This working paper seeks to provide decision makers at the city level a series of frequently asked questions and responses in order to assess the adoption and implementation of bike sharing. It is not designed to be a comprehensive guide to bike-sharing implementation, nor is it meant to provide prescriptive recommendations; rather, it offers questions and answers objectively in order to assist city officials to navigate through the recent developments and innovations of new and improved technologies, data, and business models relating to bike sharing. The emergence of new technologies, including dockless and electric bikes, is creating new opportunities, so much so as to raise the interest and risk concerns of city officials around the world. This publication aims to shed light on these.
