Around 1900, the national bicycle craze turned to a newer invention: the automobile. In partnership with his friend Barney Oldfield, Fisher converted the bicycle shop to handle automobiles, telling his fellow racer, "I don't see why the automobile can't be made to do everything the bicycle has done."
Fisher promoted the automobile dealership as he had his bicycle shop with carefully planned stunts. He flew an automobile over Indianapolis supported by a hot air balloon, and pushed another off the roof of his four-story building in downtown Indianapolis.
Fisher made millions with the sale and manufacture of an early form of headlights, became involved with automobile racing and was a principal in the building of the Indianapolis Motor Speedway and the Lincoln Highway and Dixie Highway, two of the earliest paved roads across the United States.
