At the age of 2 Evan received his Lightning McQueen Powerwheel for christmas of 2009. After three years of use he had worn through the plastic wheels. We decided to upgrade the oem plastic wheels to metal rims with rubber tires. From that point more modifications were added every few weeks. Now, Evans Lightning McQueen Powerwheel is equipped with an aluminum back half chassis, dual sealed gel batteries with an output of 24 volts, a 500 watt .66 horsepower electric motor, disk brake, throttle modulated variable speed control with reverse and sparco battery cut off switch.
