Abstract

Drivetrains for use with a human powered machine, such as bicycles and exercise equipment, including a reciprocating crank coupled to a crank pivot. A lever couples to the crank via a lever pivot positioned on the crank. A lever stop cooperates with a lever guide surface to guide motion of the lever as the lever pivots about the lever pivot. The lever and/or crank are operably coupled to a drive pulley, idler pulley, and/or compound pulley. A drive cable operable couples the lever and/or the crank to the drive pulley, idler pulley, and/or the compound pulley. One or more pulleys couple to the lever's distal ends. The drivetrain includes a wheel hub adapted to receive torque from the crank via a drive pulley.
