Bicycles provide several advantages over cars such as being gas-free, reducing air pollution, and relieving traffic jams. They are also much more energy efficient, requiring around 50 times less energy than cars. Several cities have implemented public bicycle programs to address issues of traffic and parking shortages. The U-bike concept combines bicycles with digital technology and public transportation to provide additional benefits to users.
