In the United States, the "California Motor Company" was formed in 1901 to sell complete gasoline-engine motorbikes in San Francisco, Oakland, and San Jose. The company began with a 200 cc single-cylinder, 1.5-horsepower, four-stroke engine designed by R.C. Marks. Mounted to a standard bicycle frame, the "California" could reach speeds of approximately 25 mph (40 km/h). The "California" weighed around 75-80 pounds, and featured a leading-link front fork, a leather spring saddle, a front "Duck" roller brake, and an "Atherton" rear coaster brake. A leathern belt-drive directly connected the engine output shaft to the rear wheel. During the summer of 1903, George A. Wyman rode a 200 cc, 1.5-horsepower "California" from San Francisco to New York City, becoming the first person to cross the North American continent aboard a motor vehicle.
