Overview
Wooler was a British manufacturer of motorcycles and automobiles established by engineer John Wooler in 1911 at Alperton, Middlesex. The company occupied an unusual position in the British motorcycle industry: rather than concentrating on conventional singles and twins, it repeatedly pursued distinctive mechanical arrangements intended to improve smoothness, balance, or packaging. One of its most recognizable styling and engineering characteristics was a petrol tank extending beyond the steering head, a feature retained across a number of Wooler machines. John Wooler had designed an experimental motorcycle by 1909. It used a two-stroke horizontal single-cylinder engine with a double-ended piston, reflecting his interest in unusual solutions to vibration and engine-layout problems. The first production design was a 230 cc two-stroke fitted with front and rear plunger suspension and a patented anti-vibratory frame. From 1912, Wilkinson manufactured the machine with a 344 cc engine and marketed it as the Wilkinson-Wooler. This arrangement gave Wooler an early route into production while retaining his design identity. Motorcycle production was interrupted during the First World War. The company entered receivership in 1915, but contracts for munitions supplied to the Royal Air Force helped it survive the wartime period. After the war, Wooler resumed motorcycle production with a more advanced design. A version was entered in the 1921 Junior Tourist Trophy, where its striking appearance led to the nickname “Flying Banana.” The company’s engineering experiments during the 1920s included fore-and-aft twin-cylinder motorcycles, a vertical-camshaft single, and other layouts that differed sharply from the industry norm. Wooler also attempted to enter the light automobile and cyclecar market. The Wooler Mule was announced in February 1919 and used a 1,022 cc air-cooled twin-cylinder engine with rotary valves. Its cylinders projected from the sides of the bonnet, while a circular dummy radiator provided a conventional visual cue despite the unconventional mechanical arrangement. A double rear wheel gave the vehicle the appearance of a three-wheeler. Only a small number of prototypes appear to have been built. The company was reorganized in 1920 as The Wooler Motor Cycle Company (1919) Ltd., after which Mule production ended. The reorganized business continued to develop motorcycles, but the economic conditions of the 1930s proved difficult. The Great Depression contributed to the company’s closure in 1930. Wooler later returned after the Second World War with another highly distinctive design: a 500 cc transverse four-cylinder shaft-drive prototype using a beam-type engine with cylinders arranged one above another. It was displayed at the Earls Court show in 1948 and again in 1951, but the engine did not operate reliably. In 1954, Wooler presented a substantially different transverse flat-four motorcycle, also air-cooled and shaft-driven. Post-war production remained extremely limited. No more than five examples of the transverse flat-four are thought to have been built, and motorcycle production ended in 1956 following John Wooler’s death. Wooler therefore remained a small, defunct specialist marque rather than becoming a mass-market manufacturer. Its historical significance rests on its inventive engineering, its willingness to experiment with engine architecture, and the survival of representative machines in motorcycle collections, including an example displayed at the British National Motorcycle Museum.
History
John Wooler designed his first motorcycle in 1909, before establishing the Wooler company in 1911. The early design was a two-stroke horizontal single-cylinder machine with a double-ended piston. The first production model displaced 230 cc and combined the engine with front and rear plunger suspension and a patented anti-vibratory frame. From 1912, Wilkinson produced a version with a 344 cc engine under the Wilkinson-Wooler name. The First World War interrupted motorcycle production. Wooler entered receivership in 1915, but military manufacturing work, including munitions contracts for the Royal Air Force, enabled the business to survive the war period. Production resumed in 1919 with a new motorcycle design. Its advanced appearance and unusual engineering attracted attention when a version competed in the 1921 Junior Tourist Trophy, where it was nicknamed the “Flying Banana.” Wooler’s interwar engineering program was characterized by repeated experimentation. The company developed motorcycles using fore-and-aft twin-cylinder arrangements, a vertical-camshaft single-cylinder engine, and other unconventional layouts. Most machines retained the long petrol tank that extended beyond the steering head, making Woolers visually distinctive as well as mechanically unusual. The company also pursued automobile-related production through the Wooler Mule cyclecar. Announced in February 1919, the Mule used a 1,022 cc air-cooled twin with rotary valves. Its cylinders projected through the sides of the bonnet, and a circular dummy radiator gave the vehicle a more conventional automobile appearance. A double rear wheel made it resemble a three-wheeler. Contemporary reports suggested a price that rose during 1919, but only a few prototypes were built. In 1920 the business was reorganized as The Wooler Motor Cycle Company (1919) Ltd., and Mule production ended. The reformed company continued with motorcycles during the 1920s. The onset of the Great Depression contributed to its closure in 1930. Wooler returned after the Second World War with a 500 cc transverse four-cylinder shaft-drive prototype. Its beam-type engine placed the cylinders one above another, a layout comparable in concept to the Brough Superior Golden Dream. The motorcycle appeared at the Earls Court show in 1948 and 1951, but it never ran properly. In 1954 Wooler introduced a different air-cooled transverse flat-four with shaft drive. Production was extremely limited, with no more than five examples thought to have been made. Motorcycle manufacturing ended in 1956 after John Wooler’s death. Surviving Wooler machines are now primarily of historical and collector interest; at least one example is displayed at the British National Motorcycle Museum.

Products and positioning
A British specialist engineering marque positioned around unconventional motorcycle design, experimental engine layouts, distinctive chassis solutions, and limited-volume innovation rather than mass production.
Motorcycle · 1911
Early Wooler two-stroke
Wooler’s first production motorcycle used a 230 cc two-stroke engine, front and rear plunger suspension, and a patented anti-vibratory frame. The design reflected John Wooler’s interest in controlling vibration through both engine configuration and chassis construction. A related 344 cc version was built by Wilkinson from 1912 and sold as the Wilkinson-Wooler.
Motorcycle · 1912
Wilkinson-Wooler
Manufactured by Wilkinson from 1912, the Wilkinson-Wooler was a 344 cc development of Wooler’s early horizontal two-stroke concept. It extended the company’s reach into production while preserving the unconventional engineering associated with John Wooler.
Motorcycle · 1919
Wooler Flying Banana
The “Flying Banana” was the nickname given to a Wooler motorcycle entered in the 1921 Junior Tourist Trophy. Its unusual appearance made it memorable in competition and exemplified Wooler’s preference for distinctive designs rather than conventional motorcycle layouts.
Cyclecar · 1919
Wooler Mule
The Wooler Mule was a small automobile announced in 1919. It used a 1,022 cc air-cooled twin-cylinder rotary-valve engine, with the cylinders projecting through the bonnet sides. A circular dummy radiator and double rear wheel gave it a distinctive appearance. Only a few prototypes were built before the company’s 1920 reorganization.
Experimental motorcycle · 1945
Wooler 500 cc transverse four
This post-war prototype used a 500 cc transverse four-cylinder shaft-drive powertrain and a beam-type engine with the cylinders arranged one above another. It was shown at Earls Court in 1948 and 1951, but the design did not run reliably and did not enter meaningful series production.
Experimental motorcycle · 1954
Wooler transverse flat-four
Presented in 1954, the later Wooler used a completely different air-cooled transverse flat-four engine with shaft drive. Production was extremely limited, with no more than five examples believed to have been built. It represents the company’s final major motorcycle engineering program.
