Abstract: An exercise device includes a stationary support structure and a power input arrangement supported by the support structure, which are configured such that the user applies input power to the exercise device at the power input arrangement. A rotary member is supported by the support structure, and a power sensing is driven into rotation by input power applied by the user. Input power applied by the user is transferred through the power sensing arrangement to impart rotation to the rotary member. The rotary member is in the form of a rotary resistance-providing member, which is rotatably supported on the support structure by the power sensing arrangement. In one form, the power sensing arrangement is driven into rotation via a chain drive system interposed between the power input arrangement and the rotary power sensing arrangement.

Abstract: A cable-type actuator assembly for a cycling exerciser having a cable operated resistance adjustment mechanism and a cable operated braking system. The actuator assembly includes a caliper actuation cable operably connected to a caliper that acts on a wheel of the cycling exerciser. An actuator is mounted to the frame of the exerciser, and retains the distal ends of a brake cable and a resistance adjustment cable and is connected to a forward end of the caliper actuation cable. Actuation of either the brake cable or resistance adjustment cable moves the actuator, thereby actuating the caliper actuation cable.
