A two-wheeled vehicle simulation apparatus includes a vehicle simulator having a saddle which the driver sits on and handlebars operated by the driver, a mat switch laid on a floor in the vicinity of the vehicle simulator, and a monitor displaying information and images based on signals obtained from pedals, the handlebars, and the mat switch. Two or more of the mat switches are provided to independently sense respective placement of one or both feet on the floor by the driver. When two detectors substantially alternately detect placement of the driver's right and left feet on the floor, an image of a two-wheeled vehicle and a person walking the two-wheeled vehicle is displayed on the monitor. The vehicle simulator permits simulation of the action of a driver putting his/her foot on a road surface to achieve more realistic simulation.
