Children's ride-on vehicles are disclosed. In some embodiments, the vehicle may include first and second mechanical members, with the second mechanical member configured to move between a concealing position, in which the second mechanical member conceals a portion of the first mechanical member, and a revealing position, in which the second mechanical member does not conceal the portion of the first mechanical member. In some embodiments, a biasing member urges the second mechanical member toward the concealing position. In some embodiments, a user input device permits a child to lock the first mechanical member in one of a retracted position and an extended position.
