Classification of bicycle

　　Ordinary bikes

　　Generally refers to the car, the riding posture is the bending leg standing type, the advantage is the comfort high, long time cycling not easy fatigue. The disadvantage is that the bending leg posture is not easy to accelerate, and the ordinary bicycle parts often use very ordinary parts, also difficult to achieve high speed.

　　Road bike

　　For use on smooth road surface type, with smooth surface resistance is small, the design of road bikes more considerations high-speed, often use can reduce the wind resistance of the curved handle, narrow the high pressure of low resistance and high gear, and wheel diameter is larger than the general mountaineering suvs, due to the frame and accessories need not be like a mountain bike needs to strengthen, so the weight is lighter, often ride on the highway when the efficiency is very high. The road car is the most beautiful bike because the frame is not reinforced and often simple and efficient diamond design.

　　Fitness bike

　　Health, fashion, new concept design of the new concept of fitness bike, the most important feature is the hands and feet double power, speed can reach 40km/h; Many ways of doing work, good health effect. While riding this bike, the hands and feet can work on the bike, or it can be driven by hand or foot alone. The use of foot-dragging and hand swing swing is used to improve the speed of the bicycle and the muscles of the legs and arms. A number of national patents have been obtained, which can be adapted to the use of transportation tools for middle-aged and elderly people, as well as for young people.

　　Ground bike

　　The bicycle used for the extremely smooth elliptical track in the house, which has no brakes (brakes), no transmission, and no reversible flywheel.

　　Triathlon/Time Trial bike (Triathlon/Time Trial bicycle) in the Triathlon and Time Trial use of the road cycling, Triathlon and the biggest characteristic of Time Trial is not allowed to use drawing airflow (draft), in other words contestants must entirely by his own strength to overcome air resistance, and are not allowed to ride in the back of the other players, so a Triathlon/Time Trial bike very pay attention to keep players in the design of a cycling posture, reduce the air resistance at the same Time pay attention to reduce the bike itself air resistance. The triathlon also allows riders to use similar muscle groups while riding, which makes switching from cycling to running easier.

　　Mountain bike

　　Mountain bikes originated in San Francisco, USA in 1977. Design for riding in mountainous areas, usually has a gear transmission can transform energy or quickly, some will be installed in frame shock absorbers, part of the tire skin is chocolate tire shop so that in the absence of bike riding the pavement. The size of mountain bike parts is generally English units. The car ring is 24/26/29 inches and the tire size is generally 1.0-2.5 inches. The frame size is also in English, such as 14", 17" and 19" to indicate the size of the frame. There are a lot of categories, and we typically see the xc class. Variable speed, the tire rough grip is suitable for off-road, the shock absorption system reduces turbulence. Strong overall strength and strong impact resistance. It's more difficult to damage than a normal bike.

　　The downhill bike

　　Downhill bike, also known as mountain bike. It's called DH. It's a very challenging activity. Riders use a special DH bike to glide over a hillside, even falling down to seek excitement. The activities are mainly carried out in mountain ranges, mining caves and snow fields. The austrians used DH to create a world record of 210.4KM/H. The Angle of the bike frame is different from that of mountain bike, and the parts are the same as mountain bikes. To carry out this work, you must wear a helmet, armor and other equipment. The front fork is longer than the mountain bike and the XC bike. The tyre is generally more than 2 inches wide.

　　Children bicycle

　　Children's bicycles are also known as children's bicycles and children's bicycles. China, Taiwan and Singapore are commonly referred to as "children's bicycles" or "children's bicycles". In Hong Kong and Macao, it is often referred to as "children's bicycles". Children's bicycles are one of the main categories of children's bicycles, including children's bicycles, children's carts, baby walkers, children's tricycles, and so on.

　　Bike trip

　　Developed by the road cycling, suitable for remote self-sufficiency of travel, have a comfortable and relaxed frame geometric design, affordable, can have very low minimum gear, using the wide tires, accessories selection pursuit of reliable and durable, less weight, on mountain bike pedals are often used. It evolved for the hills. Most of them are the same but have more flexible configuration. For example, the car can be changed into butterfly shape and can be used in many ways to reduce the fatigue in a long time. The front fork can also be installed with shock absorption or shock absorption. The wheel can be 700c or 26 inches. But the brakes are usually v brakes. It can be conveniently loaded with shelves, tiles, and camel bags. In short, all changes are made to increase durability and reduce fatigue in the long run.

　　Dead flying bicycle

　　Die coaster originated in cycling, flywheel is fixed, on the car forward, forward backward step on the car back, there are some alternative work cyclist using abandoned the site of the car as a traffic tool, it can travel fast in cities, and the price is low, and needs certain cycling techniques. These features made it popular among cyclists in countries such as Britain and America, and became a street culture. The bicycle brands have also been followed up to develop and promote the dead flying cars, making them popular among the public and becoming the most popular bicycle styles in the city. Pure dead flying cars require certain technology and are dangerous, so the products developed by these manufacturers are both dead and live, and equipped with brakes to ensure safety.

　　More than a bike

　　Also known as a tandem car, the two or more people work together, from the first control direction. It is used in tourist attractions for lovers, families and friends.

　　Folding bike

　　It is designed to carry and fit into the car, and some local public transport vehicles such as railway and air travel allow passengers to carry a bicycle that can be folded and folded into a bag.

　　BMX

　　Also known as BMX, split flowers, street type, soil slope and many other kinds of play are different, and this picture is not BMX is a conceptualized climbing bicycle.

　　Technology of car

　　Technology car a specialized for extreme sports bike, which makes a lot of modification in order to more suitable for stunts, such as a lightweight but sturdy abnormal body, no transmission, no implantation, even remove the brake mechanism.
