Jesmo was a motorcycle produced from 1910 to 1915, by a Mr Capes of Motordom, Spring Bank, Hull.
Mr Capes had been an agent for the JES engine unit and, hoping to improve on this, he used a Chater-Lea frame for his machine. The result of this was that he produced a motorcycle rather than a cycle fitted with an engine. The make was somewhat short-lived.
