Bikes are very popular in China. In the country, you can see bikes almost everywhere. When you walk on the road, you can find a lot of people riding bikes to schools, shops and any other place. So many people call China “the kingdom of bikes”. In China, many families have one or two bikes.

Compared with cars, bikes have many advantages. First, bikes often don’t need much money. Some Chinese can’t buy cars, but they can buy bikes. They can also use OFO bikes (共享单车) with only one yuan every hour. An app on the phone helps them to do that. Second, bikes are small to park anywhere. But cars need a bigger place. What’s more, they can’t ride bikes too fast. So it’s usually not dangerous to ride.

However, bikes also bring some problems. Some riders don’t follow the traffic rules and some don’t think about others’ safety. So they ride too fast during rush hours (高峰期). There may be traffic jams because there are too many bikes on the road.
