Abstract: A ride-on toy includes a handle unit; a front leg unit including a front leg and a front wheel mounted to the front leg; a rear leg unit including a rear leg and a rear wheel mounted to the rear leg; a pedal unit; a saddle unit; and a chassis. In a first state, in response to a first downward force applied to the saddle unit and a forward force applied to the handle unit, the front leg moves with the front wheel forward and away from the rear leg, and the rear leg stays still. In a second state, in response to a second downward force applied to the pedal unit and a rearward force applied to the handle unit, the rear leg moves with the rear wheel forward and toward the front leg, and the front leg stays still.

Abstract: A steering device includes a handle unit; a steering connection piece; a joint connecting the handle unit to the steering connection piece; a steering connection rod movably connected to the steering connection piece; and a pair of steering rods each rotatably connected to the steering connection rod. In response to a rotation of the handle unit about a first rotational axis, the joint is configured to force the steering connection piece to rotate along with the handle unit about the first rotational axis to cause a shift of the steering connection rod along a first direction perpendicular to the first rotational axis, and the pair of steering rods is configured to rotate about second and third rotational axes, respectively, in response to the shift of the steering connection rod.

Abstract: A one-way rotating device includes a wheel configured to rotate about a center axis thereof toward a front side or a rear side of the wheel; a wheel bracket mounted to the wheel; and a stop ring mounted to the wheel bracket at a fixed position above the center axis of the wheel and contacting a circumferential surface of the wheel on the front side or the rear side of the wheel. The stop ring is configured to stop the wheel from rotating in a direction toward the front side or the rear side.
