recently in China,there are a lot of shared bicycles put at both sides of streets of big cities,like HangZhou and Shanghai. I do not know when shared bicycle apears,but it becomes popular among yong people around the cities.as far as I know,once people pay 199 yuan for cash deposit in official app,they could use it to scan QR code and get the number key of a shared bicycle,and then unlock it.when you starts to ride the bicycle,then it begins timing.it cost you 0.5~1yuan per hour,in which different company not the same.and later when you end up your riding,do not forget to lock the bicycle and pay for it on the app online.

it is a great idea to put shared bicycles in China,but I think it is too early to to it.the people do not care about the bicycles and ofen demage them.somebody even unclear the QR code so that other people cannot scan the number,which make the bicycle private and totally donot conform to the purpose of sharing.therefore,there is still ?a long hard time for shared bicycle company to deal with it.
