Roland Kloss was born in Linz/Austria, studied Environmental System Sciences and Geography in Graz and Urban Planning in Vienna, with exchange semesters in Kamloops/British Columbia and Bordeaux/France. He worked as an expert for integrative urban energy planning in the Energy Center Vienna. At present he works in the urban planning office Kampus in Graz.
Ewa and Roland got to know each other at studying Urban Planning at the Technical University of Vienna. Their passion for cycling led into the foundation of the NGO Crossover – cyclists create cities for people to promote urban cycling. They carried out a campaign for bicycle-friendly urban development in 14 countries in Europe. With a selfmade bamboo tandem and several event formats they connected stakeholders in 28 cities to establish a cooperation between citizens and public authorities to create cities for people. As a symbol of communication between bottom-up and top-down levels they made 30 mayors ride their bamboo tandem together with citizens in one direction and asked them: How do you get people on bikes? What is the future of urban mobility?
After the big tandem crossover tour 2016 they settled in Graz/Austria, where they advocate for bicycle-friendly urban development and run the crossover network.
