"The product of nine-years' research by New York State Museum curator Geoffrey N. Stein, The Motorcycle Industry in New York State is the first book to focus on the over one-hundred year history of motorcycle construction in the Empire State. Beginning with experimental motorized bicycles in the 1890s, New York's motorcycle industry experienced its golden years for innovation and production in the 1900s and 1910s. The essays in this work mark both that promising start and the decline of the motorcycle industry, when the public adopted automobiles for everyday transportation. But here, too, are reports of a construction renaissance, as small shops from Long Island to Grand Island produce custom motorcycles in small numbers."
