What is claimed is: 1. A skateboard comprising:a main board having a top surface, a bottom surface, a front end, and a rear end, the main board having a flat middle area between the front end and the rear end;a front bracket attached to the bottom surface of the main board near the front end of the main board;a front axle attached to the front bracket;a front pair of wheels rotatable about the front axle and comprising a first wheel and a second wheel, the first wheel and the second wheel of the front pair of wheels being attached to the front bracket;a rear bracket attached to the bottom surface of the main board near the rear end of the main board;a rear axle attached to the rear bracket;a rear pair of wheels rotatable about the rear axle and comprising a first wheel and a second wheel, the first wheel and the second wheel of the rear pair of wheels being attached to the rear bracket;a front track located on the middle of the bottom surface of the main board in the front half of the main board, the front track having a front set of teeth;a rear track located on the bottom surface of the main board in the rear half of the main board, the rear track having a rear set of teeth;a lower support bar having a front end, a rear end, a top surface, and a bottom surface, the front end of the lower support bar being attached to the front bracket, the rear end of the lower support bar being attached to the rear bracket;a stopper block attached to the top surface of the lower support bar;a central bracket located on the bottom surface of the main board;a pair of V-frames comprising a front V-frame and a rear V-frame, each V-frame having a first end and a second end, the first end of each V-frame being connected to the central bracket, the second end of the front V-frame being connected to the front set of teeth, the second end of the rear V-frame being connected to the rear set of teeth;a first roller wheel attached to the front V-frame halfway in between the first end and the second end of the front V-frame;a second roller wheel attached to the rear V-frame halfway in between the first end and the second end of the rear V-frame;a first spring attached between the first end and the second end of the front V-frame;a second spring attached between the first end and the second end of the rear V-frame;a front-toothed gear axially mounted on the front axle, the front toothed gear located adjacent to one of the wheels of the front pair of wheels;a front lower support gear connected to the front-toothed gear;a front upper support gear connected to the front lower support gear, the front upper support gear also connected to the front set of teeth;a rear-toothed gear axially mounted on the rear axle, the rear-toothed gear located adjacent to one of the wheels of the rear pair of wheels; anda rear upper toothed gear attached to the rear-toothed gear, the rear upper toothed gear also connected to the rear set of teeth;wherein each of the gears rotatable in a first direction and a second direction, the first direction and the second direction being opposite directions;wherein placing downward pressure on the center of main board reduces the distance between the, main board and support bar causing the V-frames to expand;wherein the V-frames force the front set of teeth outward toward the front end of the main board and the rear set of teeth outward toward the rear end of the main board, further the front set of teeth rotate the front upper support gear in the first direction which rotates the front lower support gear in the second direction which rotates the front-toothed gear in the first direction; andwherein the rear set of teeth rotates the rear upper toothed gear in the second direction which rotates the rear-toothed gear in the first direction, thereby propelling the skateboard in a forward manner.
