Having had problems with other similar designs, I built this wall mount from the ground up to be more secure with heavier bikes or, in my case, on drywall.
For each wall mount you need to print two pins which you screw securely into the wall. I used the drywall screws shown in the last picture. You need to mount them at a distance of 36.5mm from each other. After that, the bracket slides in securely and satisfyingly.
