From “Velodrome Racing and
the Rise of the Motorcycle” —
“On March 30, 1894, page one of the Evening Democrat out of Warren, Pennsylvania, included a brief item intended to be of interest to cyclists and cycling.
The new wrinkle in bicycles is called the “Motor Cycles” and is manufactured in Cleveland, O. The machine is driven by means of an oil motor weighing 10 pounds which is attached to the frame back of the rear wheel. One gallon of coal oil will drive it 200 miles. The wheels are provided with pneumatic tires four inches in diameter.
And so was launched the legacy of the first petrol two-wheeled motorcycle in America along with that of Edward Joel Pennington, one of the most improbable characters in the history of motorized transportation.”
Earliest commercial use of the term “motor cycle.”
