Long Torso, Short Legs.

Strengthen your core, so that it's supporting you and you're not putting so much weight on your wrists. The more forward position of the Amira would be a contributing factor. The stem can probably be flip-flopped and angled upward so you're not so aero (unless the shop already did that in the fitting).
And very good gloves.

This is one reason I can't ride the Amira...

This! Strengthen your core, and ease up off your hands. Make sure to relax your shoulders and leave some bend in your elbows.
