Tricycle

Three-wheeled self-powered vehicle

A tricycle, often abbreviated to trike, is a human-powered (or gasoline or electric motor-powered or assisted, or gravity-powered) three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise.
