Spark Motors of 46 Upper Thames Street, London, EC.
Spark was a motorcycle produced between 1903 and 1904
This machine was a typical primitive that was built in small numbers. It combined a 2hp engine and a surface carburetter with a heavy-duty bicycle frame and any extra fittings that were necessary. It made many claims about its reliability and did run in the 1,000-mile Trial.
Typically primitive, it had gone from the market by the time of the 1905 slump.
