A quadracycle (also spelled quadricycle) is a four-wheeled human-powered land vehicle. It is also referred to as a quadcycle, pedal car, or four-wheeled bicycle among other terms.
Quadracycles have been in use since 1853 and have grown into several families of vehicles for a variety of purposes, including tourist rentals, pedal taxis, private touring, mountain and industrial use.
A cart or dray (Australia and New Zealand) is a vehicle designed for transport, using two wheels and normally pulled by draught animals such as horses, donkeys, mules and oxen, or even smaller animals such as goats or large dogs.
The word cart is often used interchangeably with trolley (especially in the UK) and wagon (especially in the US). Over time, the word "cart" has expanded to mean nearly any small conveyance without regard to number of wheels, load carried, or means of propulsion. The word car has often been modified to cart through colloquialization. For example, several small sport and hobby cars carry "cart" in their name such as pedal carts (manually pedaled), soap-box carts (gravity run), and go-carts (gas engine). Similarly, golf cars are more commonly known as golf carts.
