For kids aged less than 6 years, a three wheel toy is a must whether you are buying a normal or an powered one, although the latter are better for older kids only. The three wheels as opposed to two provide better stability which is essential for a kid this young as they cannot balance themselves. The additional wheel is usually on the front and the rear wheel is made wide to match this stability. For this reason, the deck is also wider as compared with two wheeled models. You will often read the term lean to steer for these toys for kids. It means that your son or daughter will have to lean to turn the thing and the handlebar plays no role in this. This technique is there to improve support as well as their intuition about directions. Children as young as 2 years old can scoot, so parents should buy them these toys because they are fun and help improve their walking and balancing.
