With reference to FIGS. 3 and 4, the pedal set 30 has a supporting stand 31, an axle 311, a first supporting rod 32, a second supporting rod 33, a first pedal 34, a second pedal 35, and multiple elastic rings 36. The support stand 31 is fixed on the top side of the rear bar 112 of the base 11. The axle 311 is assembled on the supporting stand 31, and has two ends. The first supporting rod 32 is connected to the bottom side of the base 11 below one of the two ends of the axle 311, and the second supporting rod 33 is connected to the bottom side of the base 11 below the other one of the two ends of the axle 311. The first supporting rod 32 has two first hitching bars 321, and each one of the first hitching bars 321 is disposed on a respective one of a front side and a rear side of the first supporting rod 32. The second supporting rod 33 has two second hitching bars 331, and each one of the second hitching bars 331 is disposed on a respective one of a front side and a rear side of the second supporting rod 33. With reference to FIG. 3, in the preferred embodiment, the two first hitching bars 321 and the two second hitching bars 331 are L-shaped bars.

The first pedal 34 has a first pedal rod 341 mounted on a bottom side of the first pedal 34. The first pedal rod 341 has an axle socket 343 and two first connecting bars 342. The axle socket 343 of the first pedal rod 341 is located between the two first connecting bars 342, and is pivotally mounted with one of the two ends of the axle 311. The second pedal 35 has a second pedal rod 351 mounted on a bottom side of the second pedal 35. The second pedal rod 351 has an axle socket 353 and two second connecting bars 352. The axle socket 353 of the second pedal rod 351 is located between the two second connecting bars 352, and is pivotally mounted with the other one of the two ends of the axle 311.

Two of the multiple elastic rings 36 are connected between the first supporting rod 32 and the first pedal rod 341, and each one of said two elastic rings 36 is sheathed on a respective one of the two first connecting bars 342 and a respective one of the two first hitching bars 321. Another two of the multiple elastic rings 36 are connected between the second supporting rod 33 and the second pedal rod 351, and each one of said another two elastic rings 36 is sheathed on a respective one of the two second connecting bars 352 and a respective one of the two second hitching bars 331. In the preferred embodiment of the present invention, there are four said above-mentioned elastic rings 36. However, the amount of the multiple elastic rings 36 may be easily adjusted upon practical demands. With aforementioned technical features, when the first pedal 34 and the second pedal 35 swing, resilient forces would be provided by the multiple elastic rings 36.

One of the two angle sensors 40 is mounted on the second pedal rod 351 of the second pedal 35, at a spaced interval from the axle socket 353 of the second pedal 35 and the axle 311. Once the second pedal 35 swings about the axle 311, the angle sensor 40 mounted with the second pedal 35 may detect an angle for which the second pedal 35 has rotated. The other one of the two angle sensors 40 is mounted on the first pedal rod 341 of the first pedal 34, at a spaced interval from the axle socket 343 of the first pedal 34 and the axle 311. Once the first pedal 34 swings about the axle 311, the angle sensor 40 mounted with the first pedal 34 may detect an angle for which the first pedal 34 has rotated. Furthermore, each one of the two angle sensors 40 is connected with the display 13 via wireless transmission or a signal line so as to transmit information about the sensed angles to the display 13, and the display 13 shows the information to the user. The working principles of the angle sensors 40 are conventional, and description thereof is therefore omitted.
