Bas Keep quarter pipe action clip
Watch Bas Keep ride the biggest dirt quarter pipe ever built.
British BMX rider Bas Keep has built and ridden the biggest dirt quarter pipe ever made: at 26 feet, he's been reaching heights of more than 45 feet.
Towering at twice the height of a double decker bus and taking around four months to complete, 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. Bas comented:
I’ve always said I wanted to do something like this, I just thought it would be really fun. I remember scribbling down a drawing years ago, with tiny stick people and a double decker bus and, although it is strange seeing your dream become a reality, it’s exactly how I’ve always pictured it.
The quarter pipe was shaped by fellow rider Kye Forte and built by Dan Atherton and a team from Revolution Bike Park in Llangynog, west Wales. Fellow riders Ben Hennon and Ruben Alcantara joined Bas to ride the quarter. Speaking after riding it for the first time Bas said:
At some point most riders get into dirt jumping because it’s simply good fun to build something yourself and then ride it. I hope people see the footage and think, I want to ride that.
