Abstract: A wheeled knapsack has at least two wheels attached to the base section along the rear edge of the bag portion. The wheels are attached away from the body-contact side of the bag portion such that the wheels avoid any possible contact with any part of the knapsack user's body, when the wheeled knapsack is carried on the user's back. By grabbing and pulling a handle attached to the non-body-contact side of the bag portion, the wheeled knapsack can be pulled on the ground in an inclined position without the shoulder straps touching or dragging on the surface of the ground. In another embodiment of the invention, a wheel assembly panel is mounted to the base section of the knapsack, and at least two wheels are attached to the wheel assembly panel. In an another embodiment, the wheeled knapsack has an axle passage that accommodates an axle with a wheel attached to each end of the axle.
