Bicycle-sharing schemes (BSSs) are experiencing a major breakthrough in cities at a global scale. Of the estimated 1,600 schemes in operation in 2017, approximately 95 percent were launched since 2007, with more than 200 in 2017 alone. Recent technological transformations and innovations are dramatically reshaping our cities and increasing their options to introduce and manage bike-sharing services as a new mode of transport. The rapid evolution of technological advancements in BSSs, such as dockless bike-sharing schemes, electric bicycles, and increased private sector involvement, areprompting cities to ensure that legislation and regulations are in place to adequately safeguard the efficiency and safety of this mobility option. To ensure a safe and sustainably integrated urban mobility network including a BSS, it is essential for local governments and bike-sharing operators to work together. The role of public-private partnerships can be important in any public mobility service, particularly in terms of bike sharing. City administrators and private entities must work together to develop appropriate legislation, provide adequate infrastructure, and manage the operation and maintenance of the service. To ensure success, the key factors are the scale of and access to BSSs, whereby bike sharing should be at a scale that corresponds to the size of the city and is easily accessible to achieve ridership.
