From Dodge Wiki
The Rambler is an American bicycle brand manufactured by the Gormully & Jeffery Mfg. Co., in Chicago from 1878 to 1900. This bicycle brand was created by Thomas B. Jeffery and was the predecessor to Jeffery's Rambler (car).
The Rambler was still a proud piece of machinery when low prices took precedence over high quality. Its body featured flared metal tubing for extra strength at the joints, which were Brazing by immersion in molten brass. These techniques continued even after Gormully & Jeffery (G&J) and Rambler became names of the American Bicycle Company, or Bicycle Trust, which was not known for the best manufacturing techniques in all of its lines.
