A frame for carrying a luggage item, the frame comprising a wheel assembly and means to releasably attach a luggage item to the frame, the frame and the luggage item thus forming a luggage assembly, the wheel assembly comprising at least one front wheel (142, 142', 148) and comprising rear wheels (144, 144', 146, 146') comprising a first rear wheel (144, 144') and a second rear wheel (146, 146'), said wheels are moveable between a folded position and an unfolded position, wherein, - a surface of the wheel assembly defines a bottom flank of the luggage assembly facing, in use, the ground when the luggage assembly is placed on the ground with said wheels (142', 144', 146') in the unfolded position, the bottom flank has a push direction edge and an opposite pull direction edge, the push direction edge is facing in a forward direction when, in use, the luggage assembly is pushed by a user, the frame further defining a rear side being a surface of the luggage assembly coupled to the bottom flank at the pull direction edge, - the folded position of said wheels (142, 144, 146, 148) is within the luggage assembly, - the unfolded position of the at least one front wheel (142, 142', 148) is completely at a side of the bottom flank that faces away from the luggage item when attached to the frame and is a position closer to the push direction edge than to the pull direction edge, - the unfolded position of the rear wheels (144', 146') is completely at a side of the frame at the pull direction edge that is facing away from the luggage item, - when the luggage assembly touches the ground with said wheels (142', 144', 146') in the unfolded position and when the luggage item is homogeneously loaded and attached to the frame, the luggage item has a tilted position with respect to a line perpendicular to the ground in which the rear side tilts towards the ground and has a projected center of gravity (Pg1p, Pg2p) of the luggage item in between the rear wheels (144', 146') and the at least one front wheel, the projected center of gravity (Pg1p, Pg2p) of the luggage item is a perpendicular projection of a center of gravity (Pg1, Pg2) of the luggage item on the ground. - a surface of the wheel assembly defines a bottom flank of the luggage assembly facing, in use, the ground when the luggage assembly is placed on the ground with said wheels (142', 144', 146') in the unfolded position, the bottom flank has a push direction edge and an opposite pull direction edge, the push direction edge is facing in a forward direction when, in use, the luggage assembly is pushed by a user, the frame further defining a rear side being a surface of the luggage assembly coupled to the bottom flank at the pull direction edge, - the folded position of said wheels (142, 144, 146, 148) is within the luggage assembly, - the unfolded position of the at least one front wheel (142, 142', 148) is completely at a side of the bottom flank that faces away from the luggage item when attached to the frame and is a position closer to the push direction edge than to the pull direction edge, - the unfolded position of the rear wheels (144', 146') is completely at a side of the frame at the pull direction edge that is facing away from the luggage item, - when the luggage assembly touches the ground with said wheels (142', 144', 146') in the unfolded position and when the luggage item is homogeneously loaded and attached to the frame, the luggage item has a tilted position with respect to a line perpendicular to the ground in which the rear side tilts towards the ground and has a projected center of gravity (Pg1p, Pg2p) of the luggage item in between the rear wheels (144', 146') and the at least one front wheel, the projected center of gravity (Pg1p, Pg2p) of the luggage item is a perpendicular projection of a center of gravity (Pg1, Pg2) of the luggage item on the ground.
