BACKGROUND OF THE INVENTION [0001] 1. Fields of the Invention [0002] The invention relates to an recumbent cycle with an adjustable seat, and more particularly, to an recumbent cycle with an adjustable seat to meet the needs or requirements of an operator as well as a position-adjusting mechanism for moving the seat of the recumbent cycle in desired position. [0003] 2. Description of the Related Art [0004] The busy modern people set more and more emphasis on the physical health and go to the training centers to do some physical exercises in the spare time. But the most criticized defect of all kinds of sports equipments is their fixed sizes and dimensions, which can not fit people with different height and figure. [0005] From the description of the TW 84201826--"adjustable structure of recumbent cycle seats", we can acquire that the change of seats position in sports equipment in beginning phase will be fulfilled with the double columns which have some drilling holes. But the screw must be demounted, the column has to be extended or retracted for increasing or decreasing the total length thereof, and then the screw has to be fastened. The procedure is too complicated and hard to carry out. [0006] In order to eliminate the above-mentioned disadvantage, a base is installed under the seat. A control lever is employed to manipulate an eccentric resistant block to achieve a function of clamping positioning and rotating release. Although the position of the seat can be set in the equipment chassis, a rubber cushion is placed between the seat and the chassis for the damping purpose. The wear on contacting area is significant and it resists the movement of seat. Then, the resistant block is not easy to press the chassis and fix the seat in position. [0007] Furthermore, a sliding groove which is set in one side of chassis is disclosed in the TW 92208115--"The Structure of Adjustable Recumbent Cycle". The adjusting welding parts is mounted at a bottom end of the groove. The seat connects with these welding parts and can extend and retract any time in storage position within this sliding groove. This structure is very similar to the prior art, and the whole structure is complicated and it brings difficulty for the maintenance. SUMMARY OF THE INVENTION [0008] It is a primary object of the invention is to provide a recumbent cycle that features a simple configuration and allows for an easy adjustment of the seat position. [0009] It is another object of the invention is to provide a position-adjusting mechanism that is suitable for all kinds of exercise apparatuses including recumbent cycle. [0010] In order to achieve the above-mentioned object, a recumbent cycle including a primary frame consisting of a base frame and an upright frame. The frame unit has a secondary frame including a first end with a drive wheel. Two cranks each with one pedal are rotatably supported on a shaft of the drive wheel to impart motion to a flywheel. A guide wheel is rotatably mounted on a second end of the secondary frame for securing a position-adjusting mechanism to the secondary frame such that a tube is movable on the guide wheel and adapted to extend from a main body and retract thereinto. BRIEF DESCRIPTION OF THE DRAWINGS [0011] The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which: [0012] FIG. 1 is a perspective view of a recumbent cycle with an adjustable seat; [0013] FIG. 2 is a partial sectional view of a position-adjusting mechanism; [0014] FIG. 3 is a perspective view of a tube in accordance with FIG. 2 in partial section; and [0015] FIG. 4 is a perspective view of a main body in accordance with FIG. 2 in partial section. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0016] Referring to FIG. 1, a recumbent cycle 100 includes a primary frame 10 with a base frame 11 and an upright frame extending from one end of the base frame 11. The primary frame 10 further includes a drive wheel 13 with two cranks 14 supported on a shaft. Each of the cranks 14 has a pedal 15 at a free end thereof. The pedals 15 moves in an alternating succession to impart rotary motion to the drive wheel 13. Meanwhile, the rotary motion is imparted to a flywheel 17 by a belt 16. A resistance apparatus (not shown) is attached to the flywheel 17 such that the loading of the operator or the resistance during an exercise session is increased. [0017] Besides, the primary frame 10 includes a secondary frame 20. The drive wheel 13 is supported at one end of the secondary frame 20 while a guide wheel 21 is pivotally positioned at the other end thereof. A position-adjusting mechanism 30 includes a main body 31 fixed on the secondary frame 20 in place. A tube 32 extendable and retractable within the main body 31 is slidably disposed on the guide wheel 21. A control lever 33 is adapted to adjust the position of the tube 32. In this way, a seat 22 on the tube 32 is displaceable relative to the main body 31 responsive to user manipulation of the control lever 33 extending from the tube 32. Accordingly, the effect to adjust the seat position on the recumbent cycle 100 can be achieved. [0018] The recumbent cycle 100 assembled by the aforementioned components can be additionally equipped with an electronic console 18 for indicating all kinds of exercise values and actuating different actions of function keys. Furthermore, the operator can adjust the position of the seat according to individual needs or requirements. In addition, the operator can adjust the position of the seat on the recumbent cycle 100 only by moving the control lever 33. It's more convenient than the conventional recumbent cycle in which the position of the seat is adjustable by screwing action. Meanwhile, the recumbent cycle 100 in accordance with the invention has a more simple construction and is more easily operable. [0019] FIG. 2 illustrates a position-adjusting mechanism 30 for the recumbent cycle 100. The position-adjusting mechanism 30 includes a hollow-shaped main body 31. A stop pad 311 is positioned at one end of the main body 31 while the tube 32 is movably received within the main body 31. The inside of the main body 31 serves as a hollow 312, and the tube 32 includes a roller 321 installed at one end of the hollow 312. The roller 321 is so dimensioned that it precisely fits into the hollow 312 and is in contact with top and bottom walls 3121 of the hollow 312. In this way, the tube 32 is more smoothly displaceable relative to the main body 31 with an economy of effort. [0020] The tube 32 includes a limit piece 322 at one end thereof within the hollow 312. The limit piece 322 has two opposing support members 323. The roller 321 is pivotally coupled in close vicinity to the end portion between the support members 323. Two blocking elements 324 are interposed between the roller 321 und the limit piece 322. The limiting elements 324 each include a contact pad 3241 facing the walls 3121 so that the tube 32 can be fixed at any shiftable position within the hollow 312 of the main body 31.
