Nextbike
As a student at the TU Dortmund you have the chance to use the bike-sharing service Nextbike for free in the whole Ruhr Area. You only have to install the app „Nextbike“ and register with your TU-Mail address. Wait for the confirmation mail and let’s go! The rent time is limited to one hour per rent. But you can rent a bike as often as you want on the day.
You find Nextbike stations at the campus nearby the AStA (EF50), at the HG2, at the OH14, at the H-Bahn station „Technologiezentrum“ or at the S-Bahn station „Universität“.
