?。?）Shared bikes entered Shantou in February this year. They have been used widely since then, especially by the young. Some ride shared bikes to school or to work during the rush hour. Others may ride them to exercise or just for fun.
In my opinion, it’s really convenient to use shared bikes. It’s also a green and cheap way to go around on a shared bike. As users, we should always follow the rules. It’s our duty to take care of the bikes when using them. What’s more, please remember that children under 12 shouldn’t be allowed to ride a shared bike.(94w)
Recently, a new kind of bike called the shared bike has appeared in many cities in China. Shared bikes are easy and cheap to use. First, you download the app of a shared bike onto your smart phone. Then when you want to unlock and ride a bike, you just scan the two-dimensional code(二维码) on the bike with your smart phone. The GPS-supported app helps position the bikes no matter where they are parked. And they can be left in public places for the next users. If you need a bike, you can easily find the nearest one through the app. A 30-minute ride costs only 0.5 to 1 yuan.
Among different kinds of shared bikes, Ofo and Mobike are the most popular ones. It is said that in the first week of this year there were 585 million active users of Mobike and Ofo had 1.4 million users. Ofo, which got its name from the look of a bicycle (ofo), was first used by students in Peking University and soon became popular out of the university.
“In places where the subway doesn’t get to, or places where it’s difficult to change from one kind of transportation to another, it’s easy to get where you want to go with a shared bike.” said Hu Hong, one of the users from Shanghai, “But following the service, rules must come first before everyone can use it easily.”
