Moore-Car

In 1917, the American company W. G. Moore of Indianapolis introduced the lightweight, single-seat Moore-Car on a motorcycle-type chassis with automotive components.

It pioneered the classic layout and appearance of future two-wheeled vehicles. The car used a water-cooled engine with an automobile radiator, a three-speed transmission, a tubular frame, and rear-wheel drive on a leaf-spring suspension. Its features were a peculiar half-rudder, two track rollers on longitudinal levers with a push-button locking device, a rear “shaped” gas tank and wide side steps.

The peak of interest in monocars was in the third decade of the twentieth century, when they began to be designed and manufactured by both unknown firms and large armaments and aviation corporations.
