What is the bmx trick the truck driver?

Answer 1

A truck-driver, in the realm of bicycle dirt-jumping, is an aerial maneuver that merges a bar-spin with a 360. Typically, the rider (and bicycle) begins a 360 spin, and gives the handlebars a nudge in the opposite direction of the 360, and lets them spin. The handlebars should complete a full revolution before being caught by the rider, who, at that point has nearly completed a 360-degree revolution. Just prior to, and for the duration of the handlebar rotation, the rider pinches the bicycle's seat using his knees. This is an advanced maneuver; variants include a half-truck, which is accomplished by completing a 180-degree rotation while the handlebars are spun either a full revolution, or are rotated 180-degrees in a hand-off from one hand to the other. This has been incorporated in mini-ramp/park riding with the abubuca; the rider completes the maneuver, landing with a pronounced dwell on either the front or rear wheel, using either the brake or a foot to restrain the grounded tire from rolling, prior to dropping back into the ramp.
