A single leg support for sitting on by a user has a seat member adjustably connected to a post member, with the post member connected to a base member which contacts a ground surface. In typical use, the support axis of the support is between about five and twenty-five degrees relative to the vertical such that the user remains in equilibrium with most of his/her weight supported by his two legs at about five degrees from the vertical with the knees slightly bent. Thus, the support carries only a small portion of the user's weight for increased comfort. The support is adapted to be fitted into a bicycle. Additionally, the support may be used with a heavy base member having a flexible joint allowing rotating movement of the support while a user is seated thereon.

I claim: 1. A single-leg support for supporting a user in a generally standing position on a ground surface, said single-leg support comprising: a seat member comprising a seat post and a saddle upon which the user rests for support in said standing position; a post member for releasably and axially adjustably receiving the seat post of the seat member; a base member comprising a base post and a base cap connected thereto and adapted for resting of the base cap on the ground surface with the base post supporting said post member, and thereby said seat member and said user, thereabove when said user is supported on said seat member in said standing position; and an attachment mechanism comprising a resilient metal band attached to the post member and adapted for axial insertion of the base post thereinto, said resilient metal band having a first through hole for releasable engagement therein of a first locking pin on said base post for releasably attaching said base member to said post member. 2. The support of claim 1, wherein said base member comprises an anchor pin base insertable into the ground surface when said base member rests thereupon. 3. The support of claim 1, wherein said seat member is telescopically adjustably connected to said post member for telescopic adjustment of said seat member along a first axis defined by said seat post and said post member for adjusting a height of said seat member to support said user in said standing position. 4. The support of claim 3, wherein said seat post is adapted for sliding connection within said post member for telescopic sliding relative thereto to provide said telescopic adjustment, said seat post being releasably retained in place relative said post member by a releasable clamp disposed on said post member. 5. The support of claim 3, wherein said post member comprises a gas piston cylinder containing a gas in which said seat post is housed, said seat post forming a piston shaft for said gas piston cylinder, said height of said seat member being telescopically adjustable by increasing an amount of gas in said cylinder to increase said height and by decreasing said amount to decrease said height. 6. The support of claim 1, wherein said support is adapted for insertion into a bag for carriage of said support therein. 7. The support of claim 6, wherein said seat member and said post member are adapted for insertion into said bag by detaching said seat member from said post member and inserting said seat member and said post member into said bag. 8. The support of claim 1, wherein said seat member comprises a handle for carrying said support. 9. The support of claim 1, wherein said base member comprises a base cap releasably attached to said post member, said base cap being adapted for resting on the ground surface and made of a sliding free material for allowing detachment of said base member from said post member. 10. The support of claim 1, wherein said base member comprises a removable suction cup base for providing suction between said base member and the ground surface when said base member rests thereupon. 11. The support of claim 1, wherein said base member, said post member, and said seat member are substantially equal in length. 12. The support of claim 1, wherein said support is adapted for inserting of said base member and said post member through a sleeve of a bicycle frame with said base member engaged locked in a base receptacle of said bicycle frame in register with said sleeve for providing a seat for said bicycle, said base member being releasably lockable in place in said base receptacle by a locking means for said base receptacle and said post member being releasably attached to said sleeve with a clamp situated on said sleeve. 13. The support of claim 1, said support is adapted for axial inserting of said post member and said base member into a seat tube of a bicycle frame and for releasable attachment therein with a clamp situated on said seat tube and with said seat member extending out of said seat tube and thereby providing a seat for said bicycle. 14. The support of claim 1, wherein said resilient metal band has open extremities adapted for axial insertion of said post member and said base post therein and a second through hole for engagement of a second locking pin for said post member therein, said resilient metal band being thereby releasably attachable to both said post member and said base member. 15. A single-leg support for supporting a user in a generally standing position on a ground surface, said single-leg support comprising: a seat member upon which the user rests for support in said standing position; a post member for releasably and axially adjustably receiving the seat member; and a base member releasably attached to said post member, said base member being adapted for resting on the ground surface and supporting said post member, and thereby said seat member and said user, thereabove when said user is supported on said seat member in said standing position, said base member comprising a base plate, releasably attachable to said ground surface, and a tiltable flexible joint mounted on said base plate and to which said post member is releasably attached, said flexible joint being disposed between said base plate and said post member and providing tilting and rotatable movement of said post member relative said base plate. 16. The support of claim 15, wherein said flexible joint is adapted to resiliently bias said post member, and thereby said support, into an upright configuration in which said post member is disposed substantially perpendicular relative to said base plate. 17. The support of claim 16, wherein said joint comprises a resilient solid rubber block disposed between said base plate and said post member. 18. The support of claim 16, wherein said joint comprises a resilient pneumatic rubber balloon and a balloon housing in which said rubber balloon is housed, said balloon and said rubber housing being disposed between said base plate and said post member. 19. The support of claim 16, wherein said base plate comprises a plate collar and said flexible joint comprises a flange extending therearound, said plate collar being attached to said base plate with screws and extending around and over said flange in mating abutment therewith for retaining said flange, and thereby said joint, in abutting contact with said base plate to attach said joint to said base plate. 20. The support of claim 19, wherein said joint has connector protrusions, situated generally opposite said flange, extending therefrom and adapted for secure and retaining insertion into a top portion of said joint to which said post member is attached. 21. The support of claim 16, wherein said base member further comprises an abutment member adjustably mounted on said base plate in proximity to a top portion of said joint to which said post member is attached, said abutment member being adapted to abut said top portion when said support is in said upright configuration to prevent backward tilting of said post member beyond said upright configuration. 22. The support of claim 21, wherein said abutment member is mounted on said base plate by a connector member attached to said base plate and extending upwardly therefrom, said abutment member being mounted in said connector member in proximity to said top portion. 23. The support of claim 22 wherein said abutment member is mounted in said connector member with an adjustable blot screw, said abutment member being adjustable relative said top portion by turning of said blot screw to adjust said upright configuration. 24. The support of claim 16, wherein said base member further comprises a circular safety collar mounted on said base plate and extending around said post member, said safety collar limiting tilting and rotation of said post member relative said base plate to an inner perimeter of said safety collar.
