Docked bicycles in Gothenburg, Sweden

A bicycle-sharing system, bike share program, public bicycle scheme, or public bike share (PBS) scheme, is a shared transport service in which bicycles or electric bicycles are available for shared short-term use by individuals at low cost.

These systems are designed to provide an affordable, flexible, and environmentally friendly mode of transport, often serving as a "first- and last-mile" connection to public transport and helping to reduce traffic congestion and emissions.

Modern bicycle-sharing systems typically operate as either docked networks, where bicycles are rented from and returned to fixed stations, or dockless systems, which use mobile technology and GPS to enable more flexible pick-up and drop-off. Advances in technology since the 2000s have enabled rapid global expansion, with thousands of systems now operating in cities worldwide.

Bicycle-sharing systems originated in grassroot efforts in Europe in the mid-1960s. By 2022, bike share schemes were offered in approximately 3,000 cities worldwide, including Dubai, New York, Paris, Mexico City, Montreal and Barcelona. Today bike-share systems have become an integral part of urban mobility strategies in some cities, offering social, environmental, and health benefits while complementing public transportation networks. They can improve accessibility and equity in urban transport, reduce greenhouse gas emissions and air pollution, and promote physical activity, contributing to better public health outcomes.

Bicycle-sharing systems have also faced challenges, including bicycle theft and vandalism, uneven distribution of bikes, high operational and maintenance cost, and regulatory concerns over urban clutter, particularly with dockless schemes.
