In 2008, Warden returned to X Games with a BMX Vert invite and proceeded to wow the judges with never-before-seen tricks on vert. Warden has a cool command on the bike flip -- a trick in which he stays upright, while the bike does a backflip underneath him. To this day, no other rider has landed the bike flip on vert.
