The Low Floor Series (LFS) is a series of transit buses manufactured by Nova Bus for North American customers since 1996. It is produced in 40' rigid and 62' articulated (nominal) lengths with a variety of powertrains, including conventionally-fueled (diesel and natural gas), hybrid diesel-electric, and battery-electric. The LFS is the first transit bus designed by Nova Bus.
A transit bus (also big bus, commuter bus, city bus, town bus, urban bus, stage bus, public bus, public transit bus, or simply bus) is a type of bus used in public transport bus services. Several configurations are used, including low-floor buses, high-floor buses, double-decker buses, articulated buses and midibuses.
These are distinct from all-seated coaches used for intercity travel and smaller minibuses, for more flexible services.
