The sleek, innovative design of the PlasmaCar features a patented safety seat, polypropylene wheels, and is kid powered; kid approved! Sit with both feet on the footrests, turn the steering wheel and away you go. Turn and navigate in small spaces indoors, and ride outdoors on sidewalks, pathways, and any other safe, smooth, flat surface. The award-winning PlasmaCar is easy to operate, and helps your child develop coordination, balance, and motor skills while harnessing the natural forces of inertia, centrifugal force, gravity, and friction. PlasmaCar is adult-friendly too: it doesnt require an expensive power source that needs constant replacement, it provides kids with plenty of exercise, and it is quiet, the only sound youll hear is the sound of the wheels. Fully assembled: 31 x 14 x 16.
