No batteries, gears or pedals--just a fun, encouraging and progressive start to bicycle riding. Its unique design encourages balance, coordination and motor skill development while offering a fun ride. Children as young as 18 months can enjoy the freedom of riding without the added complication of training wheels or anxiety of having to hold their balance too long, too early. Wide wheels ensure that PlasmaBike doesn't tip over in a stopped or stationary position, limited steering range enhancing balancing capabilities, and provides a smoother transition to a conventional 2 wheel ride. Weighs less than 8 lbs and supports up to 55 lbs.
