In 1906 manufacturers considered their bikes superior because they didn't employ women:
MALE OR FEMALE LABOUR.
The male mechanic in the Workshop has proved himself infinitely superior to the female - he is capable of doing better, more exact, more reliable work.
Morally, mixed labour does not raise the standard of either worker, and considerably lowers the standard of the work produced.
TRIUMPH Cycles are made in a factory where no female labour whatever is employed. Female labour and best work do not go together therefore let your machine be a TRIUMPH. "The Best Bicycle British Workmanship can produce" and made by skilled male mechanics only.
The TRIUMPH is the only Coventry Cycle Factory not employing female labour.

We may not yet have reached equal pay, but there's been a bit of progress!
