I know most suitcase these days have four wheels. However, when you pull it on the road, in most cases, you are only using two wheels. It makes pulling difficult, especially when you have many things laid on top of your suitcase. Balance Wheel Carrier try to solve this problem by providing 3 wheels, which keeps the balance of the suitcase and eases wobbling with shock absorbers. The fifth wheel is integrated at the lower back of the suitcase, which you can easily pop it in/out with you foot. Allowing 360 degree rotation, this fifth wheel will make dragging suitcases a piece of cake.
You want to go on a trip with your baby. However, how can you take your luggage and baby carriage at once? Will you give up your trip? Ride ON is an innovative concept offers you a versatile baby carriage that adapts to being a suitcase, when not being used for the baby. Essentially it hosts a dedicated seating area for the baby, while the rest of the bag can be used for your travel stuff. The idea is pretty cool but the design is quite fashionable. But I am not sure is the seat is comfortable enough for baby to sit for long time. Terrific work! [source]
