The Debenham Sisters
Portland motorcycles were produced between 1910 and 1913 and again in 1920, and listed by dealers Maude's Motor Mart of Great Portland Street, London, and Halifax.
1910-1912 A machine was listed with a 4hp JAP engine, belt drive and Druid forks. There was also the option of a Peugeot engine.
1913 Still with belt drive, the machines now had 4hp JAP or 3½ hp and 4¼ hp Precision engines.
1920 They continued to sell their own brand of machine, built by a trade supplier, using components such as 269cc Arden two-stroke engine, Amac carburettor, two-speed Albion gearbox and Saxon forks. These lightweight machines were typical of the period, but a down-turn in trade saw them slip from the market.
