An exercise apparatus includes a base providing a relatively higher first terminal end, a relatively lower second terminal end, and a track between the first and second terminal ends. The exercise apparatus also includes a seat unit movable along the track between a first position adjacent to the first terminal end and a second position located far apart from the first terminal end. A distance difference relative to the seat unit is produced by a wheel pedal unit movable along the track between a first pedaling position adjacent to the second terminal end and located horizontally far apart from the seat unit, and a second pedaling position located far from the second terminal end and horizontally adjacent to the seat unit. Thus, changing the position of the wheel pedal unit and the position of the seat unit can change the distance difference between the seat unit and the wheel pedal unit in both the vertical and horizontal directions. This enables a user to selectively perform different exercise modes in either a normal sitting posture or a recumbent sitting posture.

1. An exercise apparatus, comprising: a base comprising a first terminal end and a second terminal end located at different elevations and spaced from each other at a predetermined distance, and a track extending between said first and second terminal ends;a seat unit mounted at said track of said base and movable relative to said base between a first position adjacent to said first terminal end and a second position spaced far apart from said first terminal end; anda wheel pedal unit mounted at said track of said base and movable relative to said base between a first pedaling position adjacent to said second terminal end and horizontally spaced far apart from said seat unit, and a second pedaling position spaced far apart from said second terminal end and located horizontally adjacent to said seat unit to produce a distance difference between said wheel pedal unit and said seat unit in a horizontal direction and a distance difference between said wheel pedal unit and said seat unit in each of said first and second positions in a vertical direction. 2. The exercise apparatus as claimed in claim 1, wherein said track is smoothly arched and inwardly curved, and said first and second terminal ends are respectively located at two opposite ends of said track. 3. The exercise apparatus as claimed in claim 2, wherein said base comprises at least one frame bar member having a body for positively positioning on a support surface, and forming said first and second terminal ends, wherein said track is located above said body and between said first and second terminal ends. 4. The exercise apparatus as claimed in claim 3, wherein said wheel pedal unit comprises at least one through hole configured to correspond with a curvature of said at least one frame bar member for the insertion of said at least one frame bar member therein. 5. The exercise apparatus as claimed in claim 4, further comprising at least one locking member. 6. The exercise apparatus as claimed in claim 5, wherein said at least one locking member is insertable into said at least one respective through hole to lock said wheel pedal unit to said track of said at least one frame bar member. 7. The exercise apparatus as claimed in claim 2, wherein said seat unit comprises a seat cushion, a back cushion, and a coupling member located at said back cushion and coupled to said track. 8. The exercise apparatus as claimed in claim 2, further comprising a handle assembly pivotally connected to said wheel pedal unit and movable relative to said wheel pedal unit between a first position in substantial alignment with said track and a second position extending away from said track. 9. The exercise apparatus as claimed in claim 8, wherein said handle assembly comprises a coupling end piece located at one end thereof and pivotally connected to said wheel pedal unit, a handlebar located at an opposite end thereof for holding by a user, and an arched stem connected between said coupling end piece and said handlebar. 10. The exercise apparatus as claimed in claim 9, wherein the arched stem is curved subject to the curvature of said track. 11. The exercise apparatus as claimed in claim 9, wherein said arched stem is configured such that said handlebar is kept spaced far apart from said seat unit when said handle assembly is in said second position. 12. The exercise apparatus as claimed in claim 9, wherein said arched stem is arranged to lie substantially flush with said track when said handle assembly is in said second position. 13. The exercise apparatus as claimed in claim 9, wherein said handlebar comprises two grips respectively located at two distal ends thereof, said grips being located at two opposite lateral sides relative to said seat unit when said handle assembly is in said first position. 14. The exercise apparatus as claimed in claim 1, wherein when said seat unit is in said first position and said wheel pedal unit is in said second pedaling position, the distance difference between said seat unit and said wheel pedal unit is maximized in the vertical direction and minimized in the horizontal direction, and when said seat unit is in said second position and said wheel pedal unit is in said first pedaling position, the distance difference between said seat unit and said wheel pedal unit is minimized in the vertical direction and maximized in the horizontal direction. 15. An exercise apparatus, comprising: a base having at least two frame bar members arranged parallel to each other and defining a body for steadily positioning on a support surface;an arched track spaced above the body, said track defining a first terminal end and an opposite second terminal end spaced from each other at a predetermined distance;a seat unit movably mounted to the track of said base and movable relative to said base between a first position adjacent to said first terminal end and a second position spaced far apart from said first terminal end; anda wheel pedal unit movably mounted at the track of said base and movable relative to said base between a first pedaling position adjacent to said second terminal end and horizontally spaced far apart from said seat unit, and a second pedaling position spaced far apart from said second terminal end and located horizontally adjacent to said seat unit to produce a distance difference between said wheel pedal unit and said seat unit in a horizontal direction, and a distance difference between said wheel pedal unit and said seat unit in each of said first and second positions in a vertical direction. 16. The exercise apparatus as claimed in claim 15, wherein said first and second terminal ends are located at different elevations. 17. The exercise apparatus as claimed in claim 15, wherein the base further comprises two retaining members fastened to the at least two frame bar members for providing support. 18. An exercise apparatus, comprising: a base having at least two curved frame bar members arranged parallel to each other and defining an arched track spaced above a body, said track defining a first terminal end and an opposite second terminal end spaced from each other at a predetermined distance;a seat unit movably mounted to the track of said base and movable relative to said base between a first position adjacent to said first terminal end and a second position spaced far apart from said first terminal end;a wheel pedal unit slidably mounted at the track of said base and movable relative to said base between a first pedaling position adjacent to said second terminal end and horizontally spaced far apart from said seat unit, and a second pedaling position spaced far apart from said second terminal end and located horizontally adjacent to said seat unit to produce a distance difference between said wheel pedal unit and said seat unit in a horizontal direction, and a distance difference between said wheel pedal unit and said seat unit in each of said first and second positions in a vertical direction; andwherein said wheel pedal unit comprises at least one through hole configured to correspondingly fit with the curvature of said at least one frame bar member for the insertion of said at least one frame bar member therein. 19. The exercise apparatus as claimed in claim 18, further comprising a handle assembly pivotally connected to said wheel pedal unit and pivotable relative to said wheel pedal unit between a first position in substantial alignment with said track and a second position extending away from said track. 20.
