The invention is an improved lever drive arrangement for human powered machines. Independent levers are connected directly to a primary drive arrangement positioned behind the rider comprised of one-way clutch/s connected to a common shaft connected to a sprocket that drives by chain a series of two reductions called a secondary drive arrangement and a tertiary drive arrangement prior to engaging the final drive element. The positioning of the primary drive arrangement behind the rider better enables upright riding by a person and better enables increases in lever length thereby increasing mechanical advantage is possible for producing greater torque to drive larger or multiple reductions. The independent lever arrangement allows a rider to deviate from the traditional opposing circular or up and down cadence of the rider's limbs making possible a variety of limb pumping movements by one or more limbs.
