Solex began in 1905, as two young French engineers, Maurice Goudard and Marcel Mennesson, producing engine parts. They made radiators, mostly for large trucks and buses, before and during World War 1. After the war, Solex shifted from radiators to making carburetors.
Solex carburetors became the company’s most famous product, used on many European automobiles for decades. They also made lots of other things, like excellent micrometers.
VeloSolex (SolexBike) was developed during WWII while France was occupied by Germany. In 1940, after decades of interest in “bicycles with emergency engines”, the first front engine prototype was unveiled.
In 1946, after 5 years of testing, the humble hybrid went into production.

The VeloSolex 3800 had reverse brake levers and a non-self-closing twist throttle. Most had Seima tail lights with no brake light. Only some US and Canada models had Maly tail lights with a separate brake light on top.
All 3800 motors from May 1966 to 1975 had an ID badge that says 1966. That was the year of the design approval, not the year it was made.
By 1967 4 million VeloSolex’s were sold. Improvements were made year after year. The Solex motor bike became a household item in France and many parts of Europe.

1975 Renault: In 1974 Velosolex sold part of their production facility and rights to Renault. Here is a Renault 5000 and a Renault Tenor. But Renault sold the production to Motobecane (MB), in Dec 1974, after only a month.
1975-82 Motobecane (MB): Motobecane kept the old chrome VeloSolex side stickers until late 1977. Here is a 1977 Motobecane 50V, a 1977-80 Motobecane S 3800 and Motobecane 5000. At the same time VeloSolex continued to produce mostly domestic S 3800s, up to 1986.
1983-88 MBK: Motobecane was bought out by Yamaha in 1983, restructured and renamed MBK. The 1986-88 MBK S 3800 stickers only said Solex, in script.

The Solex fuel pump membrane and maybe the plastic seats and balls are needed often to replace deteriorated 30-50 year old ones. It’s easier to replace the entire pump, membrane, and membrane seat, but more costly. When the top cap or post is unscrewed, the top check ball easily falls out and gets lost. Often a not working fuel pump only needs a ball, or a new membrane. The pump check balls can be tested by blowing and sucking through a piece of small rubber hose or fuel line. The lower line only blows and does not suck. The upper line only sucks and does not blow.

so the brake shoes and brake plate also changed.

1962-74 Solex 3800 USA Wiring: this content courtesy of BrianSolex
Yellow – main power from stator to switch paddle (power for the lighting exits the stator via the serrated stud; there is no wire connection between the serrated stud and the switch. The switch paddle must contact the serrated stud when the switch lever is turned counter-clockwise)
Red – power from headlight switch paddle, through spring and bronze strip, to headlight.
Blue – power from bronze strip to tail light wire
Green – ground (wire from headlight to fuel pump screw)
*Note: the 1966-72 S 3800 USA (and the S 3300) is similar, but instead of a ground wire, there is a ground tab mounted on the front of the fuel pump. The tip of the bulb touches the tab.

http://www.velocruz.com/home.htm Velocruz Inc in Utah USA still carries most Solex S 3800 parts, and sometimes used bikes, but not any more new ones. Velocruz founder Tommie Matthews brought back the Velosolex to the USA in 1998, becoming the exclusive US distributor for Impex, the manufacturer in Hungary. Son Jeff Matthews runs Velocruz now. The Hungarian S 3800, produced from 1999 to 2005, was well made, and nearly identical to the 1986-88 French S 3800.
