  • the controller may control the first driver to apply a driving force to at least one of the first elevating portion and the second elevating portion to correspond to an inclination angle of the inclined portion displayed on the display unit.
  • the bicycle simulator may further include a first speed measuring portion for calculating a ride speed from rotation of the front wheel, a second speed measuring portion for calculating a ride speed from rotation of the rear wheel, a (2-1) st driver for applying a rotational force to the front roller, and a (2-2) nd driver for applying a rotational force to the rear roller.
  • At least one of the (2-1) st driver and the (2-2) nd driver may apply a rotational force to the front roller or the rear roller, wherein a rotation speed of the front wheel or the rear wheel is constant.
  • the bicycle simulator may further include a belt connected between the front roller and the rear roller and transmitting a rotational force of any one of the front roller and the rear roller to the remaining one.
  • the bicycle simulator may further include a base portion in which the front roller and the rear roller are rotatably arranged.
  • the belt may be arranged on an outer side portion of the base portion and connect the front roller to the rear roller.

  • the bicycle simulator may further include an impact relief member arranged below the frame support portion and mitigating an impact applied to a rider.
  • the first elevating portion and the second elevating portion may each comprise a hollow cylinder, a piston inserted into the hollow cylinder and moving, and a fluid applying pressure to one end of the piston.
  • the bicycle simulator may further include an input unit for inputting a ride mode and a riding environment.
  • a method of operating a bicycle simulator includes inputting a ride mode, visually providing a preset riding environment including an inclined portion to a rider according to the ride mode, applying a driving force to at least one of the first elevating portion and the second elevating portion to correspond to an inclination angle of the inclined portion provided in the riding environment, and vertically moving a front end or rear end of the base portion in a direction perpendicular to the ground by a driving force applied from at least one of the first elevating portion and the second elevating portion.
  • a driving force may not be applied to the first elevating portion and the second elevating portion, and a first support point at which the front roller supports the front wheel and a second support point at which the rear wheel supports the rear wheel may be arranged on the same plane.
  • the method may further include measuring a rotational speed of the front wheel or rear wheel of the bicycle, and when the first elevating portion or the second elevating portion moves the base portion in a vertical direction, applying a rotational force to the front roller or the rear roller so that a rotation speed of the front wheel or the rear wheel is constant.
  • the rotational speed of the front wheel or the rear wheel may be measured by a speed measuring portion, and the rotational force applied to the front roller and the rear wheel may be generated by a (2-1) st driver and a (2-2) nd driver.
  • the front and rear wheels of a bicycle are supported on the same plane to match the actual riding environment, and thus, the same state as riding on the actual flat ground may be virtually experienced, and a realistic ride may be thereby enjoyed while excluding unnecessary power.
  • the rider on the bicycle may virtually experience various road conditions including an inclined portion, and a dynamic and realistic riding may be thus enjoyed.
