PlasmaCar is a ride-on toy that uses the natural forces of inertia, centrifugal force, friction and of course all that power your child has stored inside. I really appreciate that you don’t need any batteries to operate this car. You also don’t have to mess around with gears or pedals. Your child can sit back on their patented safety seat and enjoy their fun ride! You can use this indoors or outdoors, but it’s best (no matter where you use it), to be on a flat surface. Great for ages 3+ and up to 220 lbs! That’s right, if mom and dad want to give it a go, no worries!
