Referring to FIG. 12 , the rider according to an example may input the model of the bicycle 10 mounted on the bicycle simulator 1 or the distance between the front wheel 12 and the rear wheel 13 of the mounted bicycle. (S110) For example, the model of the bicycle 10 mounted on the bicycle simulator 1 according to an example may be different. In particular, the length of the bicycle frame 11 connected between the front wheel 12 and the rear wheel 13 of the bicycle may be different depending on the model of the bicycle 10 . In this case, the rider may input the model of the bicycle 10 mounted through the input unit 80 . Distance information between the front wheel 12 and the rear wheel 13 of the bicycle according to the model of the bicycle 10 may be input to the storage unit 90 according to an example.

13 is a side view of a bicycle simulator according to another embodiment. 14 is a block diagram of a bicycle simulator according to another embodiment.

In the bicycle simulator 1 according to the above-described embodiment, the rider must directly drive the mounted bicycle 10 . However, in a situation in which the rider must directly drive the bicycle 10, high-speed driving, for example, high-speed driving such as 100 km/h per hour cannot be experienced. The bicycle simulator 1 ′ according to another embodiment may include a third driving unit 95 and a fourth driving unit 96 . Accordingly, the rider may experience various driving environments, such as a high-speed driving environment, without directly driving the bicycle 10 . Among the components included in the bicycle simulator 1' shown in FIGS. 13 and 14, the remaining components except for the third driving unit 95 and the fourth driving unit 96 are the bicycle simulators shown in FIGS. 1 and 2 ( Since it is substantially the same as the components included in 1), description is omitted here for convenience of description.

13 and 14 , the bicycle simulator 1 ′ according to another example includes a third driving unit 95 connected to the first connecting rod 630 and a fourth driving unit 96 connected to the second connecting rod 670 . ) may be included. The third driving unit 95 according to an exemplary embodiment may transmit a rotational force rotating about the first direction (X direction) to the first connecting rod 630 . The rotational force transmitted to the first connection rod 630 may be transmitted to the front wheel roller 410 through the 1-2 gear unit 620 , the 1-1 gear unit 610 , and the rotation shaft 411 . Accordingly, the front wheel roller 410 may rotate about the second direction (Y direction), and the rotational force may be transmitted to the front wheel 12 supported by the front wheel roller 410 through frictional force.

The fourth driving unit 96 according to an exemplary embodiment may also transmit a rotational force rotating around the first direction (X direction) to the second connecting rod 670 . The process in which the rotational force is transmitted from the second connecting rod 670 to the rear wheel roller 510 via the 2-2 gear unit 660, the 2-1 gear unit 650 and the rotation shaft 511 is performed by the third driving unit ( 95), so the description is omitted here.

As described above, since rotational force can be applied to the front wheel roller 410 and the rear wheel roller 510 by the third driving unit 95 and the fourth driving unit 96, the rider has a higher speed than the rotational force that he or she can generate. You can experience riding the bicycle 10 .

Referring to FIG. 15 , the rider according to an example may input the model of the bicycle 10 mounted on the bicycle simulator 1 or the distance between the front wheels 12 and the rear wheels 13 of the mounted bicycle. (S210) Next, the control unit 70 controls one of the front wheel roller 410 or the rear wheel roller 510 according to the input model of the bicycle 10 or the distance between the front wheel 12 and the rear wheel 13 of the mounted bicycle. A control signal for moving one or more in the first direction (X direction) may be generated. (S220) Next, at least one of the front wheel roller 410 and the rear wheel roller 510 may move in the first direction (X direction). (S230) Since steps S210 to S230 described above are substantially the same as steps S110 to S130 shown in FIG. 12 , a description thereof will be omitted.

Next, the rider may select a driving mode through the input unit 80. (S240) As an example, the driving mode selected by the rider may be high-speed driving, for example, high-speed driving of 100 km/h or more. However, the speed described above is exemplary, and a driving mode of any other speed that cannot be directly driven by the rider may also be selected.

Next, a control signal for generating a driving force may be generated using the third driving unit 95 and the fourth driving unit 96 . (S250) The control unit 70 according to an embodiment may transmit a control signal to the third driving unit 95 and the fourth driving unit 96 according to the input driving mode. The third driving unit 95 and the fourth driving unit 96 receiving the control signal may generate a driving force corresponding to the driving mode.

Next, the front wheel roller 410 and the rear wheel roller 510 may rotate at high speed by the driving force transmitted from the third driving unit 95 and the fourth driving unit 96 . (S260) The front wheel roller 410 and the rear wheel roller 510 according to an embodiment may rotate at a high speed according to the driving force transmitted from the front wheel roller 410 and the rear wheel roller 510 . Accordingly, the front wheel 12 and the rear wheel 13 supported by the front wheel roller 410 and the rear wheel roller 510 through friction, respectively, may also rotate at high speed. As a result, riders can experience high-speed driving outside the range that they can drive on their own. At this time, as shown in FIG. 16 , the current driving situation, for example, the virtual driving situation according to the driving speed, is displayed through the display device 97, so that the rider can experience a more realistic driving environment.
