What is claimed is: 1. A bicycle engagement device adapted for use with a pedaled device, the device comprising: a tube; a rod slidable with respect to the tube; a wheel engagement member coupled to the rod; a driving mechanism movable between a first position and a second position along a length of an outer surface of the tube, the driving mechanism including a lever pivotable about a pivot pin with respect to the tube and a driving pin coupled to the lever and adapted to engage the rod to provide movement of the rod relative to the tube, wherein the driving pin is positioned within a slot of the rod, the lever adapted to move the driving pin in an arcuate path; and a locking mechanism adapted to lock the rod relative to the tube. 2. The device of claim 1 wherein the tube includes a pair of nylon bushings to frictionally engage the rod. 3. The device of claim 1 wherein the lever is positioned around a portion of the outer circumference of the tube. 4. The device of claim 1 wherein the locking mechanism includes a locking portion positioned in the slot that is offset with respect to a central axis of the rod. 5. The device of claim 4 wherein the locking portion further comprises a pocket that is offset with respect to a longitudinal portion of the slot. 6. The device of claim 1 wherein the tube includes an arcuate slot to accommodate the driving pin. 7. The device of claim 1 wherein the rod includes a recess to accommodate the pivot pin. 8. The device of claim 1 and further comprising: a frame coupled to the tube; a support end coupled to the frame and spaced apart from the tube; and a second wheel engagement member movably coupled to the support end. 9. A method of securing a wheel of a bicycle to an exercise device, comprising: providing a frame with first and second support ends; providing a first wheel engagement member coupled to the first support end; providing a second wheel engagement member coupled to the second support end; providing a rod coupled to the first wheel engagement member; providing a driving mechanism movable between a first position and a second position along an outer surface of a length of the first support end to drive the rod relative to the first support end, the driving mechanism including a lever pivotable about a pivot pin with respect to the first support end and a driving pin coupled to the lever and adapted to engage the rod, wherein providing the driving mechanism further comprises providing a slot in the rod and positioning the driving pin in the slot; and providing a locking mechanism to lock the rod relative to the first support end, which comprises providing a locking portion in the slot, the locking portion being offset with respect to a longitudinal portion of the slot and a central axis of the rod. 10. The method of claim 9 and further comprising: positioning a bicycle wheel between the first wheel engagement member and the second wheel engagement member; and actuating the lever to lock the bicycle wheel with respect to the frame. 11. The method of claim 9 and further comprising: providing a recess in the rod to accommodate the pivot pin. 12. The method of claim 9 and further comprising: providing an arcuate slot in the first support end to accommodate the driving pin. 13. A bicycle trainer for supporting a pedaled device, comprising: a frame; a first support end coupled to the frame; a second support end spaced apart from the first support end and coupled to the frame; a first wheel engagement member coupled to the first support end; a second wheel engagement member coupled to the second support end; a rod coupled to the first wheel engagement member and slidable with respect to the first support end; a pivot pin coupled to the first support end; a driving pin pivotable about the pivot pin between a first position and a second position, the driving pin forming a pin-slot connection with the rod in order to drive the rod with respect to the first support end; and a slot engaging the driving pin such that the rod is movable with respect to the first support end when the driving pin is in the first position and locked with respect to the first support end when the driving pin is in the second position. 14. The trainer of claim 13, wherein the driving pin and the pivot pin are coupled to a lever. 15. The trainer of claim 13, wherein the slot is positioned within the rod. 16. The trainer of claim 13, wherein the slot includes a pocket positioned therein to receive the driving pin in the second position. 17. The trainer of claim 13 wherein the driving pin travels in an arcuate path. 18. A bicycle trainer for supporting a pedaled device, comprising: a frame; a first support end coupled to the frame, the first support end comprising: a tube; a rod slidable with respect to the tube; a wheel engagement member coupled to the rod; a driving mechanism movable between a first position and a second position along a length of an outer surface of the tube, the driving mechanism including a lever pivotable about a pivot pin with respect to the tube and a driving pin coupled to the lever and adapted to engage the rod to provide movement of the rod relative to the tube, wherein the rod includes a recess to accommodate the pivot pin; and a locking mechanism adapted to lock the rod relative to the tube; and a second support end spaced apart from the first support end and coupled to the frame. 19. The bicycle trainer of claim 18 wherein the lever is positioned around a portion of the outer circumference of the tube. 20. The bicycle trainer of claim 18 wherein the locking mechanism includes a locking portion positioned in the slot that is offset with respect to a central axis of the rod. 21. The bicycle trainer of claim 20 wherein the locking portion further comprises a pocket that is offset with respect to a longitudinal portion of the slot. 22. The bicycle trainer of claim 1 wherein the tube includes an arcuate slot to accommodate the driving pin.
