The Can-Am Spyder ("Spyder") is a three-wheeled motorcycle manufactured by Can-Am motorcycles, a division of Bombardier Recreational Products. The vehicle has a single rear drive wheel and two wheels in front for steering, similar in layout to a modern snowmobile. The Spyder uses an ATV-like chassis. The manufacturer refers to it as a "roadster," but in technical terms, it is more of what has been traditionally called a trike.

A motorized tricycle, motor trike, or motortrycle is a three-wheeled vehicle based on the same technology as a bicycle or motorcycle, and powered by an electric motor, motorcycle, scooter or car engine.
