According to the present invention, since the driving unit can assist the rotation of the roller in contact with the bicycle wheel at the start of the exercise, the load on the rider's knee is reduced, so anyone of any age or gender can safely use it.

In particular, if a roller with a reduced outer diameter is applied to reduce vibration, the initial rotation of the roller becomes more difficult. Since the roller is rotated by using it together, it is possible to prevent the occurrence of a problem of poor usability due to the reduction of the outer diameter of the roller.

In addition, since the connection between the driving motor and the roller is separated in a predetermined speed range, the driving environment of the outdoor level can be provided.
