Step 1 Select vehicle type

The first problem that new cyclists often encounter is to walk into a car shop or club and find: Why are there so many kinds of cars? In fact, the development of bicycles in the past 20 years has developed in the direction of specialization, so vehicles suitable for various purposes have emerged. Coupled with the bicycle with people as the main body, under the simple premise, a car can only meet the needs of one ethnic group, and it will be classified as a variety of changes like biological evolution. We can divide the common types of cars into three categories: mountain bikes, road bikes and recreational cars. Consumers can decide the appropriate model according to their own usage positioning.

mountain bike

Mountain bike is abbreviated as MTB, which is called mountain bike, mountain bike and mountain bike in Chinese. It has different names according to different regions. Mountain bike is a popular car in recent ten years. Comfortable shock absorption, easy handling, acceptable transmission ratio are the biggest reasons, and rough appearance equals cool, so it has become the mainstream car at present. However, the difference between mountaineering vehicles from entry to summit is very big, and special vehicles are developed according to different terrain and needs. In addition to the most common off-road (XC) or full suspension (FS), there is also a downhill special vehicle (DH) with enhanced shock absorption effect. The choice of novices is mostly between XC with single shock absorber and FS with full shock absorber. The comfort of full shock absorber is better than that of single shock absorber, but the single shock absorber has high pedaling efficiency and light weight, and the price factor also makes the XC and FS models overlap, so consumers must reconsider the demand and price.

Advantages: comfortable, labor-saving, easy to control, cool in appearance, easy to maintain, suitable for all kinds of roads.

Disadvantages: fast riding speed, short riding distance, heavy weight and high complexity.

B bus

Road cars (road cars, sports cars) should be a kind of racing cars, but road cars account for more than 80% of the sales of racing cars, so they are mainly introduced. Road cars have a long history, and the curved handlebars and thin tires are specially designed for racing and chasing riders. For beginners, it is not so easy to control. Competition vehicles are developed according to the needs of competition events, rather than being derived from terrain changes like mountaineering vehicles. The biggest feature of racing car is its light weight and simplicity, which can meet the knight's requirements for speed and distance. The cars derived from the competition also include time racing cars and venue cars. Time trial vehicles are used for road time trial and triathlon vehicles. The rail car has no speed change and brakes, and is specially developed for athletes to compete in special venues.

Advantages: fast riding, long riding, light weight and simplicity.

Disadvantages: low comfort, skilled control, great wear and tear, careful protection.

Recreational vehicle

Leisure vehicles are relatively new models at present, which can be roughly divided into folding bicycles, ATVs, station wagons, electric cars and city cars that emphasize comfort. The most popular models are comfort bicycles and folding bicycles. This paper will introduce these two models. Bicycles were originally used for leisure, but the comfortable bicycles in recreational vehicles give consumers a very relaxed feeling as soon as they get on the bus, and they also pay attention to the improvement of comfort. The appearance also emphasizes modernity with an integrated spindle, allowing users to enjoy the leisure of riding bicycles anytime and anywhere without changing clothes, releasing the pressure of urban life. Folding bicycle is the spirit of bicycle species. Although it is mainly suitable for light riding, it has become the trend of transportation and leisure tourism combined with mass transportation system after functional and lightweight improvement.

Advantages: high comfort, convenient control, convenient combination of four wheels (folding car) and post-modern modeling.

Disadvantages: fast riding, short riding distance, heavy weight, standardization of parts is developing.

Understand specifications

When you have a good idea about the car you like, how do you evaluate the quality of a car and whether its value is in line with its price? There are many details to pay attention to. Traditionally, bicycle selection was divided into two parts, such as: (Japanese is better than Taiwan Province), (front and rear shock absorbers are better than those with only front shock absorbers), and (the more gears, the better). Theoretically, this method seems to give consideration to quality, effect and function, but times are really different! The composition of bicycles is almost as standardized as that of computers. When you choose to buy a computer, you will compare CPU, RAM, hard disk, graphics card and sound card ... When you choose a bicycle, you will also carefully study the basic skills you must learn when choosing a good car. We will sort out the common parts groups of mountain bikes and sports cars, as well as the models and grades of common shock absorbers.

SHIMANO

Japanese bicycle parts manufacturer, producing mountain bikes, road bikes and ordinary recreational vehicles. Road vehicles have high configuration integrity. In mountain bikes and recreational vehicles, parts are sometimes mixed, and most of them will upgrade the rear transmission to improve the use effect.

Ranked as:

Mountain bikes: XTR, Delaur XT, Delaur LX, Delaur, livio, acera, altus, Tournie (TY).

Roads: Durais, Ulte Guerra, 105, Tiagra, Sola.

Comfort: C900, T400, T300, C20 1, C 10 1, C050.

Static Random-Access Memory

The rising star of the spare parts group mainly produces the whole set of spare parts for mountain bikes. X.0 is the highest level for mountain bikes, and the grades are: X.0, 9.0, 7.0, 5.0, 4.0 and 3.0.

Campagnolo

Italy's old factory specializing in road cars and racing cars, transmission and quick release were invented by the first generation CAMPAGNOLO. CAMPAGNOLO, which focuses on aluminum alloy forging technology, has its high-end products collected by fans like works of art, but rarely matched with finished cars. Ranked as: record, choir, centaur, VELOCE, Phantom, Xenon.

D ROCK SHOX

From entry-level cross-country to downhill race, ROCK SHOX has a wide range of product lines, and the lightweight ROCK SHOX is also a professional company that mass-produces the first shock absorber.

Select size

Choosing the size is related to whether you can adapt to your car for a long time. Just like when we buy shoes, we will give priority to choosing the right size. Few people will choose the right size because of the shape of shoes. I suggest you buy a bike with the same spirit as buying shoes. Don't get carried away by the cool appearance of the car, convince yourself to accept it reluctantly, which risks wasting a lot of money. Generally speaking, the size of a single earthquake-proof mountaineering vehicle is between 14 inch and 19 inch. Calculated by the length of the vertical tube of the frame (the distance from the center of the tooth plate to the lock seat tube of the frame), people with the height between 160cm and 185cm are all in the range. It is difficult to find a car if it is very tall or short. However, due to the large adjustment space, fully suspended vehicles are mostly divided into three levels: S, M and L. However, it should be noted that the exposed part of the seat tube bottom of some models will affect the rear suspension actuation. The traditional road vehicles are divided into centimeters, which can be accurate to every centimeter or even half a centimeter, and can be regarded as a tailor-made size. The trendy road cars, especially those with inclined upper and lower pipes, are also distinguished by S, M and L, and then matched with the sizes of seat pipes, faucets and other parts to suit the individual's figure.

The fourth step is price classification

The price of bicycles varies greatly, ranging from several thousand yuan in cycling classes to tens of thousands in competition classes. Although the price difference is great, it is still called (bicycle). In the previous steps, the classification and price difference of bicycles have been roughly analyzed. We put aside the extremes of too low and too high, and regard the price difference as several levels for consumers to choose cars.

First-class three products 1700~3800 yuan

The leisure and entertainment that modern people can be attracted to consume is too diversified. Spend some money to catch up with the riding trend. Cars of this class can also travel with you, but you need to be able to distinguish clearly. What do you want in your heart is a visually dazzling full shock absorber or a hard-working single shock absorber? No matter which one you want to assemble, you must go to a big car shop or club to assemble it. Their word-of-mouth and after-sales service can free you from worries.

B middle class 3800~7500 yuan

This section of the car has entered the stage of grade standardization, and the fully shock-absorbing car has begun to play its due anti-off-road function, and the single shock-absorbing car has entered the entry-level level level of the competition. As long as you have enough physical strength, your car can not only provide you with the ability to travel, but also the quality of its parts and vehicles has reached the rigorous test that can accept the competition. Your bike also looks full of posture because of the improvement of the texture of each part.

C senior consumption is 7500~ 12000 yuan.

If your first car is at this price, you will get two things. First, friends who are more "green" than you or don't know anything about cars will definitely look at you with new eyes, especially when they know that your bike is more expensive than a little sheep, they will only have polarized reactions. One is to study your car carefully, and the other is to say that you are crazy. However, no matter what kind of reflection, you will inevitably have some satisfaction in your heart. The second satisfaction is that the quality and performance of the vehicle must be above the standard. As long as you take the time to learn the knowledge of proper maintenance and use, you will find that this is a once-and-for-all method, which can save a lot of money in the process of promotion.

D perfectionism1more than 2000 yuan

Are you sure this is your first time to buy a leisure bike? Either you are a high-income person such as electronic upstart, or you are a perfectionist who pursues perfect texture; I suggest you choose your riding route carefully, improve your riding skills step by step, and more importantly, persevere and consult us regularly. Soon, you will be like a car, entering the expert's field of vision.

Accessories collocation

Now you have become a cyclist, but you have nothing but a bicycle. This way is risky! You must also need some accessories to "enjoy" riding instead of taking risks. The most basic things you need are safety equipment such as helmets, locks and lights, followed by maintenance equipment such as air pumps, spare tires and simple tools. You should learn how to use them in an emergency. Functional equipment such as kettle, car clothes, trousers, gloves, shoes, watches, etc. are essential after the novice gradually advances.

Selection of road vehicles

Judging from Mao Ge's speech, I used to ride a mountain bike, but now I want to buy a road bike, with a budget ceiling of 280,000. To tell the truth, 280,000 yuan is enough to buy a limited edition Ferrari car in Colnago, so what you can buy is not a problem, but what you can buy.

Before choosing a car, Mao Ge must first make clear what the goal of this car is.

Is it a transit car to explore the world of road cars?

Or do you want to build an appreciation-class collection car?

How long are you going to ride to buy a car?

Is cycling a leisurely ride for fitness outing or is it required to ride higher and faster?

Think clearly about the goal, and the result will be clearer.

If old Mao Ge wants to form:

1. To explore the world of road vehicles, C.D. suggested that "a frame with comfortable characteristics and a front fork with good shock absorption" is the focus of frame selection, because just entering the world of road vehicles, the skills and ability of pedal rotation and the power output of muscles are unknown, and it is better to choose a three-disc system with a wide transmission ratio for the braking system than ct or standard systems.

2. Considering the goal of "riding faster and riding higher", the sensitivity of transmission is mainly considered in the selection of frame, and the dual-disc system (CT or traditional) with better speed change efficiency is preferred.

When the budget is not a problem, we must first choose the material of the border. Aluminum, steel, titanium and carbon fiber have their own characteristics and personalities. Many articles mentioned by predecessors are not repeated, only reminding that carbon fiber belongs to composite materials. The word carbon fiber, like the word "car", is a general term. The material characteristics of carbon fiber cars from different manufacturers are different, even different models from the same manufacturer. The frame comparison suggestion is to choose a traditional famous factory, which has a profound experience and unique inheritance for the geometric angle of bicycles. Take Colnago as an example, regardless of the material grade, high acceleration sensitivity and fast transmission speed have always been the main characteristics of the products of this factory.

So how to choose the right frame? First find out whether the main design goals of the original factory match the demand, list the "goals", and then go to the forum to find the owner's comments on the actual ownership of this car. Of course, it is best to have a friend or a car shop to provide a test ride of the same car before buying. In addition, light weight is a good thing, but it cannot be unlimited. The geometric design of the frame has far greater influence on riding than the weight. C.D.' s Colnago Master X-Light all-steel frame, with toothed faucet handle and traditional seat cushion, is much heavier than another steel carbon fiber GIOS, but it always takes Colnago faster to climb the cat's clearing. However, when it comes to long-distance cycling (over 100KM), the comfort and relaxation provided by GIOS are beyond Colnago's reach.

C.D., a two-disk system, prefers Campy series, while Shimano, a three-disk system, is superior to C brand in the efficiency and problems of pre-transformer and large-disk design. According to my experience, the first road bike was steel carbon fiber GIOS. At that time, the riding posture and transmission efficiency of road vehicles were unknown, so the Shimano Ultegra three-disc system in 2005 was chosen as the speed change system, and the flywheel should have used three discs at that time, so 12-25 was chosen! Unexpectedly, it was a complete failure. Climbing ability is at least 20% slower than riding a mountain bike, so we have to fly to 12-27 with the maximum Dura-Ace rotation, and then practice hard to this point. Whether it is climbing in the cat air or fighting in the middle lake, there is no problem. In addition to easy climbing, three sets of wider gear ratios can be applied, such as slow downhill from Pingxi to Taipei and high-speed unicycle riding among friends. The front drive of the three-disk system needs two-stage push-pull action, which is much more complicated than the single-stage push-pull of the two-disk system, and the center line of the chain must be considered. The fine adjustment of transmission system needs more professional knowledge and many adjustment tests to obtain better transmission benefits. As for the weight and beauty of the three-disc system, under the principle of "initial research" of road vehicles, it is not the focus of consideration.

My second transmission system is Campy's Courus standard disk. Compared with Shimano, Campy's rear shift efficiency is accurate and fast, and the narrow grip and steady braking make C.D. feel more popular than Shimano system. But the problem is that it is still difficult to climb the mountain with the flywheel of 13-29 in the 53-39 market, but the transmission ratio is too light to step on when accelerating downhill.

With previous riding experience, I have a certain understanding of personal "moving tooth ratio" and "comfortable revolutions". Because the third car of C.D. is set as a racing car, the recorded CT system is selected as the transmission system, but it is equipped with two sets of gears, one set of 13-29 is used for the mountaineering wheelset, and the other set of 12- is added. In addition to the consideration of efficiency and weight, I also have some understanding and experience in the assembly and adjustment of road vehicles during my "beginner" period. Although I don't have the skills, I can cope with simple adjustment and secondary maintenance, and I can change the equipment at any time as needed.

Lala miscellaneous said a lot, tell the conclusion:

1. The budget is enough to assemble cars, and various parts can be assembled according to requirements. Please choose the S-brand of the transmission system above the second level and the C-brand above the third level, otherwise it will lose the significance of assembling the car. When the budget is low, it is more economical to choose a car and adjust some parts.

2. Easy to use: three sets of > CT> standards.

3. performance: standard > CT> three sets.

4. Easy to adjust: standard > CT> three sets.

5. The higher the part level, the higher the efficiency and the lower the assembly tolerance, and the more important the adjustment technology is.

6. Don't ignore the influence of wheelsets on riding.

7. It is very important to choose a cooperative car shop, and the evaluation of the car shop can be weighted from three aspects: price, professional technology and after-sales service.

How to choose and assemble bicycles

Choosing a bicycle mainly depends on the frame, parts and assembly technology. Only by combining these three factors scientifically can a good bicycle be considered.

First, the framework:

1. What is the framework?

The frame is equivalent to a human skeleton, and only with the frame can various bicycle parts be mounted. The frame is made of iron, aluminum alloy and other materials, and the angle formed according to the length of the pipe affects the characteristics of the whole bicycle. For example, bicycles that ride well in a straight line, bicycles that turn easily, bicycles that ride comfortably, and so on. Many of these factors come from the framework.

2. What is a good framework?

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 the car is loaded with a frame that does not meet the above requirements, it is possible to produce bicycles that cannot ride in a straight line or have difficulty turning, or bicycles that will be retired soon.

3. What material is the frame made of?

Iron frame is the most common, but iron frame is also divided into chromium-molybdenum steel, high-strength steel, ordinary steel and so on. After adding these other components, it can be made into, for example, thinner pipes, making the whole frame lighter. Recently, on the basis of not reducing the strength, a frame made of materials other than iron such as aluminum alloy has appeared. There is a frame made of titanium carbon fiber in cycling competition.

Second, the parts composition

1. What are bicycle parts?

Various parts installed on the frame have their own functions. For example, braking is to stop the bicycle safely; Pedals transmit power to wheels, etc. The professional factories that produce and sell these parts are called bicycle parts manufacturers. Famous parts manufacturers develop new products every year, provide them to major bicycle manufacturers, and then appear in the market.

2. What is the best part of a bicycle?

Simply put, it is light and strong, with good performance. Because of these conditions, cycling is easy, safe and convenient. But to achieve all the above conditions, we need good materials. Therefore, bicycle parts are often a specific factor that affects bicycle prices. It is best to be able to participate in the Olympic cycling competition. The best materials are used in strength, performance and weight.

Third, assembly technology.

1. assembly technology

A good part is not assembled properly, just like a house that has not been carefully designed by an architect and built by an experienced craftsman, it will make you nervous all day for fear of collapse. Therefore, if you don't want to regret it after buying it, you must understand this knowledge.

2. Comfort function of bicycle

A. transmission?

Many people mistakenly think that bicycles are equipped with transmissions to speed up riding, but in fact, the maximum power that people can emit is only 0.4 horsepower. The transmission is just a tool to help people play this maximum horsepower easily.

B. what are the benefits of transmission?

Bicycles are generally used in cities, but there are actually many slopes in cities. For example, sometimes riding a bicycle will make you feel that your feet suddenly become heavy, and there are often many slopes that you can't judge with your eyes. At this time, the role of the transmission can be fully reflected. If you have a transmission, you can ride easily as long as you can change to a lighter gear. Of course, it can also be used against the wind

The advantage of transmission is that it can help you effectively reduce physical consumption in the case of poor physical strength. For example, when you have a cold, don't consume too much energy, so it will be easier to choose a lighter number of teeth when riding a bike than when riding. There are also women who are in poor health, students who are tired of exams, and elderly people who can use variable-speed bicycles flexibly. So the benefits of the gearbox are really too much.

C. In the past, the transmission system needed to be fine-tuned (now some transmission vehicles need to be fine-tuned), but with the successful development of SIS (Shimano Index System) function, many bicycles are equipped with SIS system. When shifting gears, you can change gears with the sound of "snapping", without worrying about how to operate.

D. I don't know what gear I am in when I ride.

Now there is a digital display on the shift handle. Just look at the digital display. The latest product is the electronic display system of flight deck with computer LCD display. The display system can also display 17 functions, such as time, average speed, total riding distance, etc.

E. internal speed change and external speed change

Before understanding them, it is necessary to understand the concepts of inward transmission and outward transmission. Simply put, the external transmission means that the transmission is installed outside the bicycle as a separate part, while the internal transmission means the built-in part hidden in the rear hub.

The external speed change is directly presented to the outside and directly contacts the external space. The internal transmission is hidden inside and does not directly contact the external space. This external transformer is mostly used for mountain bikes because of its large design space and large speed range. However, due to contact with external rain, dust, oil pollution, etc. , must be cleaned and maintained regularly, and the internal transmission does not need regular maintenance. However, due to the limited design space and variable speed range, there are also many light vehicles commonly used for urban cycling.

F. why is it not popular now?

In the domestic market, because consumers have not realized the charm of inward transmission, it is not common at this stage, but it is very common in Japan and developed countries in western Europe (50% of bicycles in Japan are inward transmission). Of course, the reason is that there is no need for maintenance. The latest new product also has a fully automatic internal transmission system, which can automatically change speed through computer induction and micro-motor.

G. the brake is an important part.

The quality of the brakes is related to the safety of you and others. Braking force and braking time are the main factors that determine braking quality, so it is very important to have good braking performance and light operating force. There is a common drum brake in the Japanese market, which can get satisfactory results as usual in rainy days, without noise and maintenance.

What kind of bike suits you best?

First of all, it depends on the purpose of riding. Generally, you can use a light car for work, school and shopping, preferably a relatively large basket, where you can put your schoolbag or something. You can also buy a car with internal transmission or a bicycle with external transmission if you have the conditions.

Cycling on a slope or bridge, if you find it troublesome to climb the slope and get on the bridge, don't choose a bicycle with a transmission.

If the road you ride is uneven and there is no paved road, you should choose wider tires and bicycles with transmissions.

If you ride a long distance a day, choose a bicycle with a transmission and narrow tires. If it's a short trip, you should choose a light car.

If it often rains where you are, you should choose a bicycle with fenders. If you have more opportunities to ride a bike at night, you should choose a bike with lights and the like.

There are many kinds of bicycles in bicycle shops, and their appearances and colors are different, so before going to the bicycle shop, you'd better decide what kind of bicycles you need according to your actual situation, and then go to the bicycle shop to buy them.

Choice of bicycles

Although in college, I would spend hundreds of dollars riding a bike and have a good time, but as a real car player, it is not enough.

There are many kinds of bicycles. It can be roughly divided into road bikes, mountain bikes, track bikes, BMX bikes, skill bikes and so on. Generally speaking, BMX has many similarities with skill cars, skateboards and roller skating, which are very popular among teenagers. For people who travel for the purpose, according to the different places they go, they generally choose three kinds: road car, mountain bike and station wagon.

Road bicycles have narrow and thin tires, light body, flexible and accurate gears and high speed; The mountain bike body is firm, the brakes are dexterous and the shock absorption is good; Tour bikes are between road bikes and mountain bikes. It looks like a mountain bike, but its wheels are thinner and lighter.

A complete car imported from abroad, such as Canondale of the United States, which is highly praised by riders, is often tens of thousands of yuan, which is hard for Chinese people to want. So choose according to your own needs. If it's just the first time you try to ride, a low-end domestic giant brand sports bike around 1500 yuan will do. There are road cars, mountain bikes and station wagons.

Save a bike by yourself.

If you really want to join the car group, you might as well "save" a bike yourself.

When choosing accessories, you need to consider the following factors: the bicycle project you are interested in, your physical condition, the functions you need, the firmness, and of course your financial strength.

Just as computer players can save computers, car players have an "ideal preparation" plan: the frame and rims should be strong. Sports cars are different from ordinary bicycles, and its outstanding requirement is to be strong. The frame must be able to withstand great pressure, impact and vibration without breaking or deformation. The rim must be double-layered, so that the inner tube will not be damaged during exercise. It should be noted that belts should be purchased in pairs (the patterns of the front and rear belts are different, which is the need for different front and rear forces in sports). The performance of the suite is better. "Good performance" is a very common sentence, and everyone who plays with cars will bring it out from time to time. In fact, this is a very vague term, which can represent multiple meanings such as firmness, comfort and lightness. In their words, "it feels good." If you can, try to choose high-grade kits. A set of Japanese-made ShimanoXTR97 kit includes: front and rear wheel shafts, flywheels, toothed plates, front and rear brakes, front and rear zippers, central shafts, brake handles, conduits, chains, etc. It is a relatively high-grade accessory at present, and the price is naturally high. Seats and handlebars should be comfortable.

Bicycle accessories are not as important as big ones, but they can't be ignored. The shape and hardness of the handle cover and the seat should be appropriate, so that you won't feel tired after a long exercise. Although there are so many parts in a whole set of bicycles, their combined weight is only 20 kilograms. The road race is much lighter, only about 14 Jin, so you won't feel very tired when you move upstairs every day.

The cost of assembling a sports bike ranges from several thousand yuan to tens of thousands of yuan. For safety, don't buy a "mountain bike" of several hundred yuan on the street. Those cars will have a good time in a flat city. If you ride to the outer suburbs, you will suffer from bumps.

Loading DIY

Many players will assemble bicycles by themselves, because it is cheaper than buying a whole car, and they can also configure parts according to their own preferences.

In addition to parts, the most important thing in loading is a complete set of tools. Hexagon wrenches, wrenches, screwdrivers, wire cutters ... Special tools need at least one connector.

When the parts and tools are finished, you can start loading. Install the intermediate shaft where you bought it first, because the installation requires special tools, and it is useless to buy this tool when you go home. Beginners had better go to the garage to adjust the wheels.

1. Install the front of the car with five parts. Hit the upper and lower cups on the frame with wooden mats. It doesn't matter if you use some violence here, because the framework is very strong. Similarly, the front fork can be installed on the frame by hitting the wave crest on the front fork and smearing the wave ring diagram. Remember, never reverse the direction of the wave ring. Put the rear wheel on the car so that the car can stand firm.

2. Install the front of the car. Clip the stem to the upper end of the front fork, not too tightly, because there are five pieces to tighten at the back. Clamp the handle horizontally on the handle post, then put the handbrake and lever, dip it in some water and cover it. Pay attention to not too much water.

3. Install the transmission. First, install the toothed disc and tighten the screws. Install the front transmission and rear transmission, and pay attention to the position of the front transmission. Bring the chain, too. Remember that the chain must go through completely, and then change the speed. Put the transmission line on the wave rod, dip a little butter in it, cut off a suitable length of wire sleeve and put it on, and tighten the transmission line to the transmission.

4. Adjust the brake. Install the front wheel and front and rear brakes, and apply some butter to the frame brake seat.

5. Adjust the speed. Install the front and rear wheels, first adjust the low positioning of the rear shift, then change the line after tightening, and then adjust the gear when riding.

Buy mountain bikes

How to choose a suitable mountain bike

Before you want a mountain bike, there are several factors you must consider. What kind of mountain bike do you want to play? What is the approximate budget? Do you want to be a professional player? Or is it just an amateur fitness activity? Here we will introduce you one by one, so that you can understand the different structures and characteristics of various mountain bikes. According to your own budget, choose the cross-country mountain bike that best suits your needs. Under all the conditions, the most important thing to buy a mountain bike is to know whether the frame size is suitable for you. Buying a bicycle that doesn't fit is like buying a pair of shoes that don't fit. It's very inconvenient. Here are three pictures that can clearly tell you how to test whether the bicycle meets your needs.

You can lift the faucet and seat cushion to see if they are waist-high.

When the pedal is pressed to the bottom, the thighs and calves must be almost straight.

When you stand on the upper tube, the height from the upper tube to your pants should be at least 8cm.

Before introducing all kinds of mountain bikes with different functions, let's talk about the budget of buying a car. For the average beginner, we suggest you buy a complete car.
