Content:  1 m in diameter, was uncovered at the Must Farm site in East Anglia in 2016. The specimen, dating from 1,100 to 800 BCE, represents the most complete and earliest of its type found in Britain. The wheel's hub is also present. A horse's spine found nearby suggests the wheel may have been part of a horse-drawn cart. The wheel was found in a settlement built on stilts over wetland, indicating that the settlement had some sort of link to dry land. Although large-scale use of wheels did not occur in the Americas prior to European contact, numerous small wheeled artifacts, identified as children's toys, have

On the other hand, Mesoamericans never developed the wheelbarrow, the potter's wheel, nor any other practical object with a wheel or wheels. Although present in a number of toys, very similar to those found throughout the world and still made for children today ("pull toys"), the wheel was never put into practical use in Mesoamerica before the 16th century. Possibly the closest the Mayas came to the utilitarian wheel is the spindle whorl, and some scholars believe that these toys were originally made with

Some argue that the primary obstacle to large-scale development of the wheel in the Americas was the absence of domesticated large animals that could be used to pull wheeled carriages. The closest relative of cattle present in Americas in pre-Columbian times, the American bison, is difficult to domesticate and was never domesticated by Native Americans; several horse species existed until about 12,000 years ago, but ultimately became extinct. The only large animal that was domesticated in the Western hemisphere, the llama, a pack animal, but not physically suited to use as a draft animal to

It is thought that Nubian waterwheels may have been ox-driven. It is also known that Nubians used horse-drawn chariots imported from Egypt. The wheel was barely used, with the exception of Ethiopia and Somalia, in Sub-Saharan Africa well into the 19th century, but this changed with the arrival of the Europeans. The spoked wheel was in continued use without major modification until the 1870s, when wire-spoked wheels and pneumatic tires were invented. Pneumatic tires can greatly reduce rolling resistance and improve comfort. Wire 
Title: Wheel construction
Content:  The wheel is one of the most important inventions, but its inventor and exact date of invention are not yet known. The oldest known wheel was excavated from Mesopotamia, believed to be 5500 years old. This earliest wheel was a potter's wheel, used in the city of Ur in Mesopotamia (present-day Iraq), invented by Mesopotamians (also known as Sumerians) around 3500 BCE. The earliest known use of the wheel for transportation is in Mesopotamian chariots about 3200 years ago. Egyptians developed wheels with spokes about 2000 years ago, followed by Europeans some 1400 years ago. Another source says the oldest wheel used for transportation, with a radius of 27.5 inches (70 centimeters), was discovered in 2002, about 12.5 miles (20 kilometres) south west of Ljubljana in Slovenia, and is believed to be 5200 years old.
Title: Wheel
Content: 4500–3300 BCE (Copper Age): invention of the potter's wheel; earliest solid wooden wheels (disks with a hole for the axle); earliest wheeled vehicles; domestication of the horse ; 3300–2200 BCE (Early Bronze Age) ; 2200–1550 BCE (Middle Bronze Age): invention of the spoked wheel and the chariot The place and time of the invention of the wheel remains unclear, because the oldest hints do not guarantee the existence of real wheeled transport, or are dated with too much scatter. Mesopotamian civilization is credited with the invention of the wheel. However, unlike other breakthrough inventions, the wheel cannot be attributed to a single nor several inventors. Evidence of

Two types of early Neolithic European wheel and axle are known; a circumalpine type of wagon construction (the wheel and axle rotate together, as in Ljubljana Marshes Wheel), and that of the Baden culture in Hungary (axle does not rotate). They both are dated to c. 3200–3000 BCE. Some historians believe that there was a diffusion of the wheeled vehicle from the Near East to Europe around the mid-4th millennium BCE. Early wheels were simple wooden disks with a hole for the axle. Some of the earliest wheels were made from horizontal slices of tree trunks.

Estimates on when this may have occurred range from 5500 to 3000 BCE with most experts putting it closer to 4000 BCE. The oldest artifacts with drawings depicting wheeled carts date from about 3500 BCE; however, the wheel may have been in use for millennia before these drawings were made. More recently, the oldest-known wooden wheel in the world was found in the Ljubljana marshes of Slovenia. The invention of the wheel revolutionized trade and war. It did not take long to discover that wheeled wagons could be used to carry heavy loads. The 
Title: Wheel gymnastics
Content:  The wheel was invented in 1925 by Otto Feick in Schönau an der Brend. The grandson of a blacksmith, Feick was inspired by the memory of an event from his childhood in Reichenbach, when he had tied sticks between two hoops that his grandfather had made and rolled down a hill. He filed for a patent as "wheel-gymnastic and sports equipment". He had invented the wheel in Ludwigshafen am Rhein c. undefined 1920–1922, on the grounds of the VSK Germania, a sports club, of which he was the founding chairman. The patent was issued on 8 November 1925; the name "Rhönrad" has been registered and protected since 1926 
Title: Spoke
Content:  The spoked wheel was invented to allow the construction of lighter and swifter vehicles. Earliest physical evidence for spoked wheels were found in Sintashta culture, dating to c. undefined 2000 BC. Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater part of three centuries. They moved deep into the Greek peninsula where they joined with the existing Mediterranean peoples to give rise, eventually, to classical Greece after the breaking of Minoan dominance and consolidations led by pre-classical Sparta and Athens. Neo-Chalcolithic/proto-historic period (2nd mill. BCE) paintings in various regions of India such as Chibbar Nulla, Chhatur Bhoj Nath Nulla, Kathotia, etc. depict the usage of chariots with spoked wheels. Celtic chariots introduced an iron rim around the wheel in the 1st millennium BC. The spoked wheel was in continued use without major modification until the 1870s, when wire wheels and rubber tires were invented.
