Patent ID: 8353806

Claim:
A speed race apparatus using stationary bikes, comprising: a first stationary bike for a first racer, including a first pedal, a first resistance adjuster being capable of changing a first resistance against a first pedaling by the first racer, and a first button for outputting a first signal; a second stationary bike for a second racer, including a second pedal, a second resistance adjuster being capable of changing a second resistance against a second pedaling by the second racer, and a second button for outputting a second signal; a display including a plurality of first LEDs forming a first race track for the first racer, and a plurality of second LEDs forming a second race track for the second racer; and a controller controlling the plurality of first LEDs to show the change of the first racer's location in the first race track according to speed and duration of the first pedaling, and controlling the plurality of second LEDs to show the change of the second racer's location in the second race track according to speed and duration of the second pedaling, wherein the first race track includes a first incident section in which the first resistance against the first pedaling is changed, the controller maintains the first resistance in case the first signal generated by the first button is received in the first incident section but increases the first resistance in case the first signal is not received in the first incident section, wherein the second race track includes a second incident section in which the second resistance against the second pedaling is changed the controller maintains the second resistance in case the second signal generated by the second button is received in the second incident section but increases the second resistance in case the second signal is not received in the second incident section.
