1906 Advancements were made and soon all-chain drive was in use, with a
Dene two-speed counter-shaft gear working on the elliptical principle
and with a clutch.
1908 A two-speed hub gear was patented.
1910 The machines had become typical of the era and were now fitted with
Precision engines, belt
drive and sprung forks. There was a gradual move from a three-speed rear
hub to a two-speed gearbox. Singles and V-twins were built.
1914 A two-stroke was produced.
1915 There was some production that year but the war that would be over by Christmas wasn't, and manufacture came to a halt.
1922 One model was listed. It had an 8hp JAP
engine, three-speed Sturmey-Archer
gearbox and all-chain drive.
