Mind posting some pictures? I'm a visual guyI put two lengths of 15mm copper water pipe the correct distance apart. (same as vertical distance on the bike mounts.
Fitted to wall with standoff mounts, which ended up correct distance to mount the panniers to the wall as they do to bike.
Could even use the locks. Were Burmot (sp) panniers but assume mount is the same for genuine BMW ones.
It was either mount them on the wall next to the bike or in the corner by the garage door or put them on the shelving. Mounting them on the wall will use "dead space" and free up space on the shelving..
