Road bicycles, mountain bicycles and leisure bicycles constitute three categories of bicycles. Road bike refers to a kind of bicycle used on the road surface (or artificially hardened road surface or gravel road surface), which can be used for road bike racing. In order to ride at high speed, the car body is lighter and the wind resistance is smaller.

The basic characteristics of this model are:

1. The tires are narrower than ordinary bicycles, and the tire pressure can reach more than 100-200 psi (pounds per square inch), so the rolling resistance when driving is much smaller than that of mountain bikes.

2. The tooth ratio between the toothed plate and the flywheel is very large, which can reach 53: 1 1 or even higher.

3. New materials are widely used, such as titanium alloy, carbon fiber and advanced aluminum alloy, so the weight of road bicycles is very light.

4. Generally, tires are made of very hard materials, which is convenient for athletes to exert their strength.

As for the brand, you can ask the riders around you to help them choose the vehicle. Prices range from 1000 yuan to 10000 yuan, depending on your own economic strength. Generally speaking, about 3000 yuan is enough for daily use.
