A while ago there was a company called CycleFX that marketted two interface systems. One was for the Playstation and the other was for the PC. Both systems were pretty sophisticated. They incorporated an interface unit for a trainer's roller to sense wheel speed/acceleration and a front fork-mounted steering input unit. It also accepted HRM and cadence inputs. For those who didn't want to hook up their own bike, they also sold an stationary exercise bike. They also had professional-level training software too. The entire package wasn't all that expensive... around $400 for the basic setup and $600 for the more advanced version. CycleFX went bankrupt and was purchased by Peak Training Systems who I think eventually killed off the GameRider product line.
