Bennett & Barkell or B & B motorcycles were manufactured in Australia from about 1910 to at least 1917 by Bennett & Barkell Ltd. of 234 Pitt Street and later 124-132 Castlereagh Street, Sydney.
As was the case with most early Australian motorcycle companies, their machines were manufactured primarily from British parts. The B&B machines used JAP engines and Chater-Lea frames. They included 2.5 hp., 3.5 hp. 4 hp. (500cc), 6 hp. (770cc) and 8 hp. (1000cc) machines. Two piece tubular frame with engine as a stressed member. Used Druid forks and had large diameter (26 inch) wheels. Notable for a unique suspension system coupling the seat to the footboards (from ~1916).
In 1911 they asserted that the machine was built for Australian conditions with a key differentiating feature that they were "lighter in weight than the usual type of heavy-duty machine, but much heavier than the usual light-weight 90 or 100 lb. motor cycle". They further asserted that "the frame is scientifically constructed, too, and though lighter in weight than many higher-powered machines, will stand a greater road strain". This machine had a JAP engine of just 2.5 hp however "owing to the light construction of the frame it accomplishes as much as, if not more, than the cycles which are encumbered with a superfluous amount of metal".
From ~1916, B&B offered, as an option on the larger models, a patented suspension mechanism involving a sprung seat pillar; the "B. & B. Spring Frame Attachment".
In 1917, advertising promoted the combination of Australian Workmanship and English Material, together with success in the NSW Motor Cycle Club's Reliability Trial on 9 June 1917.
