“Pack & Roll” is a baggage-carrier system for bicycles. Transporting groceries and securing bags on conventional baggage racks is cumbersome: bike panniers have to be mounted in advance, negating the opportunity for spontaneous purchases. “Pack & Roll” provides the solution to this problem. The system is fastened as a fixed element to the baggage rack, its two foldable platforms then providing sufficient load-space. The carried items are secured simply and speedily using the integrated leather straps. When folded up, the system takes up very little space. “Pack & Roll” is a stylish accessory for any city bike.
