In 1876, Dalifol built a very innovative, steam-powered tram in collaboration with Am�d�e Boll�e p�re (1844�1917). The company owner died in 1888 and his 21-year-old son took over the management and experimented with automobiles and motorcycles. In 1894 the company built a steam motorcycle with the word Volta prominent on the the engine.
There is a suggestion that the machine was based on a license from Heinrich and Wolfgang Hildebrand, one of which was sold to Paris in 1893.
Bourdache has an informative article on this motorcycle.
