How do you think about riding your bike to school?

I disagree about this statement as well.

Everyone knows that the bikes are expensive but also the bus bill is expensive too. However, it is very dangerous to ride come and back by a bike to school everyday. Perhaps, many students are getting hurt cause by a riding bike in small street and have a accident with a car hit because they are in square zone which the drivers can't see us clearly. For instance, in statistics in 2000, the 5grades are only 13 persentage which the 1grades are 27 persentage of all in ability in stamina but over 2007, the world's technology upgraded so 1grades are decreasing fastly so the government made a system that over middle school, we must make PE class and have it 5 hours a week.

So I must plan this well that I hope the world change against our stamina that I disagree about it because walking is better.
