Manufactured by Enrique Sanchis, Courbevoie-Hauts de Seine, 1905 to 1912
Presented at the Paris Salon of 1906, the Sanchis Triauto was a tadpole-style tricycle powered by a 4.5 hp engine concealed beneath the armchair-like single seat. He later built voiturettes.
The Sanchis was marketed in Great Britain by Leon Pierron as the Mass.
