Joyca 1950
Manufactured by Jover i Carreras of Sant Victòria Street Maó, Menorca. Their main products were engines for fishing boats. During the 1950s they produced an inverted two-stroke auxiliary bicycle engine which attached to the rear wheel.
An example has been displayed at the Bassella Motorcycle Museum.
Menorca is well off the Mediterranean coast of Spain, almost half-way to Sardinia. The Colomet was built on the neighbouring island of Majorca (Mallorca).
