Bikes are very popular in China. In the city, you can see bikes almost everywhere. When you walk on the road, you can see a lot of people riding bikes to schools, shops and other places. 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 shared bikes with only one yuan every hour. 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. There may be traffic jams because there are too many bikes on the road. We still have much to do to solve the problem, like making strict rules for the riders.
