A daredevil is being hailed as the first BMX rider to complete a successful quad backflip.

New Zealander Jed Mildon rode the bike and did four backflips off a 21-foot-tall box jump on Sunday in Maryland at the motorsports park Pastranaland (named after stunt performer Travis Pastrana).

In an interview with Ride BMX Magazine, he said the stunt was the culmination of nine months of “physical” training and four years of “mental” training. In the footage aired by NBC, he seems to have pulled it off without injury, which is an especially impressive feat considering fellow BMX rider James Foster broke ten ribs and endured a separated shoulder while training for his attempt.
