In this clip, Bas is joined by Ben Hennon and Ruben Alcantara as they reach heights of more than 45 feet on a BMX. The project took around four months to complete, and the idea to build the quarter pipe came to Bas around five years ago when he approached Red Bull with a sketch drawn on a piece of paper.
