1. A vehicle powered by a rider's arm, comprising:
a propulsion mechanism actuated by the rider's arm engaging a handlebar;
the vehicle having a front and a rear, a base assembly, a frame assembly, a tube assembly, and a handle assembly;
the handle assembly including the handlebar, and the handle assembly connected to and positioned substantially parallel to the tube assembly of the vehicle;
a push input force from the rider's arm and a pull input force from the rider's arm transfers from the handle assembly to the tube assembly;
the base assembly including a mount assembly, with the tube assembly rigidly fixed to the mount assembly of the base assembly;
a drive shaft assembly extended from the frame assembly, with the drive shaft assembly including a drive shaft;
a lever arm group attached to the frame assembly, with the lever arm group including a lever crank;
the mount assembly coupled to the lever crank of the lever arm group by a pin, the pin extends from the lever crank, and the mount assembly free to pivot about a central longitudinal axis of the pin;
a push of the rider's arm on the handle assembly generates a forward oscillating motion in a forward direction toward the front of the vehicle with a push input force transferred to the lever crank, and a pull of the rider's arm on the handle assembly generates a rearward oscillating motion in a rearward direction toward the rear of the vehicle with a pull input force transferred to the lever 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;
a lever link having a front link end and a back link end, and the front link end is coupled to the lever arm of the lever arm group;
the forward oscillating motion of the lever arm group causes the lever link to reciprocate toward the front of the vehicle, and the rearward oscillating motion of the lever arm group causes the lever links to reciprocate toward the rear of the vehicle;
the back link end of the lever link is 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 link 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.
