Overview
VéloSoleX is a French motorized-bicycle brand whose name became closely associated with a distinctive, economical moped powered by a small engine mounted above the front wheel. A roller pressed against the tire transmitted power directly to the wheel, allowing the vehicle to retain much of the appearance and simplicity of a bicycle. In France, the product was commonly called a Solex. The brand emerged from the French industrial company Solex, which had originally made technical equipment such as centrifugal fans for automobile radiators, carburetors, and micrometers. The motorized-bicycle concept was developed during the Second World War and entered the market in 1946. Its combination of low weight, mechanical simplicity, modest running costs, and bicycle-like handling made it particularly attractive to schoolchildren, students, workers, and other riders seeking inexpensive personal transportation. Advertising presented it as “the bicycle which drives itself,” emphasizing convenience rather than performance. The core design evolved through a long sequence of models. Early 45 cc versions were followed by the 330, 660, 1010, 1400, and 1700 models. Later generations introduced dedicated frames, improved engine output, automatic clutch operation, air cooling, stronger braking, and more practical controls. The S3800, introduced in 1966, became the best-known and most widely sold version. Its square-tube frame, front-mounted engine, and recognizable silhouette made it an enduring emblem of postwar French everyday mobility. Variants included more elaborately finished Luxe and Super Luxe editions, the compact F4 children's model, the small-wheeled Micron, and the folding Plisolex. Solex also explored vehicles that departed from the signature front-roller arrangement. The Flash, later called the 6000, used shaft transmission, disc brakes, and a fan-cooled engine, while the Tenor used chain transmission and engines supplied by outside manufacturers. These products broadened the range but did not displace the classic roller-driven format in public recognition. Ownership changed several times over the brand's history, with the business passing through Dassault, Renault, and Motobécane/MBK before becoming associated with VéloSoleX. French production continued until 1988. The design subsequently survived through licensed or related production in China and Hungary; Hungarian production ended in 2002. Manufacturing returned to France in 2005 through Mopex, which introduced the Black'n Roll S4800, a modernized interpretation of the traditional concept. The brand later moved toward electric mobility. Products associated with the modern VéloSoleX range included the folding Velosolex electric bicycle, the pedal-assist Solexity, and the e-Solex electric bicycle. These products adapted the brand to contemporary regulations and urban transport needs while retaining an association with compact, accessible two-wheeled transport. The traditional Solex has also remained culturally visible through films, literature, vintage-vehicle communities, and nostalgia for postwar French popular culture. Sources describe more than seven million units sold worldwide, with the product marketed in approximately seventy countries, although the exact total and current production scale require verification from primary company records.
History
VéloSoleX originated within Solex, a French engineering and manufacturing company based near Paris in Courbevoie. Before developing its famous motorized bicycle, Solex produced industrial and automotive components, including centrifugal fans for car radiators, carburetors, and precision measuring instruments. During the Second World War, the company developed the concept of adding a small assist motor to a bicycle. The engine was mounted over the front wheel and drove it through a friction roller, a configuration that allowed a relatively ordinary bicycle frame to become a powered vehicle without the complexity of a conventional motorcycle transmission. The first commercial versions appeared in 1946. The early 45 cc model delivered limited power and used a simple operating principle; in its initial form, the rider had to restart the engine after stopping. Successive models increased reliability, power, braking capability, and ease of use. The 330 and 660 retained much of the early architecture, while the 1010 and 1400 refined the engine and frame. The 1700 introduced an automatic clutch and air cooling, making the vehicle more practical for everyday use. The S2200 added further engine improvements, and the S3300 introduced a square-tube frame and a rear drum brake. The S3800, launched in 1966, became the defining model of the brand. Its configuration remained recognizable while later versions added color, upgraded finishes, larger wheels, and a twist-grip control. The model's low operating cost and approachable riding characteristics helped it become common among young people, students, employees, and urban commuters. It was promoted as an economical vehicle that combined the familiarity of a bicycle with the convenience of a motor. Smaller and specialized products complemented the main range, including the children's F4, the compact Micron, the folding Plisolex, and export-oriented models such as the 4600. Not every Solex product used the traditional front roller. The Flash, later renamed the 6000, used an axle transmission, disc brakes, and fan cooling. The Tenor used a chain drive and was offered with engines from Franco Morini and Anker Laura. These models demonstrated attempts to compete in broader moped categories, but the roller-driven VéloSoleX remained the brand's defining product. The business changed hands during its history. Ownership successively involved Dassault, Renault, and Motobécane/MBK, before the VéloSoleX name became associated with a later owner and operating structure. The original French production run ended in 1988. Licensed or related production continued outside France, particularly in China and Hungary, allowing the design to remain available after domestic production stopped. Hungarian production ended in 2002. In 2005, production returned to France through Mopex with the Black'n Roll S4800, a modernized development related to the classic S3800. The brand subsequently explored electric urban transport. By the early 2010s, its range included the e-Solex, a folding electric bicycle, and the Solexity, an electrically assisted bicycle using a different transmission concept. The range also included an electric Velosolex model designed for compact city use. These products repositioned the marque for changing emissions rules, urban transport patterns, and interest in low-speed electric mobility. VéloSoleX became more than a vehicle brand. Its appearance in French cinema and literature helped establish it as a symbol of ordinary postwar life, modest personal freedom, and recognizable French design. Its appearance in works including Mon Oncle and later international films reinforced its cultural identity. Although production figures vary by source, reference material attributes more than seven million units to worldwide sales and distribution in roughly seventy countries. The precise current corporate ownership, operating status, and production volume are not sufficiently documented in the supplied sources and should be confirmed through contemporary company records.

45 cc VéloSoleX
The initial commercial VéloSoleX used a small 45 cc engine mounted above the front wheel. Its friction roller drove the tire directly, preserving the basic proportions and riding character of a bicycle. The early engine produced approximately 0.4 horsepower and lacked a clutch, so the rider had to restart it after coming to a stop.
