Police in Dubai may soon have access to functional hoverbikes, according to AutoBlog, which reported the Dubai Police unveiled the new technology in conjunction with Russian company Hoversurf at the Gulf Information Technology Exposition last week.
Per Autoblog, the Scorpion hoverbike is capable of flying approximately 16 feet (five meters) in the air, moving at a speed of 43 miles per hour (70 kilometers per hour) and carrying 660 pounds (300 kilograms) of gear. Its thus capable of clearing traffic-packed roads, but one serious drawback is the units limited, 25 minute charge capacity. The Scorpions rotor blades also look ready to chop through anything it might bump into, like humans, and sort of looks like it is as dangerous for the operator to fly as for anyone who might wander into its path.

In the video, sometimes the rotors are caged and sometimes they are not.
Also, with just 25 minutes capacity, I would back them up with some sort of "carrier": A van with a docking-station on the roof, where the hoverbike can be parked and charged from batteries transported in the van.
Or how about a trailer-truck as a hoverbike-carrier? Enough space for several hoverbikes on the roof of the trailer and inside the trailer there's place for batteries, maintenance and command. (The Formula One racing-teams use customized trailer-trucks as mobile repair-shops. There's for example a german company that builds these special trailers. A similar idea can be used for hoverbikes.)
