Bilbobus is part of a wider transport network operated by the Basque government, recent additions to which include the Metro Bilbao underground and the tram line.

They link the Renfe, Euskotren Trena and FEVE train services and are heavily integrated by means of the Barik card to provide ease of movement in the city.

All have a low lower floor, so they are adapted for people with reduced mobility (PRM), and have electronic panels inside to inform of the next stop, as well as the temperature, date and time.

In addition, the units incorporate surveillance cameras both to avoid violent situations inside the bus, and to record the route along which the vehicle travels and thus be able to detect possible conflict points that cause delays (cars in double file, poorly placed containers, narrow streets, etc.)

In 1992, the first low-floor units (Van Hool A-300); as a curiosity, these vehicles, from Belgium, participated in the Barcelona 92 Olympics, transporting disabled people to the venues where the games took place.
