I was hoping Paris could tell use a little about it too. It's got a really gritty but clean feel on it. I saw a photo in another article of a guy to the right holing a boom with a battery pack and the flash over head so he can get a really balanced light (note stong shadows to right of rider but no shadow from the sun) for the rider but there still something else.
Edit I don't know where the sun is but maybe the flash is lined up with is. In other shoots there's two shadows.

 you can see this photos been taken in the background of the video 48 seconds in to get a idea of the setup

 Hey youngfr, what you are looking at is a few easy steps with the right gear. First I was using an elinchrom ranger powered up to 5 or 6 stops held by Ian Hylands as you can see in the video. The sun is a little brighter which causes its dominant shadow. Flash is camera overhead right. From there even if you don't use lights, use Lightroom 4 to make all your global adjustments. Color, tones, split toning, clarity , etc. I will do a blog on the entire process sometime.

 Yea looking forward for it. And see if you can add photoshop editing steps too. I usually experiment with Vibrance option.
