Now, public bikes are provided for people in many cities in China. I think it's a good thing．
Firstly, bikes are much cheaper than cars and everyone can afford them. Secondly, as we know, there is heavy traffic when people go to school or work. If more people choose to ride bikes, there will be fewer cars and the streets won't be as crowded as they are now. Thirdly, we can ride bikes to keep fit. The most important thing is that riding bikes can help protect the environment because it won’t bring pollution to our environment．
I hope more and more people can ride bikes and live a low-carbon life
