In 1921, German entrepreneur Carl F.W. Borgward (1890-1963) established the Bremer Kuhlerfabrik Borgward & Co., an automotive radiator company in Bremen, Germany. He also designed a two-horsepower, three-wheeled courier motorcycle called the Blitzkarren ("lightning cart"), and later the Goliath three-wheeler which, by 1925, was used by the German postal service for mail deliveries.
