The Optare Solo is a low-floor minibus/midibus with one or two doors manufactured by Optare in the United Kingdom since 1998. The Solo name is a play on its low-floor status, the manufacturer marketing its vehicle as having an entrance that is "so low" from the floor, namely 200 mm (8 in) with kneeling suspension. In January 2012 Optare announced the end of production for the original Solo design with a modified Solo SR taking over.
