I wanted to start using my mobile as my bike map and sat nav when I am out doing more touring type riding and on my road bike. I’ve looked around and can’t really find any good water resistant cases with bike mounts or even very many good bike mounts.

The only thing I found that was any good is called a Quad Lock and then buy a life proof copy case on eBay and use them together but that all works out a bit expensive and is a bit Cobbled together. Does anyone have any good cheapish cases and or mobile bike mounts that they would recommend?

Topeak iphone dry bag come with a stem mount.

If your running it with the screen on all the time it’ll kill your battery pretty quick.

I would probably leave it off generally until I got lost though to try and keep battery life
