As of 2015, more than 3,500 Flexity vehicles are in operation around the world in Europe, Asia, Oceania, and North America in 100 cities among 20 countries internationally.

Manufactured from corrosion-resistant carbon steel and featuring driver's cabs made with glass-reinforced plastic,[4] they have a modular design that is customizable to meet specific operators' demands, including a variety of track gauges and voltages.

A low-floor design with multi-purpose areas is standard on most models, allowing easy access to the vehicles for wheelchair users.

Eurotram was originally conceived by Socimi of Italy as a distinctive, train-like tramcar with large windows and modules with both powered and unpowered bogies.

Although this particular model is only used in Saarbrücken,[12] a recent order has been made for dual-voltage Flexity Swift vehicles in Karlsruhe, where the tram-train concept was pioneered.

Designed for the Transit City network in Toronto, Kitchener-Waterloo and other LRT projects in Ontario,[15] the model has been selected for Edmonton's Valley Line[16] and is being marketed by Bombardier for future orders within North America.

[20] A derivative of the Flexity Outlook was created for the Toronto streetcar system to replace the aging CLRVs and ALRVs built by UTDC.

Bombardier has also manufactured other models of tram which they do not place in the Flexity family,[17] including the Cobra for Zürich and the Incentro for Nantes and Nottingham.
