Ikarbus is a Serbian bus manufacturer based in the Belgrade urban municipality of Zemun. The company was originally established as an aircraft manufacturer in 1923 under the name “Ikarus – the first Serbian airplane car and engine industry Kovacevic and Co” in Novi Sad by Dimitrije Konjovic brothers Dusan and Milivoj Kovacevic Djoka Radulovic and Josif Mikl. The company changed its name to Ikarbus in 1992 due to name usage conflicts with the Hungarian bus manufacturer with the same name.
