The Optare Solo is a low-floor midibus manufactured by Optare in Leeds, UK since 1997. The name "Solo" is a play on the low-floor status of the bus, the manufacturer believing its vehicle having an entrance that is "so low" from the floor, namely 200 mm with kneeling suspension. The innovative design, featuring a front axle ahead of the entrance, gained the bus a "Millennium Product" award, along with "The Queen's Award for Enterprise 2000".
