Made in Belgium
from 1901 to 1909 (or possibly 1914)
Sylvain de Jong, born Amsterdam 1868, with his brothers built Mercury bicycles in Antwerp from 1985. He began his own firm, Minerva, in 1899 and began producing motorcycles and voiturettes. His first machine used a Z & L (later Zurcher) engine.
Prior to the Great War, Minerva became quite famous for its range of motorcycles with 1.5hp to 8hp motors. These engines were also supplied to over 100 other manufacturers of motorcycles and motorized bicycles, and were licenced for manufacture in other countries. The factory ceased production of motorcycles in 1909 in favour of high quality cars which competed with the likes of Rolls- Royce and Hispano-Suiza with clients in wealthy and influential circles including royalty and stars of stage and screen.
1904 models had mechanically opened valves and were fitted with Longuemare carburettors. Engines were available in capacities of 254cc, 345cc and 433cc, and in 1905 a 577cc V-twin was added to the range.
The 1907 Minerva was rigid framed (sans front suspension also) with belt drive directly from the crank. In 1909, the final year of production, the factory offered a range of motorcycles from 254cc singles to 855cc V-twins, now fitted with G. & A. carburettors. Brown and Barlow carburettors may have been used some British-built machines, and there is certainly one such in Australia. By this time, the new Bosch ignition was available as an alternative to Eisemann.
In total, some 35,000 Minerva motorcycles were built in the Belgian factory.
The company was declared bankrupt in 1934, and was taken over by Imperia of Belgium which made vehicles during WWII. A revival of the company was attempted in 1953 or 1954 with the production of scooters under licence from MV Agusta, but this failed and the factory went into final liquidation in 1958.
