Four-wheel pedal power lets kids ride this go kart forward or in reverse, while the automatic balancing system and low gravity center help it stay stable as they play. The 39.8 x 24 x 24.5 in steel frame offers a big load-bearing capacity, supporting up to 66 lbs for children aged 3 and up. Wear-resistant rubber tires with anti-sliding textures provide grip on a variety of surfaces for both indoor and outdoor use. A fully enclosed chain keeps moving parts covered to help protect little hands and feet during riding. The ergonomic seat adjusts between two positions and pairs with a high backrest so kids can sit more comfortably as they steer with the 3-point steering wheel for an authentic driving experience.
