context_page_description: A tricycle, often abbreviated to trike, is a human-powered three-wheeled vehicle.
  Some tricycles, such as cycle rickshaws 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.
context_section_description: Hand-crank trikes use a hand-operated crank, either as a sole source of power or a double drive with footpower from pedals and hand-power from the hand crank. The hand-power only trikes can be used by individuals who do not have the use of their legs due to a disability or an injury. They are made by companies including Greenspeed, Invacare, Quickie and Druzin.
  In case of paralysis of the legs, more speed and range of distance can be obtained by adding functional electrical stimulation to the legs. The large leg muscles are activated by electrical impulses synchronized with the hand cranking movement.
