Introduction in Bronze-Age Europe

As David W. Anthony writes in his book The Horse, the Wheel, and Language, in Eastern Europe, the earliest well-dated depiction of a wheeled vehicle (a wagon with two axles and four wheels) is on the Bronocice pot (c. 3500 BCE). It is a clay pot excavated in a Funnelbeaker settlement in Swietokrzyskie Voivodeship in Poland. The oldest securely dated real wheel-axle combination in Eastern Europe is the Ljubljana Marshes Wheel (c. 3150 BCE).
