It makes sense.

I mean, someone on a bicycle is faster than someone running, right?

And a horse running is faster than a man running, am I correct?

Therefore a horse on a bicycle would be extremely fast. I've been discussing it with a friend, and the main problem I can find is designing some sort of bicycle contraption for them. They'd use four legs to propel themselves, rather than two...how would that work? Can anyone give me some sort of working idea of what a horse bicycle would be like?

I have a suspicion this sports going to take off like wildfire.
