The Sears Roebuck and Company was responsible for some of the most outrageous and sought after bicycle designs. The Elgin Bluebird, Robin, Blackhawk, Flightlinger and Spaceliner were all Sears exclusives. Sears primarily used the Westfield Mfg. Co. and Murray of Ohio to produce their special bicycles designs. Sears bicycles sold before World War II were branded as Elgin, and after World War II as J.C. Higgins.

The Elgin Twin Bar bicycles were produced by both Westfield and Murray Ohio. The unique perimeter frame omitted the traditional seat tube by using a sliding bracket to hold the seat post. The Twin 20 was the entry level Twin Bar model and there was also a Twin 40, 50, and 60 which featured a battery pod, a
headlight built into the head shroud, built in speedometer and aluminum fenders and chainguard. Formerly owned by Shawn Sweeney
