With the urge to reduce car use, shared micro-mobility services like electric kick scooters and electric bicycles can be an appropriate alternative means of transport to cars for short distances. In combination with public transit, sharing micro-mobility schemes provide an area-efficient and flexible means of transport. Especially on the outskirts of a city or smaller towns, sharing micro-vehicles can serve as a feeder to local train stations. In the process of implementing those sharing schemes into the existing transport system that uses mostly narrow sidewalks, the requirements of various groups of interest play a crucial role in this integration. Hence, there is still a gap in research in terms of collaboration between providers and municipalities, especially when implementing the shared micro-mobility service in a municipality for the first time. Hence, this paper investigates which requirements are necessary for both parties as pivotal key factors for a functioning and socially accepted shared micro-mobility service. As part of a living lab approach, multiple station designs and pricing as well as different vehicles (e-kick-scooters and e-bikes) were tested over a period of nine to eleven months between 2022 and 2023 on the outskirts of Berlin. By conducting seven expert interviews with the relevant stakeholders, important findings could be derived. Based on seven expert interviews with the relevant stakeholders, important insights were gained. A dense network of stations located close to public transport is seen as useful for integration into public transport. A lack of communication before and during implementation can jeopardize acceptance.
