1- Is that a cable cam or great drone work.
2- What is the specific difference between the two bikes, I'm guessing one is a down hill and one is a freestyle of some sorts, is one hard tail?
1. Neither. It's a pretty crazy truck mounted crane camera.
2. The first bike is a short travel, full suspension slopestyle bike. Made for dirt jumps and bike parks. The second bike is a freeride/dh bike. The first bike only has a few inches of stiff suspension, while the second has closer to 8 inches. Obviously made for bigger, gnarlier stuff.
