A manual hand-rim assembly (26) positioned proximate the first drive wheel (22) which is mounted for rotation relative to the first drive wheel (22) about a common wheel axis (24). An elongated drive axle member (30) is coupled between the hand-rim assembly (26) and the second drive wheel (23) which is substantially axially aligned to rotate about the common wheel axis (24). The axle member (30) includes a first latching mechanism (31) on one end thereof which is releasably coupled to the hand-rim assembly (26).
