It looked like maybe a crank or shaft broke? Maybe a chain? Looks like he was standing on the pedals and then dropped, and then he just coasts after that. Right before he flings it, I see maybe a chain dragging? He seemed to be mad at the bike, not the car behind him.
Wonder if that'll make it in the bike ad?
