Because of the vibrations through the handlebars the camera stabilizations gets messed up even after one ride. Mind you, i dont do any offroad, i just have a normal road bike. Google this, since it seems quite common. Also applies to mountain bikes. I've gone through two iphone replacements already. The problem of course is not with the mount, it's with the phone being garbage.
The cover is great, high quality, system works great
It will break the camera on your iphone 11 if mounted on a motorcycle
