[1] Although there were many makes of small runabouts of similar size and one to four cylinders at this time (before the Model T Ford dominated the low-price market), the Brush has many unusual design details showing the inventiveness of its creator.

The frame, axles, and wheels were made of oak, hickory or maple, and were either left plain or painted to match the trim.

Wider axles were available for use in the Southern region of the United States, where a 60-inch tread fit wagon ruts on country roads.

The engines were a single-cylinder, four-stroke water cooled design, producing 6BHP, with power going to a chain-driven rear axle.

Prior to the invention of the electric starter, crank-starting a clockwise-running engines frequently resulted in dislocated thumbs and broken forearms if the hand crank kicked back on starting.

The two boys convinced Jack to return to Oklahoma via automobile, and the trio purchased a 1910 Brush Runabout for the trip.
