CityBus is one of the three major bus operators in Hong Kong, it provides both franchised and non-franchised bus services. The franchised route network serves mainly Hong Kong Island, cross-harbour routes (between Hong Kong Island and Kowloon/New Territories), Ocean Park, North Lantau (Tung Chung and Hong Kong Disneyland) and Hong Kong International Airport. The non-franchised routes serve mainly City One Shatin.

The Olympian has been part of the Citybus fleet since 1985, when Citybus purchased its first air-conditioned double-deck bus. Since then, over 500 Olympians have been purchased all of which are air-conditioned. These buses work on a wide variety of routes in the territory, including high frequency local routes and longer distance express routes.

Route 930 which is featured on this model, was one of the first to operate the new Western Harbour Crossing and now carries almost 300,000 passengers per month. Fleet No 521 entered service on 19th February 1997.
