Humber Motorcycles Timeline

Humber produced motorcycles from 1896 to 1905, and from 1909 to 1930.

1884 Made the first diamond-frame.

1896 The company started experimenting with powered machines, working with entrepreneur Harry Lawson, who had the rights to build the De Dion engine, in Coventry.

1896 At the 1896 International Horseless Carriage Exhibition Humber showed 'motor cycles fitted with the Kane Pennington motors and two tandem safeties with the twin-cylinder motors boomed out at the rear'.

1896 'The first practical motorcycle built in this country was completed last week when Humber and Co finished a bicycle fitted with a Pennington two-horsepower motor made at their works in Coventry'.

Also in 1896, Humber established a subsidiary in Sweden, Scania, which built their first motorcycles in 1902 and eventually became the vast Scania-Saab corporation.

1898 Lawson also had the rights to De Dion's tricycle, which Humber made for them.

1898 The company first constructed a power tandem, driven by a battery powered electric motor. Although its life was short, it proved to be useful on racing tracks where it was used for cycle pacing. A ladies' bicycle, modified to carry an engine behind the seat tube, was also produced, along with a forecar known as the Olympia Tandem. This was based on the Pennington design, with the engine hung behind the rear wheel.

1902 Humber became a serious contender in the field of powered transport and two models were produced. Both were very successful and proved their worthiness at shows and in trials. The smaller used a 1½ h.p. engine hung from the down-tube with belt drive, the larger 2 h.p. model was made under licence from Phelon and Moore, so had the engine fitted as the frame downtube. From there it drove the rear wheel by chain in two stages. These were raced in competition by the work's riders J. F. Crundall and Bert Yates.

Report from the 1902 Stanley Show

Stand 125. Humber, Ltd., Beeston and Coventry. Seven motor-bicycles are shown, all of the Standard Humber chain-driven type.

A resuscitated Olympia tandem is on view, with 3 h.p. engine, chain-driven, spring seat-pillar, and a luxuriously upholstered wicker seat between the front wheels, in which a passenger (lady preferred) can be carried. Wipe contact is employed on all Humber motorcycles, the trembler being on the coil.

The Humber chain-drive is perhaps too well-known to need further description, but we might just remind novices that the engine is hung on four pillars which replace the usual tube from head to bracket: the drive is taken by chain No. 1 from engine cog wheel to large chain wheel on bottom bracket spindle; inside this chain wheel is a smaller one, also fitted on the spindle, but running on a free-wheel clutch; from this chain wheel chain No. 2 runs to the back wheel hub. On the other side of the machine is chain No. 3, which is used solely for starting purposes; chains Nos. 3 and 2 are interchangeable as to length, so that any undue stretch in chain No. 2 is counteracted by swapping chains.

Free engine is obtained, so that the engine can be idle when the machine is running downhill, and so get an additional chance of cooling. Ample brake and mudguard accommodation is provided on all Humber motorcycles. The same disposition of engine, chain-drive, etc., is employed on the Humber motor-tricycle, the engine being situated within the wheel base, and the weight carefully distributed. Prices are as follow: Motor-bicycles, Coventry-made, 1.75 h.p., £50; 2.75 h.p., £55; Beeston-made, 1.75 h.p., £60; 2.75 h.p., £65. Tricycles, Coventry-made, £65; Beeston made, 75 guineas.

Motor Cycling, 26th November 1902

1903 The success of the two previous models led on to the development of new machines. All had chain drive and comprised 1¾-hp and 2.75-hp solos, a 2¾-hp tricar with single front-wheel, and the Olympia Tandem forecar. All were listed in two forms, the 'Beeston' or the cheaper 'Coventry', as was Humber's bicycle practice.

1904 The tricycle was dropped, the smaller model became 2-hp and the Olympia was fitted with a 3½ hp water-cooled engine.

Humber 1903-1904

1905 By now most efforts were going into the production of Humber cars, so motorcycles were temporarily dropped.

1909 The name returned with the with just one 3½-hp model of conventional form with belt drive and the option of a two-speed rear hub. An unusual addition was a silencer that formed part of the frame downtube, and sprung front-forks with blades that pivoted on a bearing in the lower crown against springs. See Humber 1909-1919

1910 Normal silencers and Druid forks made a return, the firm added a new 2-hp model in both lightweight and ladies' variations and also entered the TT.

Stanley Show 1910
Humber, Ltd. Coventry.
Stand No. 53.

The 3.5 H.P. two-speed Humber will undoubtedly prove a very great attraction on this stand. The frame is a new design, exceptionally strong, being only 281in. from the ground. The machine has a long wheelbase and improved pattern spring forks. The engine is a 3.5 H.P. 83 mm. by 90 mm. bore and stroke, with ball bearings to the main shaft, and large mechanically-operated valves. The front rim brake is exceedingly well made, and a powerful metal to-metal band brake is fixed to the back hub, and operated by the foot pedals. The carburetter control is by Bowden wire from the handle-bar; ignition is by high-tension magneto, gear driven transmission is through a variable pulley by best-quality rubber V shape gin. belt, the variable pulley giving 4 to 1 and 51 to 1 gears. The free engine clutch and two-speed gear is made under Roc patents, and the rest of the specification is carried out with that thoroughness with which the name of Humber is synonymous.

We recently referred to the new 2 H.P. light-weight motorcycle, which the company are now placing on the market. This machine weighs only 90 lbs., and is a beautifully- finished article. The engine is 2 H.P., 60 by 70 mm.; the ignition is by Bosch high-tension magneto, gear driven. The entire control, including exhaust valve lifter, is operated from the handle-bar without lifting the hands from the grips. The wheels are 26in. by gin., Dunlop motor-cycle, beaded edge, special rubber-studded tyres being used. The transmission is by belt of best quality, the pulley being variable, and giving 5 to 1 and 8 to 1 gears. The price of £37 is very reasonable for a machine of such very high quality, and we anticipate that the Humber light-weight will speedily become one of the most popular bicycles on the road.

1911 Humber produced a striking new 2¾ h.p. V-twin model of 339cc. The engine was unusual in having a master connecting-rod to which the second rod hinged. The Bosch magneto was gear driven and clamped to the rear of the crankcase, the carburettor B and B, and Druid forks used. It performed particularly well on its debut at the TT - with all six entries finishing and a win.

1912 Spennell's lists them at Humber Road, Coventry (Tel. 522). The 3.5hp model was revised and a 2¾hp V-twin introduced, while the 2hp machine ran on as well.

1913 An unusual design appeared with a horizontally opposed three-cylinder engine - one 373cc cylinder faced forward and the other two of 185cc cylinders, with a common combustion chamber, faced aft. The crankcase was formed to take the two rear-rods either side of the front one, there was a large external flywheel and the magneto sat on top of the crankcase. This very strange engine drove a car-type three-speed gearbox by chain with chain final-drive. Only one small batch of this model was ever produced.

WWI During World War One they made sidecar outfits for the war effort.

1914 All continued much the same for the next couple of years, with the addition of a water-cooled version of the 3½-hp model, intended for sidecar work.

1915 Only the 3.5-hp single remained in production and the 3-hp was replaced by a conventional 6-hp water-cooled flat-twin driving a three-speed gearbox with chain final-drive.

1916 Only flat-twins were built, with the 6-hp model joined by an air-cooled 3.5-hp model, also with three speeds and chain drive. Few of these machines were produced.

Post World War I. The 6-hp twin was dropped, while the 3.5-hp flat-twin was first joined and then replaced by a 4.5-hp version of 601cc. Various other models were produced, modified or dropped, including a sports model, a 349cc sv single, an ohv model, and a neat ohc version with shaft and bevel drive, rear magneto and the oil pump driven from the camshaft end. This trend continued until the end of the 1920s.

1923 In came a 2¾ h.p. lightweight sports model powered by a single cylinder side valve engine of 349cc. Refined and speedy, the newcomer proved good enough to secure Humber the Team Prize in the ACU (Auto-Cycle Union) Six Days Trial, and would remain in production until Humber ceased motorcycle manufacture.

In 1927 they announced a 350cc ohc machine, but it was not successful.

1931 Sales slumped and the company had left motorcycling to concentrate on cars. Their bicycle business was sold to Raleigh.
