Fisher Price Green Power Wheels Dune Racer is the perfect summer ride. It has off-road tires that provide maximum traction in any trail condition and a powerful traction drive system. Whether your child is a beginner or an advanced driver, the Dune Racer's two driving speeds can accommodate him or her. This little monster features an electronic power lock braking system that automatically stops the vehicle when your child's foot lifts from the pedal. A shifter with high-speed lockout for beginners provides custom control of driving speeds - low speed for normal 2-1/2-mph cruising, and high speed for maximum 5-mph in racing mode. It can also shift into reverse for convenient backing up. The Dune Racer offers hours of fun, it comes with a 12-volt battery and a charger and should last at least 2 hours with 2 kids onboard.
