Around the SauerlandRadring and the HenneseeSchleife, a number of bus routes operated by Regionalverkehrs Ruhr-Lippe ensure that you can easily get to one of the e-bike rental stations along the route, even if you are staying in one of the neighboring municipalities. And you can simply give your own car a break - a very convenient way to achieve sustainability.
Further and up-to-date information can be found on the website of the RLG.
