bicycle, and then to the bike shop to buy.
