The 4th generation of bike-sharing, also known as dockless- and free-floating bike-sharing is a new type of bike-sharing system. It allows users to start and end their rentals anywhere in the service area. In the spring of 2018 Mobike started their services in the city of Delft. This research is set up around data collected in Delft about the usage of Mobike that contains almost 150.000 trips. A collaboration model between local government and bike-sharing operator is proposed that is based on trust and sharing data. An improved version of dockless bike-sharing based on virtual docking zones is presented that tries to maximize the benefits while minimizing the negative side effects.
