A power application device (PAD) (10) designed to operate in combination with a four-wheeled vehicle (110) such as a skateboard (112). The PAD (10) includes an attachment tube (12) having a front end (14) and a rear end (16). Between the front and rear ends (14,16) are located a front body support (32) and an optional rear body support (38). To the front end (14) of the attachment tube (12) is attached a handle bar (22) and to the rear end (16) is attached a drive wheel (90). The drive wheel (90) is rotated by a drive-wheel powering means (40) that consists of either a d-c motor (50) or an internal combustion engine (80). The motor (50) or engine (80) is operated respectively by a variable resistor (56) or a throttle control (86) located on the handle bar (22). To operate the PAD (10) a rider stands on the skateboard (112) and the PAD (10) is activated causing the drive wheel (90) to rotate, thereby causing the PAD (10) to move forward in unison with the skateboard (112).

1. A power application device (PAD) that interfaces with a PAD rider and an external, foot-operated wheeled vehicle, comprising a skateboard having a two-wheeled front truck and a two-wheeled rear truck said PAD comprising: a) a main frame or attachment tube having: (1) a front end, a rear end, an upper surface and a lower surface,(2) a circular cross-section, a rectangular cross-section or a laminated cross-section,(3) a front end that is elevated from the rear end of said attachment tube to compensate for the height of the PAD rider, and(4) a right or a left body curve that extends horizontally around the side of the PAD rider,b) a handle bar having a right grip, a left grip and a center section having a post that is inserted into a vertical post sleeve located on the front end of said attachment tube,c) a front body support that is adjustably attached to the upper surface of said attachment tube rearward from said handle bar, andd) a drive wheel that is rotatably attached to the rear end of said attachment tube, wherein said drive wheel is rotated by a drive-wheel powering means that is controlled by the PAD rider. 2. A power application device (PAD) that interfaces with a PAD rider and an external, foot-operated wheeled vehicle, wherein said PAD comprises: a) a main frame or attachment tube having a front end, a rear end, an upper surface and a lower surface,b) a handle bar having a right hand grip, a left hand grip and a center mounting post that is rotatably attached to a vertical post sleeve located on the front end of said attachment tube,c) a front body support that is adjustably attached to the upper surface of said attachment tube rearward from said handle bar,d) a body pull tether attached to the rear surface of said front body support, wherein the tether is attached to a hook located on a harness or belt worn by the PAD rider,e) an optional rear body support that is adjustably attached to the upper surface of said attachment tube rearward from said front body support,f) a drive-wheel powering means comprised of an electrical power circuit comprising: (1) a battery having a positive (+) terminal and a negative (−) terminal,(2) an electric d-c motor having an electrical input, an electrical output and an output shaft that is attached directly to said drive wheel, or by a chain drive or a belt drive,(3) a variable resistor connected between the (+) terminal of said battery and the electrical input of said electric d-c motor,(4) a power switch connected between the electrical output of said electrical motor and the (−) terminal of said battery, wherein when said power switch is placed in an ON position, the electrical power circuit is activated, thereby allowing said variable resistor to control the speed of said electric d-c motor which in turn, controls the rotational speed of the drive wheel,g) a mounting structure having means for being attached to the rear end of said attachment tube, wherein said mounting structure having means for securing said battery and said electric d-c motor with the attached drive wheel, wherein said variable resistor is an integral element of either the right or the left hand grip, wherein the electrical wiring from said electrical power circuit is routed through said attachment tube and attached to said variable resistor, andh) a disk brake that is attached to one side of said drive wheel, wherein said disk brake is operated by a brake cable or hydraulic line that is operated by a hand-controlled lever that is attached to one side of said handle bar. 3. The PAD as specified in claim 2 wherein said mounting structure attachment means comprises a solid rod that is rigidly attached to and that extends forward from said mounting structure, wherein the rod is dimensioned to be frictionally inserted into the rear end of said attachment tube and secured thereto by a tethered locking pin. 4. The PAD as specified in claim 2 wherein said attachment tube has: a) a circular cross-section, a rectangular cross-section or a laminated cross-section,b) a front end that is elevated from the rear end of said attachment tube to compensate for the height of the PAD rider, andc) a right or a left body curve that extends horizontally around the side of the PAD rider. 5. The PAD as specified in claim 2 wherein said front and rear body supports are padded and contoured to interface respectively with the abdomen and the lower back area of the PAD rider. 6. The PAD as specified in claim 5 wherein the front body support has a rear surface to which is attached the body pull tether, wherein the tether is releasably attached to an open hook located on a belt or harness that is attached around the abdominal area of a PAD rider. 7. The PAD as specified in claim 2 wherein said battery is comprised of a rechargeable battery. 8. The PAD as specified in claim 2 wherein said electric d-c motor is comprised of a variable-speed d-c motor having a shaft that is attached directly to said drive wheel or by means of a chain or belt drive. 9. The PAD as specified in claim 2 wherein said variable resistor is comprised of a rheostat. 10. The PAD as specified in claim 2 wherein said mounting structure is designed to provide an even distribution of weight when said electrical d-c motor and said battery are secured. 11. The PAD as specified in claim 2 further comprising a trailing-wheel that is attached by an attachment means to the rear end of said attachment tube, wherein said trailing wheel stabilizes said PAD.
