Hoverboards may be a new fun, cool and quick way to travel, but according to the New York Police Department, they are also illegal.

Hoverboards quickly became one of the must-have gadgets of 2015, after a number of celebrities, including Justin Bieber, Chris Brown and Wiz Khalifa, were seen zipping around on the futuristic devices. However, New York police are advising users to pump their brakes, or they could end up with a $500 fine, reports WABC-TV.

On Monday, the 26th NYPD precinct in Manhattan sent out a tweet that has since been deleted, saying that that two-wheel, hands-free motorized device violates a NYC Admin Code 19-176.2, reports the New York Daily News.

However, it was later revealed that the code only bans motorized scooters that have "handlebars" and are "capable of exceeding fifteen miles per hour." Hoverboards, on the other hand, do not come with a handlebar, and travel between 6 and 10 miles per hour.

But just when it seemed like it was safe to cruise on a hoverboard again, the NYPD issued a new statement, confirming that the vehicles are indeed illegal because they cannot be registered at the Department of Motor Vehicles.

According to the New York State Vehicle and Traffic Law, it is mandatory for "all motor vehicles to be registered with the NYS DMV." If they cannot be registered, then "they are not permitted," reads the statement, reports PIX11 News.

Other vehicles restricted from being registered in New York include mini bikes, off-road motorcycles, go-karts, golf carts and motor-assisted bicycles. Even though the hoverboard is a new technology that was not named on the list, the city's transportation department said Wednesday that motorized self-balancing devices like hoverboards are illegal as well.

In response, Marcos Avila, 32, of Jackson Heights said the news about NYC law banning hoverboards comes as a major disappointment.

"It's really going to disrupt my life," he told the New York Daily News. "That was my go-to device."
