BRONDOIT

250 Sport ·1922

Easy to maintain

The first two-wheelers built by Nicolas Brondoit appeared in 1919, in the post-WWI

boom, although this was not Brondoit's first experience of engine manufacture.

Power Unit Pioneer

As early as 1895, the Bayard-Brondoit consortium built four-stroke engines that were intended to be fitted to bicycles and equipped with rudimentary surface carburetors in which the inflammable mixture was liberated by heating the gasoline in the carburetor with a bypass from the exhaust pipe! Around 1902, partnered by one Pocher, Nicolas Brondoit built industrial stationary engines, but WWI brought this venture to an end in 1914.

Simplicity the Object

After WWI, the first motorcycles built by Brondoit had 97cc two-stroke engines that

were mounted in bicycle frames and fitted with clutches but not gearboxes -they were

sold under the name "Ideal-SF." The capacity was soon increased to 130cc, and the first

motorcycle to bear the Brondoit name soon followed in 1922. Its manufacturer wanted to make it simple in the extreme to ensure the greatest ease of maintenance for his clients. This simplicity didn't prevent the Brondoit from proving extremely rapid - it could easily reach 50 mph. From there, it was only a short step to actual competition, and Lempereur, after an initial victory in the 250cc class of the 24 Hours of Vise, also won the 250cc trophy in the 1925 Bol d'Or.
