A front wheel (16) and a front wheel mount (44) are included, the front wheel mount (44) being pivotally attached to the frame (14) by a lower frame pivot (40). The golf bag cart (10) is movable from an extended configuration (12) to a collapsed configuration (13), such that the rear wheels (18, 20) pivot about the mid-frame pivots (68) to move towards the front wheel (14). The front wheel (14) and the wheel mount (44) pivot about the lower frame pivot (40) so that the front wheel (16) moves towards the rear wheels (18, 20), as the golf bag cart (10) is being collapsed.
