Bay Zoltán Flike


Bay Zoltán Nonprofit Ltd
Budapest, Hungary

The Hungarian research institute, Bay Zoltan, created a one passenger electric vertical takeoff and landing (eVTOL) hoverbike called the Flike (portmanteau of fly and bike). The Flike is a personal tricopter for sport or Urban Air Mobility (MOB). The institute was established in 1992 by the National Committee for Technological Development (OMFB) on behalf of the government as a foundation. It was transformed from a foundation into a non-profit company in 2011. The Flike aircraft shown above was designed by Robert Kovacs, who is based in Hungary.

According to the European Union website: "The aim of Hungary's largest and most successful state-owned institution of applied research, Bay Zoltán Nonprofit Ltd., which is named after the famous physicist, is to improve the competitiveness and efficiency of enterprises in Hungary through successful innovation and technology transfer, in close cooperation with domestic and leading foreign partner institutions."

The Flike technology demonstrator has an open cockpit, a maximum speed of 100 km/h (62 mph), a maximum payload 100 kg (220 lb), a flight time of 30-40 minutes, has six propellers, its power source is batteries and has fixed landing struts.

The company achieved its first crewed flight on March 7, 2015 at Miskolc Airfield in northeast Hungary. On April 30, 2015, it accomplished its first manned flight of more than 1 minute.

As of March 2021, we have not found any additional information on the status of the Flike project.
