"George Wyman’s machine, a 1902 California Motorcycle Company “motor-bicycle,” had a 200cc, 1.5 horsepower, four-stroke engine bolted to a standard steel bicycle frame. Wyman’s machine was equipped with 28” x 1.5” pneumatic tires on wooden rims, a leading-link front suspension fork, a springed seat, a Duck Brake Company front roller brake & an Atherton rear coaster brake. A leather drive-belt with a spring-loaded idler pulley directly connected the engine output shaft to the rear wheel. The California weighed roughly 80 pounds & was capable of a top speed of approximately 25 miles per hour.
☞In order to save weight, Wyman packed only one change of clothing, a water bottle, various small tools, one can for spare oil, one can for reserve gasoline, a Kodak Vest-Pocket camera, a cyclometer, & a .38-calibre Smith & Wesson revolver."
