1923 A machine was built that was similar to many others of that era. It had a 247cc two-stroke Villiers engine, chain drive to a two-speed counter-shaft gearbox and then by belt to the rear wheel.
1924 A three-speed Sturmey-Archer gearbox was standardized, but the belt remained. A special competition model with all-chain drive, internal expanding brakes and a 54mph/86kmh speed potential could be obtained. Production stopped that year.
