@bitboxer At the first glance quadlock ticks of all your boxes. The question is what sort of cycling do you do?
I managed to have a it rattling so much that the phone popped out of the case. But I was driving with my adventure bike over cobbles at 30km/h and the case was leveled for the best aerodynamics.
For normal cycling with my citybike quadlock works fine for me.
I want to mount an iPhone to my bike, but need these criteria matched:
* Easy to use with my case or easy to swap for the biking case * Stable and trustworthy grip on the device * Some form of anti vibration because some iPhone lenses hate that vibration 😅.
