Tractor-Cycle, Treaded Motorcycle Designed by French Inventor J. Lehaitre, ca. 1938

In 1938, inventor J. Lehaitre introduced a fascinating innovation known as the Tractor-Cycle—a motorcycle equipped with a tractor-style transmission belt instead of conventional wheels. Designed to handle a wide range of terrain, this unique vehicle could travel at speeds of up to 25 mph.

Its rugged, tank-like track system gave it impressive off-road capabilities, making it suitable for military or rugged exploration purposes. In fact, it was even designed to accommodate a machine gun, suggesting potential military applications at the time.

Though it never became mainstream, the Tractor-Cycle remains an intriguing example of early 20th-century experimentation in all-terrain vehicle design.
