United Bus was a bus manufacturing group created by DAF Bus and Bova (both from the Netherlands) in 1989.[1] It was later joined by Den Oudsten (Netherlands), Optare (UK), and DAB (Denmark).[2]


The collaboration between DAF and Optare led to the introduction of the DAF DB250 double-decker with Optare Spectra bodywork. This was the first partly low-floor double-decker and set the standard for future developments.[3]


Due to the 1991-1995 world recession, United Bus filed for bankruptcy in 1993, though the partners survived independently.[3]
