Nearly all team members of Zedler-Group live bicycle. They work with it and use it in everyday life, in sports or to participate in competitions. It’s this high identification with the product and the active living and working with the bicycle that our customers feel in the daily contact. Bicycles are not only profession for us, but for most of the team members even a vocation and a passion, be it at Institut für Fahrradtechnik und -Sicherheit GmbH or at Gesellschaft der Fahrrad-Sachverständigen mbH (GDFS). The expertise of Zedler-Group was established by Graduate Engineer Dirk Zedler, the publicly appointed and sworn in expert for bicycles and electric bicycles, who communicates this expertise to the bicycle public in many consultings, expert presentations and publications.
