Mini 3 in 1 Deluxe Scooter grows with the child. The scooter morphs through three distinct riding stages geared towards a child's developmental milestones. From ages 1-2, the first stage involves sitting and scooting with the ride-on seat and O-bar attachment. Then, removing the ride-on seat creates a stand-on scooter with a short O-bar. Finally, swapping the O-bar for the included T-bar adapts to the child’s height through age 5.
