1. A pulley assembly for engaging an endless member of a segmented pulley transmission, the pulley assembly comprising:
a first pulley rotatable about an axis of rotation and having an outer peripheral surface for engaging the endless member;
a second pulley configured to concentrically surround the first pulley and having an outer peripheral surface for engaging the endless member, the second pulley comprising a set of second pulley segments that are independently movable between an engaged region and a disengaged region; and
at least one transition segment set comprising one or more transition segments that are independently movable between the engaged region and the disengaged region to transition the endless member between the first pulley and the second pulley, the at least one transition segment set defining at least one transition surface for engaging and transitioning the endless member between the first pulley and the second pulley.
