On the campus of the University of Stuttgart in Vaihingen, there has been a bicycle workshop since 2018. Here you can simply come by with your bike and repair it yourself with the equipment provided. During opening hours, there is always a person from the AK Fahrradwerkstatt on site who can help you with words and deeds.
