Tricycle - online puzzles

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.
