Kilian Bron a Castaway in Hawaii - Video

 I have to agree with you in some aspects, but if you're getting "beaten up" then you may need to take a look at your surfing etiquette and how you're handling yourself in new lineups.
I've been surfing for over 30yrs(started as a little kid), and riding almost as long. I lived on Oahu and have traveled all over the world to surf and ride. Surfing is getting increasingly frustrating dealing with crowded line ups and inconsiderate surfers and I find myself working harder and sometimes sacrificing wave quality so I can surf alone or with fewer people...but in all this time and random locations I've never been beaten up and generally have had little harassment by locals in new lineups(I have dished out a few words to others that were being dicks and I've tossed out a few apologies if i've accidentally snaked a wave, it happens).
But you're totally right about riding---once on the trails we can find ourselves alone and in as much peace as we desire...total solitude and freedom, and on a regular basis---great form of meditation and resetting the brain.
I'll never quit surfing, but I find myself in the water less these days due to being picky about waves and annoyed if i see too many heads in the lineup, but I know the trail is always there and ready to rip! (and it's great to be able to repeat a trail section multiple times to work out a move or take it faster)

 @andreabonasia I fully agree. Just trying to learn to surf in Australia was so brutal. I would wait my turn, everybody else would get 10 waves and then turn to me and tell me it was cool if I went. then I would just nose dive and get worked because I was essentially not being allowed to learn or practice. If I didn't wait i would get yelled at. Honestly really turned me off to the whole thing

Obviously its not like that everywhere, but it really made me appreciate how chill mountain biking is and how everyone is just stoked to see other riders. pretty sweet

 @GlassGuy Hi buddy! Actually I've never had any issues in the lineup, ever, here in Italy or anywhere else (Cali, Ohau, Spain, France). Maybe a guy once gave me the stink eye in Portugal, but I'm still not sure. Anyway, I think you definitely got my point. While surfing, other people are a problem. When riding bikes, other people are friends.Or just other people. :-)

 mountain biking is rad. you can be on the most popular trail on a holiday weekend and not get in the way of other riders. You might pass a couple people and get passed a couple times but each time its easy unless you have some Strava death wish thing going on. Try saying that about surfing, rock climbing or resort skiing.

 To me, THE big difference is : in MTB you need good (well maintained) trails, but you don't care about the weather, whereas surfing depends on the waves but you never have to pick up the shovel.

I know that's why I'm more into MTB : I can ride whenever I like.

 Put 20 mountain bikers at the top of a trail. Let only 4 ride down. They peddle back up and in a few more minutes let only 4 go again. Each sport has its challenges. Most surf lineups are pretty damn civil and pleasant if you show the most basic etiquette.

 The ocean is a big place surely you could go somewhere else?

 Was just gonna say, that beginning of the vid when he was splashing water on his bike was stressing me out. Gotta love having sponsors.

 The frame is the least of his worries, bearings, linkage and the drivetrain can not look good after that

 You are the kind of guy who said to Candide that it's not so good to ski on leaves and grass
