The number of refugees coming to Germany increases. Hence, integration as part of a sustainable urban development is of increasing importance. To enhance the mobility and activity of asylum seekers in Karlsruhe and to support their intercultural exchange, the initiative “Bikes Without Borders” rents and re-pairs bicycles free of charge. For its concept, it is now granted the “Im│Puls Oststadt” Idea Award. In this way, the urban de-velopment project “District Future – Urban Lab” of the Karlsruhe Institute of Technology (KIT) acknowledges perceptible stimuli for a sustainable urban life.
