An exercise device for active or passive therapeutic exercise of human lower extremities provides a portable base structure supporting a housing that journals a laterally similar adjustable pedal crank rotatably carrying pedals on its outer arms. Motor and drive mechanism carried by the housing power the pedal crank for rotary motion and a brake structure selectively restrains its motion. The housing is adjustably positionable relative the base about three perpendicular intersecting axes and each of the laterally opposed pedal crank arms are compound elements interconnected by adjustment structures allowing positioning of each of three elements forming each pedal crank arm about two mutually perpendicularly axes. Pedal structures, adjustable for foot size, are rotatably mounted on the opposed lateral elements of the pedal crank. Each pedal structure mounts a pedal plate for universally adjustable motion relative to the pedal crank to adjust the plane of contact of a user's foot therewith.
