A leg actuator mechanism, a method of manufacturing the leg actuator mechanism, and a doll implementing a leg actuator mechanism is provided. The leg actuator includes an upper leg mechanism comprising a hip end and an opposing knee end. The leg actuator also includes a lower leg mechanism comprising a first end and an opposing second end, wherein the first end of the lower leg portion is operably coupled to the knee end of the upper leg portion. The leg actuator further includes a follower mechanism. The follower mechanism includes a mounting defining a follower pathway configured to receive a follower joint. The follower mechanism also includes an upper follower connector and a lower follower connector. The follower mechanism moves at least one of the upper leg mechanism or the lower leg mechanism when activated.

The present invention relates to a convertible child cycle, which includes a cycle frame extending in a horizontal longitudinal direction and curved upwardly. The cycle frame is formed with a slot facing downward. The cycle frame is further formed with a first installation connector adjacent to the front end, a second installation connector adjacent to the rear end, and a third installation connector disposed between the first and second installation connectors. The child cycle further includes a headset assembly and a rear fork assembly releasably engaged the first and the second installation connectors, respectively. With the growth of a preschool child rider, the invention may be readily converted into a tricycle, a balance bicycle or a bicycle by combining the cycle frame with various accessory parts, thereby satisfying the recreation needs of the preschool child at different developmental stages.

A ridable kart having a front portion rotatably coupled to a rear portion. The front portion includes an inner surface that is adjacent to an outer cover portion and the two surfaces move relative to one another. The outer cover portion includes window portions or openings through which a portion of the inner surface is visible. The inner surface includes a visual feature that is visible through the window portions and the visual features moves relative to the window portions when the front portion rotates relative to the rear portion.

A ride-on vehicle, such as for a child, includes a vehicle body and one or more wheels that support the vehicle body relative to a surface. At least one of the wheels includes a hub motor arrangement that provides a drive torque for propelling the vehicle. The hub motor arrangement includes a housing defining an interior space. An axle or other mounting element(s) define an axis of rotation of the housing. Preferably, the axle or other mounting element(s) do not pass completely through the housing. A motor drives the housing through a transmission. Preferably, the motor is a standard, compact motor that is positioned on the axis of rotation and can be laterally offset from a central plane of the housing. In some embodiments, a traction element is carried directly by the housing.
