The buzz around hoverboards, or "self-balancing scooters," has been building momentum at just the right time to make them a highly sought after, though still pricey, holiday gift this year.
But don't expect to easily find them on the shelves of your local big box store before Christmas.
While retailers have been hustling to capitalize on the craze, they have been slowed down as they wade through patent disputes, a wide array of products flooding the market including copycats of questionable quality, and more basic things such as being able to secure enough stock for the holidays.
The curious contraptions, a sort of modern spin on skateboards, are two-wheeled, battery-powered vehicles similar to a Segway but without any handles. Despite the name, they don't levitate. Hoverboards first started popping up earlier this year at such trade shows as the Consumer Electronics Show and the annual toy fair in New York.
They have been on a meteoric rise since then as they were quickly adopted as a quirky and cool accessory of celebrities. The rapper Wiz Khalifa made headlines when he was arrested for riding one at the Los Angeles airport over the summer. Justin Bieber has posted videos of himself doing spins on a hoverboard on his Instagram account. And Jamie Foxx rolled onto the "Tonight Show" on one and let a wobbly Jimmy Fallon try it out, too.
Some of the first, more well-known models such as IO Hawk and PhunkeeDuck sell for upward of a $1,500. But now there are lots of knockoffs and lower-priced versions available for less than half that price.
The fact that there's not a single major brand in the marketplace makes it more challenging for retailers to immediately hop on the trend, said Carol Spieckerman, a retail consultant. And with some reports of some cheaper versions catching on fire in England when left plugged in overnight, retailers are likely t o be a bit more cautious in wanting to wait for some safety testing and quality control.
On top of that, there are ongoing disputes over patents. Most prominently, billionaire Mark Cuban had threatened to sue companies that might infringe on the patent of one of the hoverboard companies he was backing. But the situation has been rapidly changing. Cuban told BuzzFeed about a week ago that he's planning to make his own boards, especially amid safety concerns.
