Should people ride their bicycle on the sidewalk or in the street? I think people should ride their bicycle in the street, for two reasons. First of all, there is a risk that people will cause on the sidewalk. Second, it will make a chance people realize that riding bicycle is very dangerous. The reason why there is a risk that people will cause an accident on the sidewalk because If people are riding bicycle on there, they often cause accident with walking people. So, If government will make a rule of people riding bicycle only in the street, an accident will decrease. The another reason why it will make a chance people realize that riding a bicycle is very dangerous because it is not realize always ride a bicycle on the safety situation. So, if people are ride their bicycle on the danger situation, they realize that riding bicycle is very danger. Of course some people feel riding a bicycle in the street is danger. But I believe that the system of riding a bicycle in the street will have good effect on people and environment around them. In conclusion, I think people should ride their bicycle in the street to decrease accident and realize people riding a bicycle in the street is danger.
