Fog’s Soldiers offers a set of free miniatures rules for Road Cycling, and not incidentally, a line of miniatures to go with it. You don’t need them, though, because you also can download printable rider tokens.

Machinations Steampunk RPG
Machinations is a simple steampunk RPG. From the author’s description:
Welcome to the Eternal City, the home of the Machinations RPG. Take on the role of an Adventurer, an Alchemist, an Artificer or even a deathless Automaton. Band together with others to form a Free Company and then hire yourselves out to perform acts of sabotage, espionage, assassination, extortion, blackmail or plain old robbery. All in a world a short step from our own, where reason has been lost, empires exist to be built and strange technology dominates all walks of life. It is a world of sinister intrigue, awful power, terrible events and dark portents. There is also beer, song and glory
Anticamente Hex Based Ancients
Anticamente is a set of free hex based rules for ancients offered by TB Line Hobby Wargames. It’s a very nicely presented set. The authors write:
The Rules will let you replay the epic battles that took place from Ancient times right up to the early Renaissance period with an “area-based” approach. The use of hexagons will allow you to use three dimensional scenery in complete synergy with the rules without one aspect penalising the other. Anticamente does not pretend to simulate battles; the unknowns are many and modern deductions are often based on hypotheses which, in turn, derive from a few confused and, at worst, contrasting sources. Instead, after some play tests and objective deductions, Anticamente attempts to suggest the reasons why some situation occurred.
