As I entered senion secondary school,my father bought me a brand-new bicycle.Bicycling is very popular among my classmates.I used to go to somewhere by bus.I had to wait for some m inutes,sometimes half an hour before the bus came slowly to the stop.Now with the bike,I become free because I can go wherever I want to.It is convenient.Even when the traffic jam occurs,I can go through the narrow space.It is also easy to park.But bicycle theft is so rampant that I have to park it in a safe place.Otherwise it will be gone in the twinkling of an eye.
