WHAT ARE HOVERBOARDS?
Well, they are certainly different from the infamous "Back To The Future" hover board. The hover boards of 2015 don’t actually hover. Possibly, from a great distance, if you can’t see the rider’s feet or you’ve misplaced your glasses, it might look like someone’s hovering along. But in reality, they’re motorized transport devices that have a wheel, or two, upon which someone stands.
If you search on Amazon for the term “hover board,” you’ll be presented with a range of two-wheeled boards, although Amazon will also will also include results for "balance board" and “self-balancing scooter,” just to cover all the possible bases. This pretty much sums up how the boards work, too—you stand on one, lean forward or back to speed up and slow down, similar to the way you’d ride a standing scooter.
But unlike similar brands., the boards tend have a motor connected to each wheel, which lets each foot move individually—allowing for greater control over stability in the absence of a similar brand's pole and handle bars, and to help the rider steer left and right.
Also unlike similar brands, which you’re unlikely to encounter in 2015 unless you’re a mall cop or in a really obnoxious tour group, hover boards are growing in popularity.
Some useful stats: According to PC Advisor, most hover boards can accommodate about 220 pounds of weight. They can only hit top speeds of about 10 mph, and generally have a range of about 12 miles. The boards themselves generally weigh over 25 lbs.
