Many people travel by car or by bike in our daily life, to be a student, I think it is better to travel by bike. First, when we ride a bike to school or to work, it doesn't make any pollution, at the same time, it is a kind of sports, riding a bike can make us strong and healthy; second, there are too many cars in the street at busy time , if I ride a bike, I can ride on the narrow street, so it is very fast, so I like riding a bike.
