Abstract: A vehicle power transfer system and method, and vehicle using the same. The vehicle power transfer system including a differential unit coupled to a half axle, and an electric motor for supplying torque to propel a vehicle. The electric motor is collinear with the differential unit and the half axle.

Abstract: A sulky includes a frame and a first and second wheel supports. The first wheel support extends along a first axis and is rotatably coupled to the frame about the first axis. The second wheel support extends along a second axis and is rotatably coupled to the frame about the second axis. First and second pedals are operatively coupled to the frame and to the first and second wheel supports, respectively. The first and second pedals are moveable relative to the frame for rotating the first wheel support about the first axis and for rotating the second wheel support about the second axis. A linkage operatively couples the first and second wheel supports for transferring movement of one of the first and second pedals to both of the first and second wheel supports to rotate the first and second wheel supports in unison respectively about the first and second axes.

Abstract: There is disclosed in one aspect, a self-aligning sulky with independently pivotable wheels which may be pivoted through a full 360 degree rotation. The pivotable wheels provide a sulky that provides less rolling resistance and greater resistance to tipping. In another aspect, the racing sulky is provided with steering means to alter the orientation of at least one of said wheels relative to the frame of said sulky. In yet another aspect, a suspension means for the wheels is provided.
