Abstract: A wheeled luggage is configured to be pushed or pulled using a handle attached to the wheeled luggage. The wheeled luggage has a main luggage body with a plurality of fixed wheels and one or more swingable wheels in front of the plurality of fixed wheels. In one or more embodiments of the invention, one or more swingable wheels in front of the plurality of fixed wheels are easily removable and re-attachable by a user. Furthermore, each swingable wheel has an elongated neck attached or attachable on-demand to a lower front portion of the main luggage body, which creates a higher ground clearance (i.e. backward tilt) in the lower front portion of the wheeled luggage relative to a lower rear portion of the wheeled luggage. This backward tilt enables a user to push the wheeled luggage ergonomically by applying a “pushing” force to the handle.

Abstract: A wheeled luggage is configured to be pushed or pulled using a handle attached to the wheeled luggage. This “push-pull” wheeled luggage has a main luggage body with one or more swingable rear wheels at a rear edge of a lower portion of the main luggage body and one or more fixed front wheels in front of the one or more swingable rear wheels. Each front wheel has an elongated neck attached to a front lower portion of the main luggage body, which creates a backward tilt due to a higher ground clearance in the front lower portion. Each swingable rear wheel is configured to receive a directional force to steer the push-pull wheeled luggage. The backward tilt created by the elongated neck attached to the front lower portion of the main luggage body enables a user to push the push-pull wheeled luggage ergonomically by applying a forward-downward force to the handle.
