Patent Claims:	1. A device comprising a first substantially upright support member; a second substantially upright support member; and a substantially rigid transverse member joining said first support member to said second support member; said first upright support member being connected to hand engaging means approximate its upper end, and connected at its lower end to means slidable with respect to said first upright support member, said slidable means being linked to means for biasing said slidable means downwardly, said slidable means having ground-engaging means at its bottom end, said second upright support member being connected to seating means at its upper end, and at its lower end, connected to means slidable with respect to said second upright support member, said second upright support member being linked to means for biasing said second slidable means downwardly, said second slidable means having at its bottom end ground-engaging means. 2. The device of claim 1 wherein said slidable means comprise leg means that fit within, and are slidable with respect to said upright support members, and said biasing means lie inside said upright support means above said slidable leg means and below means for preventing displacement of said biasing means when said biasing means exert maximum upward force thereon. 3. The device of claim 2 wherein each of said slidable leg means comprises shoulder means near the upper end of said leg means that engage said biasing means, and, removably attached to the bottom of said first and second upright support members, means for preventing said shoulder means from escaping said upright support means. 4. The device of claim 1 wherein said hand engaging means further comprising handlebar means connected to said first upright support member at its upper end. 5. A device comprising a first substantially upright support member; a second substantially upright support member; and a substantially rigid transverse member joining said first support member to said second support member; said first upright support member being connected to handlebar means at its upper end, and connected at its lower end to means slidable with respect to said first upright support member, said slidable means being linked to means for biasing said slidable means downwardly, said slidable means having a substantially flat, ground-engaging surface at its bottom end, said second upright support member being connected to seating means at its upper end, and, at its lower end, connected to means slidable with respect to said second upright support member, said second upright support member being linked to means for biasing said second slidable means downwardly, said second slidable means having at its bottom end a substantially flat, ground-engaging surface and, connected to said rigid transverse member along a common axis near, and in front of said second upright support member, two foot pegs, one extending laterally from one side of said rigid transverse member, the other extending laterally from the other side of said rigid transverse member. 6. The device of claim 5 wherein said first upright support member, said second upright support member and said rigid transverse member comprise a frame whose length and height approximates the length and height of a trail motorcycle. 7. The device of claim 5 wherein said handlebars have a length and a height above the ground-engaging surfaces that approximate those of a trail motorcycle. 8. The device of claim 5 wherein said slidable means comprise leg means that fit within, and are slidable with respect to said upright support members, and said biasing means lie inside said upright support means above said slidable leg means and below means for preventing displacement of said biasing means when said biasing means exerts maximum upward force thereon. 9. The device of claim 5 wherein said flat, ground-engaging surfaces comprise flat-bottomed pads connected to each of said slidable means through ball-and-socket joints that are adapted to permit lateral movement of said device. 10. A device comprising a first substantially upright support member; a second substantially upright support member; and a substantially rigid transverse member joining said first support member to said second support member; said first upright support member being connected to handlebar means at its upper end, and connected at its lower end to means slidable with respect to said first upright support member, said slidable means being linked to means for biasing said slidable means downwardly, said slidable means having ground-engaging means at its bottom end, said second upright support member being connected to seating means at its upper end, and, at its lower end, connected to means slidable with respect to said second upright support member, said second upright support member being linked to means for biasing said second slidable means downwardly, said second slidable means having at its bottom end ground-engaging means and, connected to said rigid transverse member along a common axis near, and in front of said second upright support member, two foot pegs, one extending laterally from one side of said rigid transverse member, the other extending laterally from the other side of said rigid transverse member. 11. The device of claim 10 wherein said first upright support member, said second upright support member and said rigid transverse member comprise a frame whose length and height approximates the length and height of a trail motorcycle. 12. The device of claim 10 wherein said handlebars have a length and a height above the ground-engaging means that approximate those of a trail motorcycle. 13. The device of claim 10 wherein said slidable means comprise leg means that fit within, and are slidable with respect to said upright support members, and said biasing means lie inside said upright support means above said slidable leg means and below means for preventing displacement of said biasing means when said biasing means exerts maximum upward force thereon. 14. The device of claim 10 wherein said ground-engaging means comprise rotatable wheel means.
