    • This device is an improved wheelie skateboard having a substantially flat horizontal portion and an integrally connected inclined rear kicktail portion. The front end of the horizontal portion has a pair of conventional skateboard wheels on a truck having a pivot bolt connected to the axle at the rear of the axle, and capable of swivelling in a conventional manner. The inclined kicktail portion has a pair of conventional skateboard wheels having a pivot bolt forward of the axle and, likewise, capable of swivelling in a normal manner. The central pair of wheels is so mounted as to be incapable of swivelling, either because of the nut on the pivot bolt (of a conventional truck), which is to the rear of the axle, is so tightened, or because a horizontal arm portion on a non-conventional truck extends from the truck rearwardly of the axle to forwardly thereof, so that such pair of wheels may tilt but may not swivel.
    • 该装置是具有基本上平坦的水平部分和整体连接的倾斜后部后部部分的改进的轮式滑板。 水平部分的前端在卡车上具有一对常规的滑板轮,其具有连接到车轴后部的轴的枢转螺栓,并且能够以常规方式旋转。 倾斜的推杆部分具有一对常规的滑板轮,其具有在车轴前方的枢转螺栓,并且同样能够以正常的方式旋转。 中心的一对车轮被安装成不能旋转,或者因为位于车轴后部的枢轴螺栓(传统卡车的)上的螺母被拧紧,或者因为水平臂部分 在非常规卡车上从卡车向后延伸到其前部,使得这对车轮可以倾斜但不能旋转。
