As is shown in the bar chart, the number of person aged between 20 and 29 accounts for 44.6% in using bike, ranking first when compared with other age groups. The number of person with the age between 30 and 39 is 35.17%. And those who are beyond 40 years old seem less likely to use bicycle, especially for the ones that are more than 60 years old, with the number of less than 0.8%.
    Basically, two reasons can explain the phenomenon above. Firstly, people aged between 20 and 29 are mostly young workers and students. With the increasing of traffic jam, it is more convenient for them to go for work or study by bike, thus easing the traffic pressure and protecting the environment. Yet people beyond 50 years old are mostly retired workers. There is no need for them to ride bike for work. Secondly, riding a bike has become a fashionable thing today, which can be accepted more easily by young people. The old need both the energy and skill to ride a bike, which seems very difficult for them.
    From where I stand, riding a bike is beneficial to our body and mind. It is also good for the development of a modern society.

    参考译文
    如柱状图所示，在使用自行车上，年龄在20到29岁之间的人数占44.6%，与其他年龄阶层的人数相比排名第一；年龄在30到39岁之间的人数占35.17%；年龄在40岁以上的人较少使用自行车，尤其是那些60岁以上的人，其人数少于0.8%。
    大体上，两个原因可解释上述现象。第一，年龄在20到29岁之间的人大部分是劳动者或者学生。随着交通拥堵问题日益严重，骑自行车去工作或学习对他们来说更方便，由此减轻交通压力并保护环境。然而，年龄在50岁以上的人大部分是退休工人，对他们来说骑自行车没有必要；第二，当今骑自行车已变成一件时尚的事情，年轻人更易接受。老年人骑自行车需要精力和技巧，这对他们来说很难。
    我认为骑自行车有益身心，其对现代社会的发展也有益处。
