Bikes are still popular in Beijing. Beause it’s not only fast but also convenient. Most students ride their bikes to school and many people go to work by bike.
However, people's life becomes better and better, and many people buy cars. So many people go to work and go to school by car. Because that is much faster than riding a bike. But it makes the air dirty, and makes the road get crowded and so on.
Riding a bike can help us to stay healthy, save energy and riding a bike is also a good way to exercise. The most important is that riding a bike is more fun than taking a car. So riding a bike is my favorite means of transportation.
