    • A stationary bike can control a display content appearing on a screen in accordance with its operation. The stationary bike basically includes a body, a handlebar rotatably attached to the body and a control unit controlling the display content on the screen, and is characterized by a restoring mechanism restoring the handlebar to an initial position. The restoring mechanism is configured with a coil spring wound around an outer circumference of a shaft, a hook securing one end of the coil spring to the shaft, and a hook securing the other end of the coil spring to a tubular member. The hooks are respectively engaged with a bolt secured to the shaft and with a bolt secured to the tubular member.
