I really think there isn't a hook for this video. The title is shown immediately and ruins the surprise effect for the hook. I also don't like the discord sound effect that audience would mistake for their own discord. There's also the "Monkey Spinning Monkeys" song overused back in 2014. I really feel like hitting the biker naturally would be a hook. If it was just that, then skip to the next clip of the guy yelling, that would probably be really funny on its own. There's two scenes here but it's shown as one long continuous clip which could also bore the audience and make them skip.
