In 1990, Andi Heckmair set off from his house in Oberstdorf with the aim of crossing the Alps by bike. At his side: The world's first bike backpack, designed by Andi Heckmair personally and implemented by Deuter: the Bike I. At that time it had 24 liters, was simple and light, and already had a ventilation system for the back. To date, we have retained the tradition of the backpack, and have improved a lot over the years. In the heart, however, the Bike I has always remained a Heckmair design - developed for the first transalp by mountain bike.
