Bicycles are a good means of transportation for students.So I think students should ride bicycle to school. In my opinion, there are three main reasons for it. First of all, riding bicycle like doing exercise. Everyday, riding bicycle four times to school and get home is the same as one hour working out. Secondly, bicycle is smokef-ree. This really helps to protect our environment. Finally, riding bicycle helps us to save much money. A motor-cycle cost tens times as much as a bicycle. And a motor-cycle needs petrol to work, on the contrary, a bicycle does not needs so riding bicycle to school is a way to save petrol, save money, save natural resources and protect environment. I know that going to school by motor-cycle shows grade for the rider but i think it is not necessary and riding bicycle is all better. Since the reasons i have given to you, i strongly recommend that we should go to school by bicycle instead of motor-cycle.
