Abstract
A cycle crank assembly includes a crank spindle and a drivetrain connector configured to translate rotation of the crank spindle into rotation of a wheel. A crank arm includes a pedal interface configured to receive a pedal spindle of a cycle pedal. A slip connection is configured to allow the crank arm to rotate about the crank spindle. A resiliently deformable member is connected to the crank spindle and the crank arm proximate to the pedal interface. The resiliently deformable member translates rotation of the crank arm into rotation of the crank spindle. The resiliently deformable member deforms under load to store pedal energy provided by a rider to the cycle pedal and returns at least a portion of the pedal energy when not under load in a direction of the rotation.
