By 1914 they were producing 10,000 bicycles per year
WWI They made armaments, particularly artillery shells
1921 The company produced around 20,000 cycles.
1923/4 A third move was made to an ex-Dunlop factory in Aston. This became known as 'Britannia Works', and grew until it occupied thirteen acres, and was the site of the company's
1927 Hercules made 250,000 cycles
1929 Six years later another Dunlop works was acquired, this time less
than a mile to the north-west in Long Acre, Nechells, Birmingham. This
second site was named 'Manor Mills'
During this period, Birmingham had been home to a very large number of
cycle manufacturers, most of which did not prosper. The success of Hercules
was attributed to a number of factors, including the name. The production
methods used by the company (after 1923, Hercules produced the majority
of the components of their bicycles, apart from the inner tubes and tyres)
on site. The factories were run using principles of mass-production, allowing
the production of over a thousand cycles per day (each taking less than
10 minutes from start-to-finish to assemble).
Hercules also exported a significant percentage of their production - by
the time Sir Malcolm Campbell was invited to see the three millionth bicycle
completed in 1933, over half the production had been sold sent overseas,
earning the country £6 million and letters of congratulation from
the King and Prince of Wales.
Production continued apace, and by the end of the thirties, Hercules had
produced over six million bicycles, and could claim to be the biggest manufacturer
of cycles in the world.
A third factory was added in the 1950s in Plume Street, Long Acre, a short
distance from Manor Mills. By this time, Hercules had became one of the
largest businesses in Aston, and was said to have helped to give the area
much of its character.
In 1946 Sir Edward Crane sold Hercules to Tube Investments for £3.35 million. TI had been the main
supplier to Hercules, providing the company with the tubing from which the bicycle frames were made. They combined the company with the Norman, Phillips and Sun brands to form the new British Cycle
In 1952 Eileen Sheridan became involved with Hercules. Eileen broke a large
number of records riding for Hercules between 1952 and 1954.
1956 Tube Investments were forced to make 1,250 employees of the British Cycle Corporation redundant,
following deadlock with the unions, who refused to reform working practices. Many of the workers were from Hercules factories
1956 The firm produced a moped fitted with a 49cc JAP engine, which, to begin with, sold as the Grey Wolf. Soon this name was changed to Her-cu-motor. The two-speed
gearbox and bevel box with chain final-drive had an engine with the crankshaft set along the machine. The unit hung from a spine frame with leading-link front forks. The overall
effect was quite sleek.
1958 Production of the moped came to a close when supplies of the JAP
engine dried up.
1958 Tube Investments bought the Nottingham-based Raleigh Cycle Company in 1958 to form TI Raleigh
Industries. Combined, they controlled 80% of the British bicycle market.
1960 A new moped model was introduced. Fitted with a 49cc French Lavalette engine in a simple, rigid frame with telescopic forks, it was known as
1961 Moped production came to an end.
1961 Manufacturers of Hercules cycles.
Management of the British Cycle Corporation was handed to the Raleigh management,
as that company with its greater domestic focus, was now the larger and
better known. Raleigh quickly decided to cut the number of brands, and
move to using Raleigh designs and standards.
Production was concentrated in Nottingham in 1960, and by 1963 there was little left of a distinctive Hercules.
2003 The original company - still part of Raleigh - was eventually dissolved on 2 December 2003
