With Bike2Boat, Redbull athlete Adrian Mattern and Brendon Orten have teamed up with kayak legend Olaf Obsommer and videographer Jens Klatt to travel by kayak and mountain bike from Innsbruck across the Alps without carbon emissions. Their faithful companion: the reacha bicycle trailer. Starting in Innsbruck, they cycled 800 kilometres for 21 days and paddled 9 different rivers and always with them: the reacha SPORT.
