GYS were motorcycles produced from 1949 to 1955, in Bournemouth and distributed by the Cairns Cycle firm.
1951 A kit was offered by Cobli of London, to mount the engine under the saddle in order to drive the rear wheel. That year the GYS name was changed to Motomite.
1952 The name changed yet again, this time to Mocyc.
1955 Still known as the Mocyc, the make came to an end.
Mocyc was the name used by the all-alloy GYS cyclemotor from 1952 to 1955.
From 1949 to 1950 it was known as GYS.
In 1951 it was known as Motomite.
