Endurance were motorcycles produced from 1915 to 1925 by C. B. Harrison of Birmingham.
1915 A single model was listed, fitted with a 269cc Villiers engine. This basic machine had belt drive and petroil lubrication.
1919 After the end of World War I, the company's address was in Sheepcote Street, Birmingham, and they produced a machine with a 269cc Arden two-stroke engine, late in the year.
1920 A machine was produced that was fitted with their own 259cc two-stroke engine.
1921 They returned to using the 269cc Villiers unit. All models had the choice of single speed with belt drive or two speeds with chain-cum-belt.
1922 The range remained the same, but the 269cc Villiers adopted a flywheel magneto and pressure-fed oiling system.
1923 The range was doubled by adding 343cc Villiers-powered versions. This continued for the following year.
1925 Was the last year of production.
