Emerald
Emerald was a motorcycle produced circa 1903.
In common with many other bicycle dealers of the early days, this company added a motorised version to their range. The name appeared on a machine that had a sturdy cycle loop frame fitted with a 1.75hp or 2.75hp engine and a two-speed gear in a simple transmission.
