joshua boyd is the rider that you saw fall. bits of the lower bearing of the bike in front break apart and smacked him right in the helmet, knocked him unconscious. then you see at about 140 miles per hour, joshua is basically ghost riding as he eventually falls off down the track. >> the way he fell was almost the best case scenario. into the grass and the way he went sliding down. that is just one crazy lucky escape. >> he had a concussion, some memory loss, but other than that he is fine. there's a gofundme page to pay for his motorcycle for an incident that was completely out of his control. >>> from and very professional situation to one very unprofessional situation. back yard fun on this small motorcycle. you can do it, katie. no, you can't. >> oh. >> nailed it! >> no, you didn't it. katie was being highly encouraged to go full out towards this jump. she gave it all that little bike had. got a little bit of elevation. that made her lose her balance a bit. doesn't appear she was hurt. >> let's point out how lucky she is.
