Bike-sharing has swept across China, with an increasing number of people choosing bike riding instead of driving. The bike that the service company provides has GPS or Bluetooth on it, and those bikes can be easily unlocked with a smart phone and left anywhere in public. Bike-sharing allows people to borrow a bike from one place and return it at another place easily.

In some cities, we can see more and more people riding this kind of sharing-bikes. It’s very convenient to use the bikes if you have a smart phone. First, you have to download such an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan the QR code(代码) on the bike or connect your phone with the bike over a Bluetooth wireless connection. You will find the bike can be unlocked itself. Then you can enjoy your trip. What’s more, the greatest advantage of bike-sharing is that you can easily find one and never worry about where to park it. The cost of riding depends on the time that you spend. Normally, every hour you ride, you need to pay one yuan. It doesn’t cost so much, does it?

At the same time, some people park the bikes in their own homes. Besides, some people don’t value the bikes. Now service companies are trying to solve the problem like being stolen.

Technology and science have changed our social lifestyles. We have to say bike-sharing brings us more convenience without doubt. And we also hope that people can not only enjoy it but also put it to good use.
