Abstract: A pivoting crank arm apparatus that increases the user's torque. The pivoting of the crank arms further allows the user to quickly move the pedals out of the dead zones at the top dead center and bottom dead center of the crank cycle. This prevents the user from stalling in these dead zones while climbing hills and other high torque or slow pedal speed situations.
The pivoting crank arm apparatus is comprised of a set of crank arms attached by a spindle. Each crank arm is further comprised of a pivot arm with a pedal. The pivot arm being pivotally attached to the crank arm and configured to allow for the pivoting action of the present invention.

Abstract: A bike pedal assembly uses a pawl, a gear and a torque spring to enable a rider to store and release torque energy while pedaling a bike. The pawl and gear are connected to a nut on an axle, which is connected to a crank arm of the bike. Being connected to the gear and a foot pedal, the torque spring stores torsional energy when one end is stationary and the other rotates with the foot pedal during half of the crank arm resolution, while releases torsional energy during the second half to the crank arm. Thus, the pedal assembly, which can be efficiently installed on each of the foot pedals of the bike, allows the rider to store and utilize additional torque energy and provides a more efficient means of storing torque energy than the conventional system.
