We can see many people riding shared bikes in China now.

    Bike-sharing helps people to borrow a bike from one place and return it at another place easily.

    This kind of bike has GPS or Bluetooth on it. You must have a smart phone if you want to use it. First, you have to download (下载) an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan (扫描) the QR code on the bike and you will get the bike.

    Then you can enjoy your trip. What's more, you can easily find one and don't have to worry about where to park it. Every hour you ride, you need to pay only one yuan. It doesn't cost so much, does it?

    Science changes our lifestyles. Bike sharing makes our life easier. And we also hope that people can not only enjoy it but also put it to good use.
