Travel Suitcase To-go by YANG DESIGN for Tumi

Nice. But the way you present it makes it more of an advertisement for your design firm. Which is not permitted.- this forum is for the discussion of design,not advertising. You would have known this if you had read the Discussion Boards Posting Standards. The link is at the bottom of my signature.

Show us how you developed the product; sketches, study models, prototypes, and so on.

Im curious as to how much extra space/weight the single wheel scooter aspect takes up.

Somethings I immediately see. Reduced room in luggage.
Weight - how much would this weigh unloaded? Most Airlines have a weight requirement.
Check in only? Size makes it seem like no way you could carry it on, much less lift it over your head.

Have any more details on this idea?
