Alternatively, when the adjustingbar 22 of therear frame 20 is driven by operation of theadjusting mechanism 40 and is moved toward thesupport pipe 12 of themain frame 10 from the position as shown inFIG. 7 to the position as shown inFIGS. 1 and 3 , the connectinglever 25 of therear frame 20 is pushed upward so that thefirst linkage 15 of themain frame 10 is pushed upward. In such a manner, thefirst linkage 15 of themain frame 10 is moved upward and forward, and thesecond linkage 17 of themain frame 10 is moved forward by action of thethird linkage 18. Thus, theseat 16 of themain frame 10 is moved upward and forward, and thehandlebar 171 of themain frame 10 is moved forward as shown inFIGS. 1 and 3 , so that a user can operate the exercising bike in a sitting posture. - Accordingly, the position of the
seat 16 of themain frame 10 can be adjusted so that a user can operate the exercising bike in a sitting or lying posture, thereby enhancing the exercising effect. In addition, theroller 24 of therear frame 20 is moved in thesupport pipe 12 of themain frame 10 so that the adjustingbar 22 of therear frame 20 is moved in thesupport pipe 12 of themain frame 10 smoothly by guidance of theroller 24 and will not produce noise during movement. Further, thedriving mechanism 30 and theadjusting mechanism 40 are selected individually to decrease the cost of fabrication. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
