As far as the oldest fire ship attack, I remember that a Roman Fleet was destroyed by fire ships and even Darius had a problem with the Greeks who attacked his vast armada with fire ships shortly after the Spartans were blocking a pass from the beach.

The IRA used bicycles to quickly move their tactical units from place to place. They referred to them as "Flying Columns"! Ah the Irish, always the ones with a flair for the enemys language.

Digging deep enough, I suppose that some young Irish bomb thrower could have used his bike to deliver a few Mills Grenades to British staff cars. I'm sure they thought of that delivery system and the English passed it on the the Marquis.
