The Mini Micro 3in1 is the quality ride-on toy and scooter that 'grows' with children from age 1 to 5. Start with the ride-on seat at age 1, moving to a stand-on scooter with short O-bar at age 2, and convert to the Mini Micro with TBar at age 3 . Polyurethane wheels make for a smooth, quiet ride, and the stable, upright design, low deck, soft edges, and rear spoon brake provide an extra measure of security. New to the United States, the Seat and O-bar now include (2) height settings, allowing the Seat accessory to be used by taller toddlers. For children up to 44lbs.
