"A tricycle, often abbreviated to trike, is a human-powered (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. Tricycles are favoured by children and senior adults for their apparent stability versus a bicycle; however a conventional trike has poor dynamic lateral stability, and the rider must take care when cornering to avoid tipping the trike over. Unconventional designs such as recumbents have a lower centre of gravity so require less care." - (en.wikipedia.org 13.05.2021)
