Luggage on wheels makes a lot of sense for carry-on bags, as it allows you to roll the bag in front of you rather than dragging it behind you. It also allows you to maneuver more easily, especially in tight spaces such as an airport corridor. But there are a few issues that travelers should consider before purchasing luggage on wheels.
The first issue is that luggage on wheels tends to be heavier than traditional suitcases and bags with no wheels. This extra weight can cause problems when flying, as it makes the bag harder to hoist into an airplane’s overhead bin. It can also be a problem when carrying the bag on long walks, as it will be difficult to maintain a comfortable pace with such a heavy load.
Another problem with luggage on wheels is that it does not roll well on rough surfaces such as cobblestone streets. A typical luggage wheel diameter is about 8 cm, which means that these wheels are likely to get stuck or obstructed by holes, humps, cracks and other poor surfaces found in many developing countries. Numerous ergonomic studies on carts have shown that larger wheels decrease the push or pull force needed by up to 31% (Konz & Johnson, Citation 2004).
A final issue is that luggage on wheels can be dangerous for people who travel in remote areas. In these environments people walk over very long distances to get their daily work done and often have to carry a heavy load on their backs. It has been suggested that properly designed wheeled luggage could be used as an inexpensive and simple Integrated Management Tool to support these travel needs (Porter, Citation 2008).
