The Villiers Mk 3K was a popular and versatile autocycle produced by Villiers Engineering Company in the United Kingdom from the late 1920s to the early 1930s. It was known for its robust construction, reliable performance, and relatively affordable price. The Mk 3K was a lightweight, single-seater vehicle powered by a Villiers 98cc two-stroke engine, capable of reaching speeds of around 30 mph. The engine was mounted in a sturdy steel frame, with a chain-driven rear wheel. The Mk 3K featured a simple but effective design, with a foot-operated clutch and a two-speed gearbox.

Despite its relatively short production run, the Villiers Mk 3K remains a significant vehicle in the history of autocycles. It represents a pioneering period in the development of personal transportation, a time when compact, reliable vehicles were just starting to become a part of everyday life. Today, the Mk 3K is a sought-after collector's item, admired for its historical significance and for its role in shaping the future of motorcycling.
