Good video, as usual. He asks the tough questions and really tests things out properly. Makes a nice living from these videos, as far as I can tell.

As for the stunts, he's primarily a mountain biker; the kind doing jumps and such. I think that, combined with having grown up a hooligan kid on a bike explains it. Spice things up a bit, in other words.

He says something to close all his videos that I think makes a good point; something like: "I hope you found this video informative, and if not, then at least entertaining..." He strives to entertain and inform. More viewers that way, maybe?

He has done a series of videos where he visits different cities to rate them for bike-ability, and part of his format is to do something sketchy in each city. Some jump here and there.

You may see less of it going forward, as he's getting older and it hurts more and longer when he crashes doing sketchy stuff.
