They decided to go into full manufacturing, but their fathers thought the automobile was an "instrument of the devil" and so sent the two young men back to studying at college.

After graduating from college, his father gave him money for a service shop in Germantown so he would stop making cars.

[1] Carl Kelsey designed an automobile that would be less expensive than the Model T. Introduced in September 1910, the three-wheel vehicle was the Motorette, built in Hartford, Connecticut.

The Motorette (a name that he trademarked),[1] was rear-wheel driven by a two-stroke, twin-cylinder engine which was air-cooled on early models.

[2][1] With a 74-inch wheelbase, it weighed 700 pounds and was advertised with the slogan "No roads too rough, no hills too high."

After the car overheated and Kelsey had to spend the night in a halfway house, he changed to a water-cooled engine.

[1] Some engines built by Lycoming factory workers were sabotaged, and this caused Kelsey financial issues.
