Now, all over the world using more than one billion bicycles, so a bicycle – the most common means of transport. He became one thanks to low cost, light weight, small size, lack of fuel requirements and relative safety.

Types of bicycles:

City bikes are designed for driving in the city, they develop a low speed, but very comfortable. They have a comfortable saddle, good cushioning, speed switches, even if the bike is worth. The only drawback of urban bike is its heavy weight, the main advantage – the safety and easy maintenance.

Road bikes are suitable for driving on asphalt. They may develop high speed, thanks to a narrow tires, thin and light design.

On the mountain bike you can ride on uneven roads, on hills. They often have a lot of speed, wide tires, powerful, heavy wheels, suspension fork steering. Some models have rear suspension.

Hybrid bikes have part of the characteristics of mountain bikes and some of the characteristics of the highway. The diameter of the wheels hybrid bike 28 inches as a road bike, but equipment such as mountain biking.

Travel bicycles are close brothers highway. But they have a stronger body, more reliable design, they can carry heavy loads.

BMX bikes are very popular in recent years, bicycles for competition. Bikes BMX – Bike MotoCross.

Racing bicycles – a version of road bikes, designed for cycling. They are equipped with narrow tires, lots of speed, steering wheel bent downward (ie handlebars are omitted – it creates a great strain on the back of the cyclist, but also reduces the air resistance).

Track bikes used in races for the cycle track. Their task – to develop the maximum speed on level track. From racing, they distinguished by the absence of many “extra” parts such as brakes and gear shifting, and most importantly the lack of free movement of the rear wheel that is fixed gear.

Water bicycles are used for walking. But there is a race on water bikes.

Clown bikes can travel both forward and backward by a fixed transmission is the same as in track cycling.

Three-wheeled bicycles (tricycle) are used, usually young children. There are also adult model for people with impaired balance and other problems. In addition, three-wheeled recumbent bikes often do, pedal cars, trucks bicycles and cycle-rickshaws.
