Since April 14th, 2014 you are able to use the bike rental system Call a Bike from Deutsche Bahn for low fares. The rental system is a part of your status as a student and similar to the Semesterticket. After you register you can use three bikes as often as you want for one hour for no extra fee. This is not only possible in Darmstadt but in every city where Call a Bikes can be fund. If you use a bike longer then one hour small fees apply.
You get an account with this special pricing model after registration with your @stud.tu-darmstadt.de email address.
You can use Call a Bikes as often as you want for a ride that is shorter then 60 minutes for no extra cost. If you use a bike longer then on hour at a time you have to pay 0,08 € per minute starting with the 61st minute. The average ride is way shorter so this should be a theoretical scenario in most circumstances. You can use three bikes at the same time so you can share the experience with friends who are no students.
This terms and conditions apply for you as a TU student and have nothing in common with the regular pricing model that was published on July 15th, 2015.
