Introduction INDEX

The Swiss VéloSoleX was first assembled -but soon afterwards produced- at the  Hispano-Suiza factory of Vernier near Geneva from 1948 until 1957. Only the legendary and very strong 'swan-neck' -shape frames were delivered during these years.

Andreas Wehren

Around 1958 this Hispano-Suiza VéloSoleX was replaced by the VéloSoleX (non-'swan-neck'-type) models imported from France.

The luggage-carrier was made from 4mm wire with a rectangular toolbox at the end. It is similar to the French ones found on 26" frames but now with an additional specific clip being a fixed part of the luggage-carrier (to secure transported objects).

All engines had comb-shape (deflection-type) pistons with cylinder volume originally 45cc and later 49cc.


Soon after the introduction in Switzerland, most parts were genuine Swiss-made.

In 1949 Hispano-Suiza had already 74 sub-contractors to help producing this VéloSolex.

HS part-numbers always contain 6 digits and start with "510", the following 3 digits correspond with the same 3 digits used in the French VéloSoleX nomenclatura.

Die-casted parts of the engine like crankcase, cylinder-head, ignition-plate and fuel-pump are often marked with the producer's name 'Bühler' (starting with the 2nd generation of the HS VéloSoleX and ending during the 4th generation).

  HS 510346  
  HS 510937
 Bühler 6156-2   
  Most of the die-casted Bühler parts clearly show the "510xxx" HS part numbers but can also show numbers used by Bühler internally: these numbers contain 4 digits - 1 digit (separated by a dash).

The complete engine numbers and the complete frame numbers from Hispano-Suiza always start with the letters 'HS'

So if you can identify such 'HS' numbers on you own VéloSoleX it should be a real (and rather rare) Hispano-Suiza VéloSoleX !

However, some restauration projects used French engines or crankcases (without the starting HS identification).

The company Hispano-Suiza INDEX

The company  Hispano-Suiza, known by many people because of their rich history of luxury cars, dates back from 1898.

Concise overview of the company-start (details from  for the period 1898-1904):

¨La Compañía General Española de Coches Automóviles Emilio de la Cuadra, Sociedad en Comandita¨, was founded in 1898.

They employed the Swiss engineer Marc Birkigt in 1899, but soon afterwards the company went bankrupt (1901).

In the following year 1902, José María Castro Fernández, together with Marc Birkigt, founded a new company named ¨J. Castro, Sociedad en Comandita, Fábrica Hispano-Suiza de Automóviles¨ to continue the production of luxury cars.

Again in 1904 the business broke down and had to be re-financed by Damià Mateu i Bisa and Francisco Seix Zaya.

A new company in Barcelona with Damià Mateu i Bisa as president, Francisco Seix Zaya as vice-président and Marc Birkigt as technical director was called:

« La Hispano-Suiza Fábrica de Automoviles SA »

Soon afterwards this company was so successful that also a French subsidiary was opened in 1911.

From these activities we may assume the start of the relationship between the companies Solex (Marcel Mennesson & Félix Goudard) and Hispano-Suiza (Marc Birkigt), which consisted of supplies of Solex radiators and carburetors to Hispano-Suiza.

During the Spanish civil-war (1936-1939), Marc Birkigt left Spain. Back in Geneva he founded in 1938 the ¨Hispano-Suiza (Suisse) S.A.¨

The idea of Marc Birkigt to start the production of the Hispano-Suiza VéloSoleX in Geneva 1948 was also meant to improve diversification (from the dominating focus on military production since the second world war).

Hispano-Suiza used the Vernier factory near Geneva for it's VéloSoleX activities:

Marc Birkigt, born 1878 in Geneva, passed away 1953 near that same city.

His son Louis Birkigt, now being the main family-owner of the ¨Hispano-Suiza (Suisse) S.A.¨, took over until selling his company in the seventies to Oerlikon-Bührle and partly to Sulzer. Premises in Geneva were finally completely closed in the mid-eighties.

An extensive overview of the overall Hispano-Suiza company from its founding up to the business scope in the late 90-ties, can be found in a book written by Michel Polacco: "Hispano-Suiza, the future with a legend", available in English and French.  Recently we saw the brand Hispano-Suiza appearing again at the Geneva-fair March 2019 (see notice of the exhibition in March 1949)

1949: a critical year for the Hispano-Suiza VéloSoleX INDEX

Hard to imagine what was required in 1949 to use a VéloSoleX in Switzerland...

- Being 18 years old

- Driver´s license like for heavy motorcycles

- License plates in front and at the back (although it was not needed to mount the plate in the front)

- A speedometer (but you could apparently register your VéloSoleX  without this) 

- However, in  detail  this looks like quite a bit more complicated.... (partly based on the Swiss regulations from  6 August 1947  and those regulations from the 30-ties where ¨cycles with auxiliary-engines were still unknown).

The Hispano-Suiza company in Geneva knew that these regulations in Switzerland had to be changed as soon as possible.

Otherwise the market for the VéloSoleX in Switzerland would have no chance at all.

Arguments that the Hispano-Suiza company in Geneva put forward to the authorities:

- Main point was their very difficult economical situation: being focussed on light-arms production, they suffered from an embargo to export. Internal demand from the Swiss army was far insufficient after the second world-war. They desperately needed  ¨peace-products¨. 

- A substantial amount of money was already invested to set up the production of the VéloSoleX and Hispano-Suiza had engaged  74 sub-contractors  all over the country. Employment advantages were substantial.

- They refered to France, Italy and Holland, being very successful VéloSoleX-countries, who had already changed their regulations in this context.

- At the same time, they mentioned  statistics  from the city of Paris showing that the VéloSoleX-users were one of the most careful drivers with the lowest accident-rate....

- Since VéloSoleX-owners from these countries were not allowed to enter Switzerland either, this could become a  constraint for the Swiss tourist-industry

So the Hispano-Suiza company decided to start influencing and convincing the Swiss authorities in Bern: In summary their   considerations  and  conclusions:  .

(Earlier they had tried to discuss these matters with Swiss police authorities,  but that was no success at all ...)

VéloSoleX Hispano-Suiza exhibited at the Geneva-fair 1949 INDEX

¨Salon International de l´Automobile"

Published in the ¨Van der Heem¨
company-letter nr. 223

Text in Dutch: ¨..... even in this mountain-country there appears to be a market for the Solex.....¨

In a the Hispano-Suiza papers we found the  comment that there was also a test-circuit at this Geneva-fair in 1949 where ¨thousands of people, both man and woman, from 12 till 70¨ tested the VéloSoleX and learned to use it in a correct way within 30 seconds !

Remark: 70 years later, Hispano-Suiza was presenting again at the Geneva-fair in March 2019 it´s capabilities to their world of wealthy admirers....

You can have a look at: 

Homologation for the Hispano-Suiza VéloSoleX INDEX

 From Franz Kränzlin we received copies from official  Swiss homologation documents describing various details of both the 45cc and 49cc Hispano-Suiza VéloSoleX versions.

From these documents we might conclude that the 45cc production was replaced by the 49cc version at engine-number 14251 and further that the Hispano-Suiza VéloSoleX production was (apparently) completely finished at engine-number 14750

Homologation of the HS-VéloSoleX
with 45cc engine: number 254

Homologation of the HS-VéloSoleX

Source: archive documents from the Swiss organisation for the registration & control of vehicles ('Strassenverkehrsamt'), based on the official publication of the Federal Department of Justice and Police in Switzerland (Eidgenössisches Justiz und Polizei Departement /Département fédéral de justice et police / Dipartimento federale di giustizia e polizia). 

Although these official documents show the last frame-number being 14750, several owners reported us engine- and frame-numbers towards 17000 delivered until december 1960 (see example of the registration of a late 4th generation HS-VéloSoleX on 15-12-1960 with frame-number 16950 and engine-number 16209 in Basel):

This might bring us to the conclusion that the production of the Hispano-Suiza VeloSoleX continued after 1957. But such conclusion would be completely wrong ! The official Geneva state-archives confirm the end of the production in 1957 (Ref:

An explanation could be rather simple: the production-level of the Hispano-Suiza VeloSoleX in Geneva was far above the demand in the late 50-ties. So there was a surplus of them still available for selling to the Swiss customers until the early 60-ties) ! Apparently there is a rumour in the city of Geneva that the excess stock of engines have been thrown in the lake of Geneva......

1948 - 1950

HS 1 - HS 2.200

Transfert VéloSoleX Hispano-Suiza

    Like all later HS-generations, also the first Swiss VéloSoleX can be distinguished by a prominent text on the central frame-tube:  

    "VéloSoleX Fabriqué par HISPANO-SUIZA (Suisse) S.A. Genève" 

    although this history is strongly connected with "Hispano-Suiza" as producer of the Swiss VéloSoleX, the legal entity responsible for distribution of this Solex however, was the S.A. SIVAM (Societé d'Importation des Véhicules À Moteur) 3 Rue du Léman, 1200 Genève.

    this corresponds with "Van der Heem" in The Hague (Holland) as manufacturer of the Dutch RijwielSolex and "Stokvis" in Rotterdam as distributor (and commercially reponsible in the Benelux countries including former overseas territories).

    later, the SIVAM S.A. entity was replaced by SOVEDI S.A. (Vente et distribution en Suisse du VéloSoleX).

    Characteristics for the 1st generation HS-VéloSoleX:
      • The letters 'HS' (in front of the engine-number) have been 'stamped' in the French-made crankcase

        (like the letter 'H' in Holland for the oldest assembled engines in 1948 by Van der Heem in The Hague)

      • All engine-parts were imported from France, the engine was assembled in Geneva

      • From the start, some of the 26" 'Swan-neck' frame-parts applied in Switzerland were slightly different from the French versions (e.g. less flatter mudgards). Unknown which frame-parts were imported.
    Engine details: 
    • 45cc two-stroke engine, stroke-bore ratio 40 x 38 

    • deflection-type ('comb-shape') piston

    • external transfer-ports in cylinder are closed by a 'Zamac' (=aluminum-alloy) cover

    • cylinder with external gas-transmission (it's the one at the left")

    • cylinder-head fixed with 3 bolts (it's the one at the left with the large holes) 

    • spark-plug mounted vertically on cylinder-head covered by a black isolation:

    • 'peppertin'-shape air filter above carburetor ('carburateur à cloche') it's the lower one at the right side:

    • carburetor with 4mm venturi, the air-slide controller points to the driver (it's the one on top)

    • no engine-cover (fixed on fuel-pump) yet

    • zamac exhaust-manifold with steel connection-pipe towards exhaust

    • not yet a ‘grease-pot' (boîte à graisse) on top of the crankcase

    • French ignition-base with metal-plate around Zamac-center

    • French (black-coloured) lighting and ignition-coils 'SEV'-brand

    • French aluminum flywheel-cover fixed with two closing screws (it's the cover and the ignition at the left): 

    • crankcase-cover fixed with 5 bolts (it's the one at the left): 

    • non-metal fuel-cap with 'riffeling' in black (at the right, the one at the left is the metal fuel-cap in gray as used in France and Holland).

    • snap-system at the leftside of the engine to separate the engine from the front wheel (left side on the picture)

    • steel exhaust-tailpipe connected with an aluminium pot and aluminium part to the cylinder

    • large 55mm diameter (carborundum) drive-roll (it's the one on top):

    • Rolls

    • text on crankcase (in driving direction) :

    •  26" swan-neck frame with a fixed installed clip at the luggage-carrier and a toolbox at the rear.

    • toolbox

    •  the frame has at the rear (left side) a fixed installed lock "ML"-brand or 'Hebie'-brand:

    • ml lock

    •  Hispano-Suiza stamped the framenumber into the key-holder

    • keys 2184

    •  black soft grip (rare if it has survived until now.)

    • Rearlight-old

    • comfortable 'brown-colour Viktor Raetzer'-brand black-colour saddle with 3 springs, text: 'VeloSoleX' at the back. This saddle is broader and a bit more flat than the regular French ones. Thr two springs at the back are "twisted" 

    • westwood-type chrome-plated rim 650x38B (i.e. lower 'chapeau gendarme' dome-shape than French ones 650x45B) with 36 spokes (2.2mm) from Swiss-production 'Drahtwerke Biel'

    • wheel-hubs have inscription „EDCO“ (= 'Edouard Dubied & Co' in Couvet / Val de Travers).

    • Bull cord 650 x 45B tyres from the Dätwyler company in Altdorf (written on the packing: "Travail Suisse conscientieux / Zuverlässige Schweizer Arbeit").

      Text on the black tyre:

      TYPE VéloSoleX
      650B Dätwyler

    • Dätwyler Bull Cord 650B

      Note: regular Michelin 650B tyres mostly don't fit very well at these rims (too loose - be careful when trying, you might miss some front-teeth afterwards... we're not responsible anyway).

    •  rear-light is regular French-made 'Soubitez'-brand, tiny aluminum housing with small red plastic cover, no rear-reflector 

    • Rearlight-old

    • small rectangular toolbox at the end of the luggage-carrier
    • like the French VéloSoleX, decoration of all frame-parts with hand-painted red & white coloured lines 

    • apparently with a "VéloSoleX"-bell, we have not seen it "in the wild" so far. Who could send photos ?
    • bicycle-type airpump at the luggage carrier (right side)

    • solid parking-stand (aluminium die-cast). It seemed to be a standard delivery, not just an option.

    • option: spare fuel-tank in a triangular-shape with brass-metal cap for mounting at the left side of the luggage-carrier (rather rare !)

    • option: ¨VK-brand¨-speedometer. we received remarks that this accessory (mentioned in our first versions) had nothing to do with the VéloSoleX.

      However, we learned that this speedometer was a formal obligation in Swiss legislation during the late 40-ties for any motor-cylce, including the VéloSoleX !

    • this professional ¨VK-brand¨-speedometer. was produced by the Swiss wrist-watch manufacturer Heloïsa in Lengnau/Longeau (Canton Berne). Typical Swiss service: an extensive catalogue with spare-parts was made avalaible too:

    • VK-parts

    • recently a brand-new ¨VK¨-speedometer. was offered (for a very nice-price) in the Dutch marketplace, however, we reacted too slow....

    • VK-2019

    • since this first generation HS-VéloSoleX did not have an engine lifter yet, sometimes a rare accessory was used to connect the engine to the front wheel and lifting again the engine after finishing the ride: "the basculex"


      "the basculex" was mounted with 2 special bolts on top of the cylinderhead. with a steelwire it could be connected with the existing snap system at the left below the flywheel (we still have a few new wires available.. .)




    • dealers were advised to only use spark-plugs "V 36 A" for VéloSoleX from SEV Marchal

    A remarkable VéloSolex journey from Alwin Reithaar in 1950 INDEX

    These are the remarkable photos from Alwin Reithaar who travelled in 1950 some 15.000km with a first generation Hispano-Suiza Vélosolex from Switzerland via Italy along the coast of the Mediterranean to Algeria and Morocco, continued via Spain and France to Great Britain and up to Norway and Sweden before finally (via the Dutch Solex manufacturer Van der Heem and the distributor R.S. Stokvis in The Hague in Holland) returning to Switzerland......


    (click on thumbnails to enlarge)

    Alwin Reithaar's trip in 1950 was also published in the Dutch magazine 'Op de Solex' (edited by R.S. Stokvis in The Hague, Holland) It inspired and encouraged many Dutch 'Peperbus' Solex owners to explore Europe in the early 50-ties


    Publicity dedicated to Alwin Reithaar's trip in 1950


    Alwin Reithaar's correspondence with the Management of VéloSoleX Hispano-Suiza in Geneva, early 1950

    This contract was to obtain a VéloSoleX at a reduced price for his European trip. However, in Geneva they would like to receive results for their money... So this price reduction would be according to completed kilometers, otherwise the regular price had to be paid afterwards......

      alt txt
    alt txt
    Spare-parts had to be sent regularly to various European cities..... An overhaul service was offered at the Solex organisations in the UK and in Holland. And.... last but not least, he will receive his Solex for free

    alt txt
    alt txt
    In Oslo the spark-plug cable lost connection... so also the fuel-pump had to be removed... but in the meantime an extra gasket for the fuel-pump connection to the crankcase was invented.

    alt txt

    alt txt

    5.000km from 15.000km had been achieved already at the moment that this newspaper advertisement was published early 1950. The remark "sans panne" can be seen different after having read the notebook of Alwin..... While he was sending positive reports to Geneva, at the same time, the letters to his brother presented a quite different view on the experiences regarding his VéloSoleX.

    Remark: Alwin Reithaar, having used a first generation HS VéloSoleX with engine number 2155, enables us to correct our previous 'estimate' of the 1st generation production numbers, from HS 1 - 2000, into a new 'educated estimate' of HS 1 - 2200

    Alwin Reithaar passed away in october 2018 at the sacred age of 96. Thank you Alwin for your amazing stories, photos, documents and trust !

    in a future version)....



























    Advise: only use original HS-VéloSoleX spare-parts ! However, if your nearest HS-VéloSoleX dealer ran out of stock, you might consider to cast missing Zamac VéloSoleX-parts yourself :-)

    Technical do's & don'ts,

    (Joan: Just One Anomalous Nerd) 

    for the time being, we just have the original VéloSoleX repair-guides from Courbevoie available :-)

    We know that this French repair-guide from the VéloSolex Courbevoie organisation has been published in English (and Dutch) too.

    Could anyone provide us with this English version ? Has anyone seen this guide as HS-version in German/Italian/French ?

    Please let us know !
















    (similar) 49cc version will be published later :-)

    The "post-HS" era: the sixties

    somewhere around 1958 SOVEDI S.A. started to import the VéloSoleX from France: this could have been the model 660 (with the same engine as the 4th generation HS but with a non-swanneck frame). however, more probably it was the French model 1010 (same frame as the model 660 but with a cylinder without external transfert ports: the so called "double transfert" with "dome-shape piston" or "piston bombé"). you can identify such engine by its non-keylock-shape airfilter:

    all later engines had similar airfilters: via the French Solex model 1400, and afterwards the models 1700, 2200, 3300 and 3800 (with automatic clutch):

    although the automatic clutch became the standard in our Solex-world, we still prefer the traditional and quiet way of Solex riding without such clutch ("embrayage automatique")...... however, our famous "curé" did not seemed to be stressed at all (maybe due to these peaceful sixties)......


    The "pre-HS" era:
    the mid-fourties

    during the year 1947, the Solex organisation in Paris-Courbevoie was interested in selling licences towards 3rd parties inside and outside Europe

    they succeeded soon in Switzerland with Hispano-Suiza in Geneva, in Italy ("VéloSoleX Torino") and in Holland ("RijwielSolex Stokvis Rotterdam")

    quite a lot of the VéloSolex 1947 models were sent from Courbevoie to these cities for testing purposes

    unfortunately almost none of these testing vehicles have survived, although we happened to discover certain remainings of them

    maybe there are local collectors who were lucky too in finding such historical parts

    for determining these "pre-HS" parts, we add hereafter some typical images of such engine from the year 1947

    • cylinder-head with large 24mm SW26 (thread M18x1.5mm) spark-plug, instead of regular 18mm SW21 (thread M14x1.25mm):

      (merci David M.)

    • crankshaft consisting of two parts

    • ignition with red "SEV"-coils and condensor on top:

    • carburettor with an extra (oil-mixture and/or 25% alcohol) fuel-adjusting screw:

    • large Ducellier aluminium head-lamp:

    • closed aluminium exhaust-pot:

    we would be grateful to learn about such "pre-HS" discoveries from you !

    press-photo presenting the 1947 version of the VéloSoleX in France:

    based on this 1947 model, Stokvis and Van der Heem assembled the prototype of the first Dutch "RijwielSoleX" (we assume that Hispano-Suiza in Geneva, like the VéloSoleX Torino organisation in Italy, was also busy with a similar excercise):

    Remarks INDEX

    In our older versions, some omissions have been included regarding the first generation 26" Hispano-Suiza Vélosolex (i.e. some accessories have been described as 'regular production-specification', like the brown ´Viktor Raetzer´ saddle and the ´large-sized Lucifer-brand´ head-light). We derived such information from our superb 1st-generation HS VéloSoleX which was found after a profound sleep of 50 years in a "near-new" showroom state. However, it became clear that the original owner must have been a 'mordu' professional who replaced many standard-parts with better or newer ones. For instance, he (or she ?) added an engine-lifter, replaced the standard headlamp by two better ones, replaced the 4mm carburettor with a newer 7mm version etc. Servicing the engine it became also clear that this person knew very well how to tune the engine for improved performance ! Finally we were able to correct the earlier omissions by studying the photos from Alwin Reithaar.
