Is the M big enough to store my wallet and my iphone 8?

Will easily hold that and surprisingly more. Also kept everything dry in downpour.

When I put my bike on my car bike rack will I need to remove the bag to put the straps over the cross bar?

Yes you will have to remove any bar bags as they will interfere with most racks for mounting. You can always get around this by moving the bag to a different part of the bike but then you have to affix it back when riding for functionality.

I have the iphone 11 pro max, can i use this case to store this phone?

I have the iPhone X and it just fits. Based on what I now of your Phone, it is going to be close, maybe too close. I would look elswhere

Would the medium bag be too large for a child’s mountain bike?

Childs department store bike with buzzliteyear on itn? No. Youth mountain bike? Yes. Should work just fine. Prolly make some kid real happy and turn them into a pro bikepacker. After all thats the key to adventure. Never grow up and always play in your planet!
