Bicycle-sharing is a transportation system that allows individuals to rent bicycles for short periods. Users can pick up a bike from designated stations, ride it to their destination, and return it to another station. This service promotes eco-friendly travel and reduces traffic congestion in urban areas. Many cities around the world have implemented bicycle-sharing programs, often using mobile apps for easy access and payment. These systems typically offer various pricing options, including pay-per-ride and subscription plans. Popular examples of bicycle-sharing programs include Citi Bike in New York City and Boris Bikes in London.
