I personally bought an extra main battery for mine. Amusingly, the cover for the battery (the green plastic shell that matches the frame) wasn't available until like May, so I got just the bare battery. Works fine, looks a little goofy. The two batteries gets me 60-65 miles of hilly gravel riding in eco, which covers my riding nicely. I still plan on grabbing an extender when they are available, just because the main+extender probably covers a lot of my loops, and then I don't need to haul the second main battery or stop and swap, but its not pressing. Shop charged me $500 US for the second main battery.
I don't have an auto mode on mine (US, not Canadian). I don't think I'd use it if it did, I like setting the percentage of assist to be constant.
Still really happy with the bike, aside from the anemic battery. Its a wonderful ride on the gravel roads of Loudoun. It feels very much like my non-e-gravel bike, which is exactly what I wanted.
