Riding a climbing eidolon

[Beowulfe]

I want to get my eidolon which is also a mount the climb evolution. What are the game mechanics for the PC while the eidolon is climbing? How does he keep from falling out of the saddle?

[Worldbuilder]

I don't think there are any. Being ill suited as a mount gives a -5 to ride checks, that may be a reasonable penalty.

Get a Military Saddle.

Dms's call. Just get an exotic military saddle and don't slack on the ride ranks.

Thank you for the image of Obi-Wan on his way to fight General Grievous with his reptilian mount...

If the eidolon has the mount evolution, there isn't a -5 to ride checks, is there?
