Which bike carrier can I attach the bag to?

On almost everyone: The fastening system for clicking in adapts to the diameter of your luggage rack. From 5 to 18 millimeters in diameter, the side pocket will therefore hold on any pole. You should only measure once in the case of particularly thick luggage racks, e-bikes with batteries and folding bikes.
