Many years ago, bike was very popular among teenagers, but as the development of economy, few kids ride bike and most of them are driven to school by their parents. Recently, as the Ofo comes into the market, which reminds of people the simple lifestyle. A lot of people ride these yellow bikes on the street. What a beautiful picture. I love riding bike so much. It is such leisure. I can do the exercise, at the same time, I can appreciate the scenery. Sometimes riding bike makes me feel like in the movie, enjoying the leisure lifestyle as the heroine. No matter how the world changes, I think bike will be part of my life.
