When the guy goes over the bars and continues swimming.. awesome I'd love to try one of those bad boys.
I've said it before, and I'll say it many more times: I LOVE my Surly Krampus 29x3. Splits the difference between a faster trail bike and a fatbike. I'm convinced it cruises most trails as fast as a comparable dual-suspension. In fact, my son's outgrowing his 20" 1-speed, and I really have my eye on one of these little Specialized fatbikes. Will make trails much easier on an inexperienced rider.
I saw a test this year on Youtube and indeed both a conventional MTB and a Fatbike had similar "laptimes". But the big tires look so much more fun
