Some exercise devices such as bicycles can be moved but they have a fixed operation mode which is circular operation by feet. The two types of exercises are existed in separate in the market. [0003] The present invention intends to provide an exercise device which includes a driving mechanism that is able to be cooperated with different types of operation modes and drives the exercise device forward. SUMMARY OF THE INVENTION [0004] The present invention relates to an exercise device which comprises a frame with a front wheel and two rear wheels which are connected to a shaft. A driving mechanism includes a uni-direction gear mounted to the shaft and an acceleration gear which is engaged with the uni-direction gear. A rack has an end connected to an operation device and the other end of the rack is engaged with the acceleration gear. The driving mechanism drives the front wheel or the rear wheels. [0005] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0006] FIG. 1 is a side view to show the exercise device used as a climbing device; [0007] FIG. 2 is a bottom view of the climbing device in FIG. 1; [0008] FIG. 3 is a side view to show the exercise device used as a treadmill; [0009] FIG. 4 is a bottom view of the treadmill in FIG. 1; [0010] FIG. 5 is a side view to show the exercise device used as a twist machine; [0011] FIG. 6 is a side view of the twist machine in FIG. 5; [0012] FIG. 7 is a bottom view of the twist machine in FIG. 5; [0013] FIG. 8 is a bottom view of another embodiment of the exercise device used as a treadmill; [0014] FIG. 9 shows a side view of the treadmill in FIG. 8; [0015] FIG. 10 is a side view of another embodiment of the exercise device used as a climbing machine; [0016] FIG. 11 is a bottom view of the climbing machine in FIG. 10, and [0017] FIG. 12 shows yet another embodiment of the exercise device used as a climbing machine. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0018] Referring to FIGS. 1 and 2, the exercise device 10 of the present invention comprises a frame 15 with a front wheel 13 and two rear wheels 14 which are connected to two ends of a shaft 21, and a post 11 extends from a top of the frame 15 and a handle 12 is connected to the post 11. [0019] A driving mechanism 20 for driving each of the rear wheels 14 includes a uni-direction gear 212 which is mounted to the shaft 21 and an acceleration gear 22 is engaged with the uni-direction gear 212. The acceleration gear 22 is connected with a uni-direction bearing 214. A rack 23 has an end connected to an operation device 16 and the other end of the rack 23 is engaged with the acceleration gear 22, so that when operating the operation device 16 to move the rack 23, each of the rear wheels 14 is driven to let the exercise device 10 move forward. The driving mechanism 20 may also be used to drive the front wheels 13. It is noted that the number of the front wheels 13 can be two. A bearing 211 or a uni-direction bearing 214 is connected between the frame 15 and the shaft 21. Continue reading about Dual-function exercise device...
