Where did the idea of “white bikes” come from In the 1960s, a group of cycling fans came up with an idea. They believed that it would be better for everybody if cars weren’t allowed in the city centre and only bicycles were. They were hopeful that this would help to save energy, reduce pollution and provide free public transport. 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.

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.
