Abstract
A device for sensing a bicycle pedaling torque input includes: a housing; a bearing defining a rotational axis; a bearing support member that positions the bearing with respect to the housing, the bearing support member including one or more beams; an output member configured to be coupled to a chain ring, the output member being coupled to an inner race of the bearing to enable the output member to rotate with respect to the housing about the rotational axis; a spindle configured to be coupled to a bicycle pedal crank, the spindle functionally coupled to the output member to enable a rider pedaling force applied to the spindle to cause rotation of the output member; and one or more strain gauges, each of the one or more strain gauges being coupled a beam of the bearing support member.
