Well, the main thing is the low gear (35-50 gear inches approximately), and pretty much everyone plays with a freewheel now. Apart from that it's personal preference, head tube angles, fork rake, dual brake levers, etc. Old mountain bikes are good for beginners, or trick/track frames.
Alex who posted above tried playing on his fixed wheel bike, with a road gear, bullhorns and a front brake. I don't think it was particularly fun, too much concentration going into staying upright instead of playing the game.
