The BCI Citirider is an integrally-constructed high-capacity low-floor and low-entry single-deck and double-decker bus produced by BCI Bus since 2015. It is produced at BCI Bus' manufacturing facility in Xiamen, China. The double-decker bus, imported by bus dealer Ensignbus, is marketed as both the BCI Excellence and BCI Enterprise in the United Kingdom.
Launched in 2015 initially for the Australasian bus and coach market, the BCI Citirider single-deck bus was designed as a low-entry city bus suitable for both public bus and school bus operations. Assembled on an Alcoa aluminium frame, the front and rear fascias of the bus are made from fibreglass, while the side panels are all aluminium with bolts for ease of maintenance and replacement. BCI Citiriders also have a choice of a glass or aluminium roof.[clarification needed] In 2016, a low-floor double-decker variant of the Citirider, available on either a twin-axle or tri-axle chassis, was launched.
The BCI Enterprise was launched in the United Kingdom by Purfleet bus dealer and importer Ensignbus in July 2016. Built as standard with air conditioning, the Enterprise seats 98 passengers and differs by having a redesigned front fascia and a curved staircase as opposed to the Citirider's straight staircase. A twin-axle variant, marketed as the BCI Excellence, was launched by Ensignbus shortly afterwards.
A battery-electric single-deck variant, known as the Citirider E, was launched at the BusVic 2019 conference in Sydney in October 2019, developed in close partnership with Dutch electric bus manufacturer Ebusco. Capable of a range of up to 350 kilometres (220 mi) on a single charge and featuring 12 battery packs capable of 400 kWh of battery storage, the Citirider E also featured a restyled exterior and interior with a maximum carrying capacity of 45 seated and 20 standing passengers.
