Earlier this year I travelled to California with Matthias Dandois and Maxime Charveron, as part of French mobile phone provider Sosh’s ‘Couchriding’ trip. With a massive crew of two riders, two skaters, one snowboarder, two photographers, three filmers, assistants and journalists, it was hardly your typical BMX trip, but it turned out to be an insane experience. Here’s a selection of mostly unseen rider related shots from what turned into an epic photographic journey. - Vince Perraud
