Abstract: This is a baby toy which matures with the baby from infancy through childhood, accelerating and enhancing baby's mental and physical development, encouraging fitness, and helping baby develop coordination skills at an earlier age. The toy is an enhanced tricycle with stepwise removable parts, which comprise one or more of the following: push and guide handle, foot rest, back support, seat belt, left and right restrainers with or without spacers which allow adjustment of a snap-in front restrainer, the side restrainers also preventing the handlebars from being rotated by the occupant, child proof parking brake to allow the tricycle to be safely stored or parked, and a sun shade. The push and guide handle allows pushing while walking behind the toy vehicle, guiding and controlling the direction of toy's travel, while allowing the occupant child to participate in the propulsion and guidance processes as soon as the child is ready.
