رف خلفي لسرير Pvy

The luggage rack can hold light weights, but why are the brackets further forward on the frame not used, but only 2 screws per side right at the bottom and close together on the rear wheel axle.

It needs an extra fixation point, being the better at the front.
I will create it as this way it is not trusty to carry anything with more than 1kg.

No instructions delivered on how to mount. Additionally the holes do not allign well which requires a lot of effort and force as the mounting screw reaches the hole under a slight angle.

The rack is only rated 15kg, which makes sense as the mounting screw are too close to each other, meaning it cannot handle a rotational momentum.
