Abstract
Children's ride-on vehicles having a drive assembly that is selectively configured between a plurality of drive configurations, such as responsive to user inputs via user input devices, and a ground detection system that is adapted to detect when at least one of a plurality of wheels loses contact with the ground surface. The ground detection system may be adapted to restrict the plurality of drive configurations responsive thereto. This restriction may be automatic responsive to loss of contact of the at least one of the plurality of wheels with the ground surface, and it may be made regardless, or independent, of user inputs that otherwise would select and/or enable one of the restricted drive configurations.
