Big,bold, and ready for off-road action, the 12v 4 Wheel Drive Kids Electric Car is packed with features including a working horn, working headlights, and a built-in audio system with an AUX Input, Micro SD / Regular SD card slot, and a USB Thumb Drive input so young drivers can blast their favorite tunes. This large ride-on is designed for ages between 1 and 7, and unlike most 12V ride-ons, is a fully 12V system, right down to the motors.
