Advantages of Wheeled Backpack
These backpacks are usually structured like rolling carry-on luggage with backpack straps that can be hidden when you are not wearing a backpack. This allows you to roll it like a suitcase when you don't want to put all the weight on your back, but you can also use it as a backpack when walking on cobbled streets or uneven roads.
Disadvantages of Wheeled Backpack
Wheeled luggage can also be used as a backpack, which comes at a price. It can't be as comfortable as a traditional backpack, because it needs to be more structured. Your back becomes stiffer and flatter, so it feels much faster.The backpack itself will also be heavier because it has wheels, trolley and a stronger frame. In the end, you will get less packaging space, as it will take more time to put the wheels and handles in your bag than traditional rolling carry on luggage.
