["Bicycles used to be the dominant means of transportation in China’s cities and countryside, and the nation was once called the “Kingdom of Bicycles”. Today, bike riding is gaining popularity again as traffic jams and air pollution become increasingly serious in cities. Recently, Chinese entrepreneurs have invented a business model called shared bikes by combining mobile Internet technology with traditional bicycles. The emergence of shared bikes makes cycling all the more convenient. People can use these bikes at any time with just a cell phone at hand. Many cities have built bicycle lanes to encourage people to travel by bike. Nowadays, more and more Chinese people also prefer to keep fit by riding bicycles."]
