L.D.E. Motorcycles

Frank Desborough ran an engineering business in Commercial Road. In 1951 he built a machine to compete in the Isle of Man T.T. races. It was powered by a 125c.c. engine, and had disc brakes. 

Juckes

Juckes motorcycles were built by the Efficient Engineering Company, which was set up by T. C. Juckes.  The Efficient Engineering Company specialised in gearboxes, engines and electric lighting sets. The company was based in the East End Works in Bilston Road Wolverhampton. Mr. Juckes built his first motorcycle in 1902. Juckes built several motorcycles in 1907 using ACME V-twin engines and chain drive. In 1912 the company produced a 4hp water-cooled motorcycle engine, and a 4-speed gearbox for motorcycles. In 1913 and 1914 the Juckes 4-stroke, 4¼hp. big single engines (with overhead or side valves) were used by several leading motorcycle manufacturers.

In the early 1920s T. C. Juckes decided to produce a range of 2-stroke motorcycles at the works, all built to his own design. Many of the main components were also designed and built in house, including the engines, gearboxes, frames, petrol tanks etc. The engines were of an improved 3-port design, which used the Juckes patent double transfer passage and oiling system. In 1925 Juckes launched three high performance machines, the ‘G’, ‘G4’, and ‘GA’. The machines were powered by a Juckes 4-stroke, 347c.c. O.H.V. engine, with a 3 or 4-speed gearbox, mechanical and hand pump lubrication. Unfortunately in the latter half of 1925 the company found itself in deep financial difficulties, and was declared bankrupt. At the time of closure only 9 ‘GA’s had been built. The two-stroke machines sold quite well, around 683 were built. The company’s best year was 1923, when over 400 machines were produced.

JP – the Impregnable Motorcycle

JP were the initials of John Piggott of Cheapside, London, who produced a motorcycle early in 1913.

This machine had a 2.75hp engine, belt drive and sprung forks. There was also the option of a hub gear.

The  JP, the “Impregnable Motorcycle” was displayed and listed until the middle of 1914, the outbreak of World War I stopped production.

Rova-Kent

I just came across a 1913 report on the Rova-Kent which I know is in your A-Z but as its Australian I thought you might like the attached pic. The original caption read:  “CWA Korner on his 3½hp Rova-Kent motor cycle, which was built and designed by Messrs Eglinglon and Clarke, of Adelaide. He made fastest time of the day in a hlll-climb organised by the South Australian MCC. Note the engine, which has two inlet valves and two exhaust valves ot the overhead type, and a ported cylinder. The crank case is of gunmetal; a Bosch magneto and B&B carburetter are also fitted.”

Craven

I just found a story in The Motor Cycle’s Olympia Show preview, 1913:

“The Craven Motor Co., 116, Greenwood Road, Dalston Lane, N.E., market
a  sidecar combination possessing’ several novel features, the chief being the manner in which the rear wheel of the 9 h.p. J.A.P.-engined machine is sprung on leaf springs. This naturally gives great resiliency, and the wheel cannot shift, as it is in a rigid frame, the springs being placed above the rigid forks and the rider’s weight corning on another frame which is placed on the springs. The sidecar is also sprung on similar type springs, to the ends of which the body is secured by bolts passing through the floor. On the roughest roads little shock can reach the driver.”

There’s a pic of a two-seat Craven wickerwork sidecar later the same year but nothing the following year so it looks like it didn’t get into full production. Judging by the pic that might be a good thing.

AB – Lindblad

Motorized Drott bicycle made by Lindblad in Stokholm in early 1920s.

Velociped AB Lindblad was a Swedish bicycle manufacturer and distributor. They built their own bicycles of the brands Blixt and Radix, and they sold bicycles of the brands Crescent and Drott as well as bicycle accessories. They also imported AJS and Harley-Davidson cars and motorcycles. The company was founded in 1896.

 

A.V.

A.V. – 1903 – 2 hp

The A.V. Motor Co. was based in Aston Lower Grounds, Witton, Birmingham.
They were manufacturers of cycle motors and accessories. T he gentlemen in charge were J.G. Accles and F.H. de Veulle, hence the name A.V. De Veulle’s name was mentioned regularly in early Motor Trader magazines in relation to patents for carburettors. The firm presented its first machine, built up with BSA fittings, at the Stanley Show in London in November 1902. Bore and stroke of the engine were 2 9/16 inch x 3 inch. In the 1903 catalogue the company proudly declared: “ We have overcome leaky crank case troubles, lubricating troubles and contact breaker troubles.“ An unusual feature of the engine was the way the cylinder and crankcase were held together: “ The cylinder has a projection at the lower end which fits into a recess in the upper end of the crank case. A large ring nut is screwed on the cylinder and firmly binds the cylinder and crank case together.” Even more unusual was that the petrol tank, oil tank, carburetor, tool box and battery were all housed in a highly finished wood case. The customer could choose between oak, walnut and mahogany. 

The carburetor was of the F.N. type.

Ireland

Ireland, 1912, made by Ireland’s Garage, Cleveland Road, Wolverhampton, West Midlands. The Motor Cycle mentions a 450cc single and two twins of 584 and 634cc, Blumfield engines.

Woodrow-JAP

The Woodrow was a British cyclecar and motorcycle manufacturer based in Stockport from 1912 to 1915.

Woodrow primarily made cyclecars. The 1913 cars were powered by a choice of water or air-cooled V twin engine of 964 cc made by JAP, with a three-speed gearbox and chain drive to a back axle that was unusually, for cyclecars of the time, fitted with a differential).

In 1914 or possibly 1915 the engine was replaced by a larger V twin, water-cooled only, of 1090 cc from the Precision Motor Cycle company.

Thanks to Dave Richmond for the motorcycle picture.

CAECO

There are three mentions of a Caeco (made by Cambridge Automobile And Engineering Co) in the 1912 Motor Cycle, with 482cc 3½hp and 340cc 2¾ hp ohv JAP engines which competed in a race at Brooklands and a club hillclimb.

“A new machine, the 2¾ Caeco, ridden by H. P. Storey, made its debut in this class [350cc]. Unfortunately, it appeared to be suffering from over-lubrication, but, though misfiring badly, it made quite a fast ascent. The engine was a 2¾ overhead valve J.A.P., and was mounted in a racing frame just big enough to surround it. It had no exhaust pipe, and was fitted with a Longuemare carburetter. Its appearance was striking—so was its exhaust.”
