I am the shared bike. I’d like to be on the street to serve for people. They can ride me just via a mobile app. But horrible things happen a few days ago. Several people stole some of us with paying their bills on the app but treated us badly. They broke my saddle and even threw my friends everywhere. We felt angry for which those bad guys had done. Thanks to some kindly people, we received careful “treatment”. Now, you help as well as the whole society’s attention is what we need most. We are designed to help people who are stuck the heavy traffic. We are neither toy nor private vehicles. Please obey the basic rules.
