Dollar

There is a framed photograph, reproduced often enough in French motorcycling circles that it has become a kind of totem, showing a small factory floor at Charenton, on the edge of Paris, sometime in the mid-1920s. Rows of light, four-stroke singles sit half-assembled, and somewhere behind the scene is a woman named Jeanne Delachanal, running a motorcycle company that carries her late father's bicycle business into a completely different age of machinery. She is not a household name even among people who know their prewar French marques cold. But Dollar, the brand she helped launch, deserves better than a footnote, and its story is stranger and more interesting than the usual founder-and-factory tale.

Origins: From Locksmiths to Bicycles to Motorcycles

The roots of Dollar go back further than any motorcycle. The lineage starts with Établissements Foucher, a precision engineering and locksmith firm where a young Louis Delachanal (1857–1920) began his career, with the family's mechanical involvement traceable to around 1850. Delachanal married Juliette Foucher, his employer's daughter, and in 1900 his father-in-law, Eugène Foucher, handed him control of the business. Ten years earlier, in 1890, Delachanal had already founded the Omnium bicycle brand, which built machines under both the Omnium and Spencer names.

Louis Delachanal died on November 14, 1920. His daughters took over the Charenton-based business, and it was Jeanne Delachanal, together with her husband, who made the decision to move the company into motorcycles. Louis had been dead three years when the pair christened their new machine "Dollar" and gave it a Native American head as a logo — a name and image chosen to tap into the fascination with America that swept France after the First World War. It is an odd bit of branding for a firm rooted in nineteenth-century Parisian craftsmanship, but it worked, and the name stuck for close to two decades.

The Early Machines

Dollar's first motorcycle was shown at the Paris Salon in October 1923, with proper production following in 1924. It was a modest 125cc machine, but a genuinely clever one for its class: a four-stroke with overhead valves, at a time when most small-displacement machines on the market were simpler two-strokes or side-valve units, built as an integrated engine-gearbox block with two speeds. The engine came from the Swiss manufacturer Moser, and it proved a good bet — light, fast for its size, and reliable enough to win races and set records in the hands of riders like Druz, Clech, and Lambert.

Success bred expansion quickly. By 1925 and 1926, Dollar had added 175cc and 250cc models to the range, and by 1926 the catalog had grown to a dozen models, including a triporteur (a three-wheeled delivery machine), all still running Moser engines. In 1927, the company outgrew Charenton and moved to a new factory in Joinville-le-Pont, on the Marne just southeast of Paris. It was a year of real transition for the marque, and it set up the decade that would define Dollar's reputation.

The Golden Era

The defining relationship of Dollar's history began in 1927, when engines built by Maurice Chaise arrived in the lineup. Chaise had spent 1907 to 1921 as chief engineer at Rhône, the firm that became part of Gnome & Rhône, before striking out on his own to found Établissements Chaise & Cie as an engine manufacturer in 1921, working with Louis Edderlé, another engineer with roots at the same company. The Chaise engine that showed up on Dollar chassis in 1927 caused a stir in the French trade: it ran an overhead camshaft and a hemispherical combustion chamber, sophisticated architecture for a mid-displacement production motorcycle at the time. By 1929, Dollar's production machines ran almost exclusively on Chaise power, though the firm also fitted proprietary British and Swiss engines from JAP and MAG over the years, keeping its options open the way most French assemblers of the period did.

The late 1920s and early 1930s were Dollar's high-water mark. New models appeared nearly every year, the fit and finish of the machines earned a genuine following, and the overhead-camshaft engineering that Chaise brought to the marque gave Dollar a technical edge over a lot of the competition. The 350 R2 earned French army approval as a supply motorcycle, a useful and lucrative distinction for a manufacturer of this size. Dollar also brought in the flat-twin Majestic engine under license from its creator, Georges Roy, adding another distinctive unit to a range that, by the early 1930s, spanned from tiny 98cc runabouts up to the big 750.

The high point, and the model still cited whenever Dollar comes up among people who collect this era, arrived at the 1932 Salon: the Type V, a 750cc four-cylinder machine with shaft drive. It was built in tiny numbers — sources consistently put the total at around ten machines — which makes it one of the rarest French production motorcycles of the interwar period, a genuine engineering statement rather than a volume seller. Dollar also brought in the illustrator Géo Ham to handle catalog art and advertising, giving the brand a visual identity to match the ambition of its engineering.

Racing

Dollar's competition record was built less on grand prix glamour and more on the unglamorous, demanding work of French domestic motorsport in the 1920s and 1930s: hill climbs, reliability trials, and record attempts. The early 125cc Moser-engined machines proved surprisingly quick in period, and riders Druz, Clech, and Lambert took wins and set records on them in the mid-1920s. Later, the 250cc Type P4 finished tied for first in class in the Tour de France motorcycle event with rider Rasser aboard. These results, combined with the general reputation Chaise-engined Dollars built for themselves in French competition, gave the marque real credibility in a crowded field of domestic manufacturers, even without a marquee international grand prix campaign to point to.

Landmark Models

The model range through the early 1930s reads like a survey of what a serious French manufacturer could offer a buyer of the period: the Type U (350cc JAP side-valve), Type V (500cc JAP side-valve), Type Y (350cc MAG) and Type X (500cc MAG) all ran 1930 to 1931; the Chaise-engined Type R2 350cc arrived in 1930, followed by the Type S2 500cc overhead-valve Chaise that stayed in the catalog from 1930 to 1935. The Type R4 Luxe, a 350cc Chaise machine, ran from 1931 to 1934. The 250cc Type P4 Luxe and its sportier P4S sibling carried Dollar through the early 1930s. And, of course, there was the Type V4 — the 750cc four-cylinder, shaft-drive machine of 1932 and 1933 that remains the brand's calling card among collectors.

Later in the decade, as the range narrowed, Dollar leaned on smaller Chaise-powered singles: the Type P35 and P36 250cc models of 1936 to 1939, the P36 notable for its inclined cylinder, along with the R36 and the R36 "Normandie" of 1936, the R9 350cc inclined-engine Chaise machine, and the S536 in both Pullman and Standard forms, produced from 1936 through 1939. It is a long, steady list, and it shows a company still developing new variants right up until the end — even as its financial footing had become shaky.

Ownership and the Slide Toward Closure

Dollar's independence did not survive the economic pressure of the early 1930s. The firm had become financially entangled with its engine supplier, and by most accounts the takeover by Omnium Métallurgique et Industriel (O.M.I.) — the parent concern behind Chaise — came in December 1931, weakening a company already strained by the wider economic crisis. Whatever the precise month-by-month sequence, the mechanism was clear enough: Dollar, heavily indebted to its engine maker, was absorbed into the larger group. Company correspondence from the later 1930s carries the OMI address on rue A. Lançon in Paris's 13th arrondissement rather than the old Joinville-le-Pont works, a small but telling sign of where control now sat.

The mid-1930s brought further strain. The social upheavals of 1936 — the wave of strikes and factory occupations that swept French industry that year — hit Dollar along with the rest of the country's manufacturing base, and the marque never fully recovered its earlier momentum. Production continued in reduced form through the late 1930s, but the outbreak of the Second World War brought Dollar's operations to a stop for good. No revival under the original ownership followed. Unlike some French marques that found new owners and new names after 1945, Dollar simply did not come back.

Dollar Today

What survives of Dollar exists almost entirely in private collections and museum stores, and the numbers are small enough that any surviving example — particularly anything from the Chaise era or one of the handful of 750 V4s — draws serious attention whenever it surfaces at auction or on the show field. In February 2023, more than twenty Dollar motorcycles built between 1926 and 1936 were gathered for display at the Rétromobile show in Paris, marking a century since the marque's debut and giving enthusiasts a rare chance to see the range assembled in one place, from the early Moser-engined lightweights through to the later Chaise singles.

Dollar is not a name that means much outside a fairly narrow circle of French prewar motorcycle specialists, and it never will be — the brand's total output was modest, its life span short, and its corporate history tangled up in a family bicycle business and an engine supplier that eventually swallowed it whole. But for anyone tracing the development of overhead-camshaft engineering in France, or looking for the moment French manufacturers experimented seriously with four-cylinder, shaft-drive touring machines, Dollar's decade and a half of production is worth far more study than its obscurity would suggest.
