Claim 8:
9. A vehicle powered by a push input force and a pull input force on a handlebar, the vehicle comprising:
a propulsion mechanism actuated by the push input force and the pull input force on a handlebar, and the propulsion mechanism transmits torque to a drive wheel of the vehicle with the push input force and the pull input force on the handlebar;
the vehicle having a vehicle front and a vehicle rear, a base assembly, and a handle assembly;
the handle assembly includes the handlebar, and the handle assembly positioned substantially parallel to a tube assembly of the vehicle;
the push input force transfers from the handle assembly to the tube assembly, and the pull input force transfers from the handle assembly to the tube assembly;
the tube assembly has a bottom end, and the bottom end of the tube assembly is rigidly fixed to the base assembly;
the base assembly including a mount assembly, the tube assembly rigidly affixed to the mount assembly, and the mount assembly coupled to the crank of a lever arm group by a pin, the pin extends from the crank, and the mount assembly free to pivot about a central longitudinal axis of the pin;
the push input force on the handle assembly generates a forward oscillating motion in a forward direction toward a front of the vehicle with an input force transferred to the crank, and the pull input force on the handle assembly generates a rearward oscillating motion in a rearward direction toward a rear of the vehicle with an input force transferred to the crank;
the push input force rotates the lever arm group in the forward direction, and the pull input force rotates the lever arm group in the rearward direction;
the lever arm group includes a lever link, the lever link having a link front end and a link back end, with the link front end of the lever link coupled to the lever arm;
the oscillating motion of the lever arm group causes the lever link to reciprocate toward the front of the vehicle and to reciprocate toward the rear of the vehicle;
the link back end of the lever link are coupled to a drive pulley at a drive stub;
a clutch belt loops around the drive pulley, the clutch belt loops a first clutch pulley of a first clutch assembly, and the clutch belt loops around a second clutch pulley of a second clutch assembly;
the reciprocation of the lever links by the lever arm group causes the drive pulley to rotationally oscillate, and the drive pulley oscillates the clutch belt in a rotational movement, to rotationally oscillate the first clutch pulley and to rotationally oscillate the second clutch pulley;
as the drive pulley rotates, the first clutch pulley of the first clutch assembly rotates in a first clutch rotational direction and the second clutch pulley of the second clutch assembly rotates in a second clutch rotational direction, with the first clutch rotational direction of the first clutch assembly opposite to the second clutch rotational direction of the second clutch assembly;
as the drive pulley rotates in a drive pulley first rotational direction, the first clutch assembly transmits a drive torque to a drive shaft of a drive shaft assembly, and the second clutch assembly does not transmit the drive torque to the drive shaft when the drive pulley rotates in the first rotational direction;
as the drive pulley rotates in a drive pulley second rotational direction, the second clutch assembly transmits the drive torque to the drive shaft of the drive shaft assembly, and the first clutch assembly does not transmit the drive torque to the drive shaft when the drive pulley rotates in the second rotational direction;
the drive torque upon the drive shaft of the drive shaft assembly rotates a sprocket crank assembly, the sprocket crank assembly having a front sprocket and a rear sprocket, with a rear chain wrapped around the front sprocket and the rear sprocket; and
a rear sprocket adapter connects to a drive wheel of the vehicle, and the drive wheel rotates to propel the vehicle along a road surface.
