Dubai\u2019s police force has apparently started training its officers how to pilot a new flying motorbike, an initiative from the Russian-owned California-based Hoversurf first unveiled at last year\u2019s GITEX convention in the United Arab Emirates.\r\nThe vehicles are expected to be in action in just over a year\u2019s time, coinciding with Expo 2020 \u2013 the \u2018festival of human ingenuity\u2019 \u2013 which Dubai won the right to host.\r\nEach S3 2019 hoverbike costs $150,000, though Hoversurf has gifted Dubai police its first example to allow training to begin and to help get the promotional ball rolling. The two parties signed a partnership agreement in late 2017.\r\nBased on a prototype previously made from aluminium, the body of the \u2018electric vertical take-off and landing bike (EVTOL)\u2019 is a one-piece carbon-fibre composite, which both reduces the weight and adds structural rigidity. The new curb weight \u2013 now just 114 kg (253 lb) \u2013 means Hoversurf has been able to install a \u2018more capacious battery\u2019 discharging 12.3 kWh as part of the S3 2019\u2019s hybrid powertrain.\r\n\r\nThis also allows the drone, restricted by law to a 96 km\/h top speed (52 knots) and an altitude of 16 ft (5 metres), to fly for up to 40 minutes on what the company calls \u2018drone mode\u2019 (this drops to anywhere between 10 and 25 minutes when the pilot alights).\r\nAlso newly developed are the three-blade propellers, each of which is said to be 10 per cent quieter than the previous twin-blade design and smaller in diameter by 5 cm. Power comes from the as-of-yet unspecified \u2018new engines,\u2019 which provide 33 kW of power apiece (around 45 hp), while total thrust is said to be 364 kg (802 lbs).\r\nBear in mind this is not the first time Dubai police has thought big when it comes to promotion. Its \u2018Supercar Fleet,\u2019 purely promotional, already boasts a\u00a0Bugatti Veyron, an Aston Martin One-77, a Lamborghini Aventador and a BMW i8 among others. Until recently, Dubai police also held the Guinness World Record for the largest ever synchronized car dance, an accolade\u00a0only overhauled last month by the Nissan Patrol.
