The 2 step move you guys are talking about here is what we call a "touch up" here. The secret to this move, is to roll your front wheel on the corner of the obstacle, instead of hitting the side of the obstacle (which is called a tap).

To do the touch up technique, you must throw your body forward with more force than a tap. This movement should happen as soon as you start your second pedal stroke (back foot). you will need to stay crouched with your upper body until the front wheel touches the corner of the obstacle. Then you need to finish your last pedal stroke, push down on your front wheel, and jump.

Here is a short video showing the difference between a touch up and a tap. At the moment where my front wheel hits the rock, my body is much lower for the touch hop, where as i am standing upright for the tap.
