The 1904 Knox was a runabout model. The angle iron-framed car weighed 1850 lb (839 kg) and used side springs. It could seat 2 passengers.
3 or 4 wheels
Initially, only three-wheelers were offered. Four-wheeled runabouts soon followed.
Back seat driver
In some models, passengers rode up front over the front axle while the driver and another passenger sat in the back over the engine.
The "Old Porcupine" engine
The flat-mounted air-cooled single-cylinder engine (which led to it sometimes being referred to as "Old Porcupine", due to the numerous projections on the cylinder cases) was situated at the center of the car and produced 8 hp (6 kW). This engine was also called a "hedgehog". A 2-speed planetary transmission was fitted.
The "Knoxmobile" sold for US$1350. By contrast, the Ford Model F was US$2000, the FAL US$1750, the Cole 30US$1500 and Colt Runabout each US$1500, the Oakland 40 US$1600, and the Enger 40 US$2000, while the high-volume Oldsmobile Runabout ran US$650, Western's Gale Model A US$500 and the Brush Runabout was US$485.
A larger Knox tonneau model, equipped with a straight-2 engine producing 16 hp (11.9 kW), was also produced, for US$2000.
The Knox was raced by Billy Bourque in the 1909 AAA Championship Car race at the Indianapolis Motor Speedway.
