CycleHack is a global movement that brings together diverse people to design, build and test solutions that stop or discourage them from cycling. It is a platform to take action and to make cycling easier, more accepted and appealing. Once a year, people around the world meet to stand up for their town. Wuppertal, known as the most cyclist-unfriendly city in Germany, was one of the 25+ cities that took part in 2015. During lectures and workshops, ideas were exchanged, discussed and translated into design proposals.
