After riding the sb-66 at a bike park for a full day, I can say that it certainly is not held back like a "little bike" would be. It just requires a weird mixture of finesse and hard charging to really feel the juices flowing on it (just make sure you have a short stem). Not to mention it pedals really well.
He had an instructional video on how he does this. Equally impressive. Not to speak for him but I bet this shot took a lot more time and effort and probably waiting than we think.
Nice! Inspirational for sure Brad. I've been experimenting with a radio transmitter on my bar just above the shifter. It works pretty rad and I've got some nice shots but it adds another element in the air...
No substitute for the right gear I guess, congrats!
