List of Douglas motorcycles (short, easy-to-understand version)

Douglas was a Swiss company that built motorcycles from the early 1900s until the 1960s. This simplified list highlights the main types and time periods of their bikes. It’s not a complete catalog, and you’re welcome to add more models or details.

- Early bikes (1900s–1910s): Simple, lightweight motorcycles with single or early twin-cylinder engines. Used for daily riding and early racing.

- World War I era (1914–1918): Rugged, reliable small bikes made for military use and quick transport.

- Interwar years (1920s–1930s): More engine choices and better chassis. Sidecar versions became common, expanding versatility.

- Prewar to World War II (late 1930s–1940s): Road bikes with improved reliability and mid-sized engines for everyday riding and sport.

- Postwar era (1945–1950s): Focus on affordable, easy-to-maintain bikes. Small to mid-sized two-stroke models were popular.

- End of production (late 1950s–1960s): Motorcycle production declined as competition grew, and Douglas largely stopped making motorcycles in this period.

- Common features: Simple, sturdy design; many two-stroke engines; various drive options (mostly chain drive, with some models offering other setups).

- Categories you’d typically find: commuter bikes, sport/road bikes, and sidecar motorcycles.
