Huskvarna 1903 -

Husqvarna 1000 cc, almost identical to an Indian or HD, technically from the 30th. The company started to sell bicycles and later they put in a small engine. Already 1920 they had their own 550 motor and later a 1000cc. With this they went into competitions.

It was a success mostly due to the brilliant designer Folke Mannerstedt. Huskvarna won several World Championships. During the 30th they brought in line with what people wanted. Cheap 2-stroke bikes were sold. With successful models of these types Huskvarna managed till end of 50th.

With the help of world known drivers like Bill Nilsson, Håkan Carlqvist and Torsten Hallman Huskvarna became a Cross machine with a high reputation. The bad luck for Huskvarna was that they had an extremely wide production program and among these product they had freezers.

Husqvarna had to invest overflow money. But it was not enough. Therefor Husqvarna was bought by Electrolux. Product that didn't suit Elecctrolux were sold. The motorcycle part was bought by Cagiva in Italy 1986.

Sorry to say all these kind of fusions are leading to that the maretk disappears some time later. In this case Huskvarna, as a company, ended all production and lots of good engineers and workers went out of job. The end result of the fusion with Electrolux, became only a short time higher book-keeping finances for Electrolux.

After some time Huskvarna only produced freezers and alike. The best ad at that time was "Do as Electrolux buy Huskvarna". Several of the designers and drivers started their own production. Husaberg! They had difficulties with money and had big problems to economically fight the Japanese dragoons.

Today in the honorable workshops of Huskvarna city there is only a very nice museum. Pity, Sweden might have had a mc producer with a high standard.

Motorcycle, home built.

Engine and cycle frame was produced 1915 by Sigurd Carle, Marnäs Ludvika. Carle constructed also the headlight and carburettor. This was copied after a foreign model like "Schebler model H Bosch". The headlight had it's own carbid gas unit. This mc was the second that Carle built. For this mc he bought wheels and frame from other established manufacturer.

Technical data.

Two cylinder two stroke side valve? engine 225 cc.
Power ca 4 ps
Two gears and friction coupling.
Length 2,2 meter
Width 0,84 meter
Height 1,03 meter

Note 1: Transcript from museum info.
Note 2: Wonder if how a two stroke side valve engine look like?. May be the info means a engine with two inlets.


During 1920 it was not unusual that handy people built their own motorcycles. Normally there were students studying for technician or engineer. They could not afford a factory made cycle.

During the engineer education Carle went to Technical School in Örebro. During this time he made the wood parts for casting, the engine details for his own constructed engine.

Note. Gustaf Larsson and Sven Winquist at Volvo also studied in Örebro Technical Elementar School. Gustaf got also experience in England. It might be very remarkable that these highly educated persons not emigrated to America. Compare with the Hult brothers, Ljungström and all those who came back to build Volvo company.

The Carle's motorcycle got the register no W1 and is a good example for private made cycles at this time.

The cycle was given away 1967 to Technical museum in Stockholm by Arne Carle in Malmö. Now on show in Åssa museum.
Compare with the Park mc from Västerås. See MC-museum Surahammar.

Ariel 1930 500 cc 1 cylinder.
Owner: K-G Salomonsson.

Ariel 1902-1970

One of the most successful marks in England. In the beginning of the mc history the development went ahead like stepping in stairs.

For Ariel it started with bicycles 1870. At that time James Starley invented the wire spoke wheel. This was a necessary invention for motorcycle progress. Benz used it on his first 3 wheeler 1886.

Next step was the invention of rubber tire which hadn't went applicability until 1898 by John Boyd Dunlop. His patent was not valid because Robert William Thomson had en earlier patent.

It can be mentioned that several different trials were made with other types of elastic wheel covers by the aircraft manufacturer Fokker. He made this in his youth in the Netherland.The construction used inbuilt springs in the rims. The standard car of his father was used. See the book by Antony Fokker The Flying Dutchman.

The wire spoke wheel was produced by Starley's company, which later became Ariel. Their first motor bicycle came 1901 as a three wheeler with DeDion engine. Ariel went of course bankruptcy as all other firms, but was saved by Charles Sangster.

He got Ariel on feet again with a 2 stroke motor, 3 geared box and kick start. Charles son Jack took over and continued with Jap engines until a famous designer named Val Page was employed.

He brought with him a concept for a four cylinder engine which was called Square four. This type was kept together with twins as far as to the end of 1970 when discontinuing was inevitable in spite of a possibly contract for the English defense.

Ariel got constructions from BSA who had taken it as war booty. With these Ariel made their models Arrow and Leader.

Dunelt 1930

Dunford & Elliot, was an old company in Sheffield. It was dealing with steel production.

1919 the company bought motorcycle knowledge. This had a high reputation at this time in England. Dunford & Elliot started to build motorcycles in Birmingham.

The shown Dunelt with 500 cc was bought 1931 by one in Åtvidaberg. As we know, this mc has not been driven since early 1950. The cycle is mechanical untouched and is nice working. It has original tires, saddle and bags. Only the mufflers are new and produced at Facit.

Dunelt 1919 - 1956.

Dunelt made trials with several different engine constructions. The most remarkable one was for their two stroke engine when they tried double cylinders.

Later they tried Villers sv and ohv engines with volumes up to 498 cc. These were made by Rudge or JAP.  The production ceased 1935 and started again 1956 with a 49 cc moped and with an own ohv engine. It didn't became popular.
460 Dunelt have been registered in Sweden and of them 46 are still left.

Honda 1849 -

Soichiro Honda, 1906-1991. He worked at home in his father's garage for bicycles and motorcycles. He realized, after the WWII, that people needed transportation vehicles and bought one stock of surplus mc engines.

With these he built his first mc 1947 and called it Type A. (Bugatti called his first car for Type 1). 1948 he formed Honda Motor Company.

When he got his partner Fujisawa, who also had the knowledge how to handle finances, they succeeded to roll the company through the difficult years after the war.

In the middle of the 1950th the company started to grow and late 1959 they had a good grip of the market. He realized that big selling was due to success on the competition tracks and he made that.

1958 he put out an enormous seller, a moped with 50 cc engine. Just what Asia needed. 100000 was manufactured a month!! 1968 the CB750 four was announced. This was a mc with several new things like electric starter and disk brakes.

Now Honda was controlling the market and produced one after the other several hits. Very much depending of that he never let a bad construction leave the works. He never got a bad reputation.

The Honda 750 four in Surahammar MC museum is a motorcycle that made the world astonished and did completely outclass the English mc industry.

BSA 1903-1990

Birmingham Small Arms produced  10000 rifles a week and 145000 machine guns before WWI.

This was the result that William III in the end of 1600 century understood that he needed a war industry independent of foreign countries.

Already 1903 the first bike was built, although it had Belgian Minerva engines. These bikes were green which became the BSA color. Till WWII several different models were sold with increasing volumes.

Names as Sloper, Blue Star and the M-Range. The last well known for it's use by AAA as support bike on the English roads.

 During WWII they delivered lots of model M20 for the defense.


BSA took as war booty over the MC design apartment from Adler but didn't used the information. Instead Ariel got it in their hands.

After the war BSA started with a cheap machine and sold ca 500000 till 1963. This was a copy of the DKW 2-stroke bike converted to inch and mirrored.

Well known are all A-models like A10, A65, Gold Star, Rocket, Spitfire and so on. The declining production from BSA forced action together with Triumph and Norton. This turned out to be a failure when the employers wanted to decide themselves.

Four years later all were fired and a national company NVT started to produce spare parts for these English bikes. Some new production were aimed but with foreign engines in the end of 1990.

Corgi/Excelsior Welbike about 1944. Ref 1

Excelsior Welbike.

The English army used a type of motorcycle during the WWII which they dropped from aircraft by parachute. The cycle was primary meant to be used for invasions.

During WWII 3853 cycles were produced for the army from this model by the Exelsior factory in England.

When the war was over another company (Brockhouse Corgi) took over the production and 1946 they introduced a mini scooter for the civil market. This is the model shown at the museum.
Transcription from museum info.

Corgi Welbike 1946. Ref 1
The picture shows the case for dropping the mc by parachute.

Welbike history.

The idée for this small mc was given by Colonel John Dolphin who worked in the development department.

In Southport just north London the English defense built a development factory to produce special vehicles. They were meant to be used in the WWII. Among all those vehicles was one to be used by the airborne troops.

All that were developed in this place Welwyn got names which started with "WEL". In this case Welbike.

Corgi Welbike at Falköpings museum. OBS modern engine. Ref 1
Modernized Well-Bike at falkoping c museum

The first trial was a simple engine driven bike from Excelsior with 98 cc engine. without starter, light and brake only on the rear wheel. It was meant to find it's place in a container to be dropped by parachute.

For the soldier it was a failure, and instead used for local transports on the airfields and other military places.

Look at the third picture above.

John Dolphin took over this concept after the war and started an own company for production. The cycle became though not so popular as it had a to weak engine. The example on the picture shows a home developed model equipped with a bigger engine and has also lights and brakes front and rear.

Most surplus cycles were sold to USA and it became popular among farmers. It was not equipped to get permission to be driven on regular roads. In England were 27000 ex sold after the war.

Two wheel drive mc. Built by Berthold Ericsson. Ref 1

Unique two wheel drive mc.
Transcription from Autohistorica in the museum.

In the beginning of 1930 Berthold Ericsson was racing with a mc which mainly was home made. The frame and wheels are mainly from an OEC standard motorcycle which from the beginning had a 750  cc JAP engine.

In order to make a winning machine it had to be trimmed. First the "small" engine was change to a 1000 cc Jap. Later this motor was bored to 1370 cc.

Chain drive construction. Ref 1
Chain drive construction. Ref 1
As spectators and organizers had no knowledge what OEC was (English mark), the Swedish mark Rex was contacted. They were willing to deliver details for this local built mc and a name change was also made to REX.

Detail of engine. Ref 1
Detail of engine. Ref 1
After some years racing an engineer Einar Stormark was contacted. He was working with experiments with two wheel drive.
In the autumn 1934 the rebuilding of the cycle was started. Stormark made drawings and calculatings while Berthold Ericsson did the welding and machining.

In order to take advantage of the high engine power, 90 ps, two wheel drive was a definite advantage. This made that wheel spin was reduced.

In the spring 1935 the machine was ready and the first competition was raced in Malmsjö Hill climb on the 22 of April the same year. During this year this mc was raced in about 10 hill climbs and almost all were victories and also a Swedish Championship.

Detail of JAP engine. Ref 1
Detail of JAP engine. Ref 1
After the end of the season 1935 almost all parts of this mc was dispersed, although the most important constructive parts were kept. Those were parts like driving sprocket wheels, fork and others.

By an energic "detective work" during later years the different original parts could be found at the owners. Among these the most important is the engine. This has been used in several other mc:s and last in a midget car.

Chain drive construction. Ref 1
Chain drive construction. Ref 1
Expect that this rare two wheel drive mc, it is a typical motorcycle from the thirties. Most part were accessed from different mc models.

Of course it is with great happiness one now can see this mc again can be an important show at Technical museum in Stockholm. It is though on display at Åssa Factory museum Åtvidaberg. Here today youth can see a rare two wheel drive motorcycle from the thirties.
