Collapsible carts are disclosed. The collapsible carts include a frame, a load bearing member and a wheel assembly. The wheel assembly includes a housing with a horizontal pin channel and an elongated diagonal channel. The horizontal pin channel may be adapted to guide a pin to transpose horizontally along the horizontal pin channel while rotatably coupling a leg member of the frame to a horizontal section of the load bearing member. The elongated diagonal channel may be adapted to guide the horizontal section of the load bearing member to pivot around a pin axis and move from a horizontal plane in the open condition to a generally vertical plane in the closed condition. The movement of the horizontal section along the elongated diagonal channel actuates the housing to rotate around the generally vertical axis.
