zwanzig° is the self-help bicycle repair shop at the Technical University Darmstadt. - You've got a problem with your bike, but no way to solve it yourself? You have bought you a new part or parts and want to mount it, but can't do that in your apartment?

Then come and let us help you. zwanzig° has everything that is needed to repair your bike: tools, space and friendly specialized people with tips. Here you can borrow the tools you need, and even operate on the spot.

Important: You get free support; however, no employee of zwanzig° will repair your bike themselves. This is not possible even for liability reasons.

Of course, zwanzig° isn't made for students of the TU Darmstadt only, but is open to all interested persons during the opening hours.

The workshop is located near the Audimax building of the TU Darmstadt on the back towards the old main building (end of Hochschulstr.), you will find a map here.

We are a little short staffed at the moment. If you would like to support our project with your time, just get in touch (there is the possibility of receiving an expense allowance)!

New self-help bike workshop on the Lichtwiese campus

A new self-help bicycle workshop is being built on the Lichtwiese campus in the immediate vicinity of the new tram turning loop.
The containers for this are located in the separate part of Eugen-Kogon-Straße next to the multi-storey car park.

(More information to follow)

Bicycle repair stations

We can also announce that the TU has set up three bicycle repair stations!

So if we are fully booked or you need something outside opening hours, these are available for you. The one closest to the bike repair shop is at the entrance to Herrngarten by the Call-a-Bike station.
There is another one in front of the Welcome Hotel on Karolinenplatz.

Fahrrad: Fit für den Sommer

Das Wetter wird wieder wärmer. Das Semester hat wieder angefangen.

Wär es nicht schön mit dem Fahrrad zur Uni oder zur Kneipe zu fahren anstatt im vollen Bus zu sitzen (oder im Stau zu stehen)?

Packt euer Fahrrad ein und kommt zum Workshop vorbei. Wir überprüfen zusammen die Straßentauglichkeit und machen ggf. kleinere Reperaturen.
