People in Amsterdam have been enjoying the benefits of cycling for years. The idea began about 50 years ago, and was first known as “white bikes”. Amsterdam is a good city for cycling because it’s flat and therefore convenient for bikes. There are also plenty of places for bicycle parking and most streets in the city centre have a bicycle path. Because of its convenience for bicycles, Amsterdam has become very popular with cyclists—an amazing 38% of all trips are made by bike. Some people even call Amsterdam “the City of Bicycles”. 2.The group painted hundreds of bicycles white and placed them in many areas around Amsterdam for people to use. Anyone was allowed to take them and use them for short journeys. People would leave the bike in the place where they finished their journey, so that someone else could then take it and use is from there. Soon after, however, problems came up and the “ white bikes” all disappeared—thieves stole them all in a matter of weeks! 3.In 1999, the “white bikes” returned to Amsterdam— this time with a computer tracking system to record their every move! To take a bicycle, you had to put in a special card. The new “ white bikes” were not actually white but painted in bright colours. The bikes were parked at special parking places. Thus people who wanted to use them had to take them to another special parking place near their destination and leave them there. 4.Thanks to the ideas and efforts of many people, like the cycling fans of the 1960s and those who enabled the return of “ white bikes”, you can now enjoy clean air and easy transport in central Amsterdam. 5.Nowadays, the idea of “white bikes” has pedalled its way around the world and there has been a global increase in bike-sharing. 6.In China, more and more cities have their own “white bike” programmes. Both the locals and tourists like to use shared bikes because bike-sharing is a cheap and easy way to save energy, reduce air and noise pollution, and enjoy the benefits of exercise in cities. However, problems can also develop, like the theft of bikes and parking issues. Fortunately, people are trying different ways of solving those problems. Where will bike-sharing go in China?
