This is the Honourable Jesse Macintosh, a former penny-farthing policeman, whose reputation was perilously injured whilst performing his lawful duties.  Now a Scotland Yard trouble shooter, he’s been recruited for an exceedingly secret government mission to ride Street Hawker – an all-cobbled surfaces attack bicycle designed to fight urbane criminality, capable of incredible speeds up to thirty miles an hour… immense firepower… and a really loud speaking horn. Only one man, Her Imperial Majesty The Queen-Empress Victoria’s confidant, Lord Axminster (the prominant inventor, industrialist and engineer Norman Tuttle-Herringbone-Smyth), knows the Honourable Jesse Macintosh’s true identity. The Man… The Machine… Street Hawker.

Miniatures shouldn’t be a problem with Eureka’s Pax Limpopo range including a variety of eminently suitable figures.  I’ve not settled on a rule set yet suggestions in the comments would be greatly appreciated.
