We have to admit that we live in an ego of "sharing". The shared resource, shared network and shared knowledge have played an important part in our life though few of us noticed the huge transform. With the prevailing usage of shared bikes at the end of 2016, a new member joined the "shared family".

Among the numerous bike-sharing companies, Mobike and Ofo dominate a large segment of the market and the two of them have succeeded in plunging into overseas markets. Why do shared bikes grow so fast? I think I should attribute the main factor to its convenience and efficiency. We can finish the loan and return of shared bike just by using a mobile phone app. What's more, shared bikes have obvious advantages in environment-protection and the relief of traffic pressure. Furthermore, the fare for loaning a shared bike is low and acceptable for most of the people.

However, there are also many problems needed to be solved as quickly as possible for bike-sharing companies. For example, many people park the shared bike in a casual place or even hide it in their own houses. Moreover, the major users of shared bikes are young people because the old man has poor knowledge of smartphone.

In a word, a better future for shared bikes needs our joint effort.
