Erik Roner heads to London to catch up with the Nitro Circus Live crew on this week’s Roner Vision! Mixing it up from the usual ski routine, Erik gets in on everyone else’s action borrowing Lindsay Pastrana’s skateboard to session the Giganta Ramp, pulling a double backflip on James Foster’s BMX bike, razor scooter front flips…turns out Roner is a real jack of all stunts. His closest call with death comes as a spectator, check the BMX impact he takes on the sidelines! Meanwhile back in Tahoe little Oskar Roner has been watching too many YouTube videos and takes Parkour to new levels at the playground! No Oskar!
