Ultimate Go-Kart™

The Best First Go-Kart for High Speed Fun

Buckle up for serious driveway thrills with Radio Flyer’s Ultimate Go-Kart™. Built for thrill-seekers ages 3 to 8, it features three forward speeds (2.5, 5, and 8 MPH), reverse gear, and automatic braking for smooth stops. The powerful 24V battery keeps the fun going longer, and the adjustable seat grows with your kiddo, so they can level up from rookie racer to neighborhood champ. Wide rear wheels are made to drift, spin, and slide, while grippy front tires keep steering smooth. Parent-friendly features like a seat belt, speed lock, and racing flag help keep things safe while the fun goes full throttle. A quick-adjust seat lever makes it easy to swap drivers—perfect for siblings or friends eager to take a turn. And the built-in sleep mode preserves battery life when kids inevitably jump to the next thing without powering down. Bonus: the onboard battery indicator lets you know when it’s time to recharge and refuel the fun.
