Task 4
Development of “White Bikes”
In the 1960s In 1999 Now
People in Amsterdam first had the idea for “white bikes”. They wanted to reduce the amount of traffic and pollution in the city centre. They painted hundreds of white bikes and left them around the city centre for people to use. Within a matter of weeks, the bikes had all been stolen and the project came to an end. “White bikes” returned to Amsterdam. This time every bike had a computer tracking
system in it to make it possible to record its movements and you had to use a special card to take a bike. Bike-sharing is
becoming more and more popular in cities around the world, including Chinese cities.
