1913 A V-twin was added, along with Fafnir singles.
1916 The range had been cut to two models. One used the 2½ hp JAP engine and the other a 2.75.hp Peco. Both had two speeds, chain drive and sprung forks. The war intesified, and motorcycle production ceased.
1920 The marque reappeared with two models. One had a 293cc JAP engine, two-speed Burman gearbox and chain-cum-belt drive. The other had a 293cc Union two-stroke engine and Enfield two-speed all-chain transmission. Both still used the patent spring frame.
1922 The two models from the previous year were now fitted with 545cc Blackburne and 348cc sleeve-valve Barr and Stroud engines. The larger was only built for that year.
1923 Other models continued and there was also the 348cc Blackburne. During that year the company suffered financial collapse, but it was quickly reformed to carry on using the same JAP, Blackburne and Barr and Stroud engines. They continued in this vein for the next few years.
1926 By that year only the 348cc sv and ohv Blackburne engines were utilised. It was to be their last year.
A few days ago we were able to test the Douglas-engined spring frame Edmund illustrated in The Motor Cycle of July 9th. The combination of the smooth running horizontally-opposed engine in conjunction with the clever frame design rendered the machine one of the most comfortable we have ever ridden. The machine was driven at a smart pace over a very bumpy stretch of road, but the leaf springs and coil shock absorbers reduced even the worst bumps to such a degree that no jar of any sort was felt, but only an easy undulating motion.

Edmund machines are, of course, famous as pioneers in the movement to provide increased comfort for the rider. The forced alteration of the oil filler to a more convenient pattern. The weight of the three-speed model is still well under 180 lb., the two-speed model being proportionately lighter The sports model is fitted with a close ratio gear box. The engine of the latest machine is a development of the 1922 type of racing unit.
The machines have been manufactured substantially in their present form for many years past. For 1923 three models are offered, namely, touring, sports, and super-sports, all of which are normally fitted with Blackburne engines overhead valves being utilised on the super-sports type.
Options consist of a Barr & Stroud engine on the touring model, or a special J.A.P. engine on the sports model. The policy of the firm is to offer 350 c.c. machines of the best quality, distinguished by the comfort bestowed by the patent frame. Several minor alterations of interest are to be noticed. The cast aluminium chain guards are exceptionally neat. Customers may choose either a sprung or rigid carrier.
A large armoured toolbag is fitted to the tourist model. The sports model carries its expansion box in the modern fashionable position level with the rear wheel ; this box is of excellent pattern, being of rectangular shape made in cast aluminium and very heavily ribbed in order to cool the gasses as far as possible.
