Abstract: A human-powered-system utilizing an arm lever assembly and/or a pedal assembly to be adapted to or incorporated into other mechanisms including, but not limited to, wheelchairs and vehicles. The arm lever assembly includes an arm lever that is reciprocated to provide power and rotated left or right to provide steering control. Both assemblies are operatively connected to a converter, utilizing gears and one-way clutches that receives the reciprocal movements of the arm lever and converts them into a unidirectional output, to be utilized in combination or independently. The arm lever is further telescoping and when utilizing a slide mechanism operatively connected to the converter representing a first class lever offers a range of various leverages by correspondingly changing the length of the force and load end when extended and retracted.
