City bike-sharing schemes have become a common sight in many large cities around the world. The basic idea is simple: bicycles are left at docking stations across the city, and people can borrow one, ride it to another station, and leave it there. Most systems require users to register before their first trip, either online or at a kiosk. After registering, riders unlock a bike using a mobile app or a smart card. The first thirty minutes of a trip are usually free, and after that the cost rises in small steps, which encourages people to make short trips rather than keeping a bike all day. The benefits of bike sharing are widely reported. First, it provides a cheap and flexible way to travel short distances, especially for journeys that are too long to walk but too short for a car or a bus. Second, it reduces traffic congestion, because every cyclist is one less vehicle on the road. Third, bikes produce no exhaust fumes, so they help to improve air quality in busy city centres. Many city governments therefore support these schemes and pay part of the running costs. However, bike-sharing programmes also face challenges. Some users do not return bikes to stations, and others leave them parked in awkward places, blocking pavements. Vandalism and theft are also problems in some cities. To deal with these issues, operators track every bike using GPS, and users who lose or damage a bike may be charged a fine. Some newer schemes do not use fixed stations at all; instead, users can leave bikes anywhere within a certain area, although they often have to pay extra if they leave a bike outside that area. Cities that have introduced bike sharing have noticed that it works best when it is connected to public transport. A rider might cycle to a railway station, lock the bike, and continue the journey by train. For this reason, many operators place their docking stations near train and bus stops. In some places, the same smart card used for buses and trains can also unlock a hire bike, which makes the whole journey simpler. Overall, bike sharing is not a complete answer to city traffic problems, but it forms a useful part of a modern transport system. It is cheap, clean, and healthy, and it gives city residents another way to move around without owning a car.
