Four play modes share one PP frame so kids can use this 4-in-1 ride-on as a foot-to-floor car, a push walker, a push car or a ride-on with trailer, adapting as they grow from ages 1.5-5. The ride-on with trailer features an 8 x 7.5 in seat, a 7 x 5.5 in under-seat compartment opening and a 5.5 x 4 x 4.5 in inner trailer for toys. Fully enclosed 5-in wheels, a low center of gravity, widened wheelbase and 50° steering limit help resist tipping. The seat supports up to 45 lbs, while anti-slip footrests, a backrest and a handlebar help kids maintain balance. A music button plays 10 songs to make riding more engaging.
