Yes it can. Turn the knob and it shifts if the bike is in motion or not.
Despite its weight (which is arguably insignificant on a cargo bike), this may be the go. I'm liking what I'm reading, but one question to Val: in the three times you asked the Nuvinci folks about exceeding their stated limits, did you specifically prompt regarding durability issues? They might very well elide that discussion unless explicitly prompted...

In my experience, I've on several occasions brought home 400 pounds of potting soil and or fertilizer on my Xtracycle. It's 7 miles from the nursery to my home, the largest hill is about a half a mile of 7%-8% grade, and between the electric assist and me standing on the cranks that's a lot of juice going through the hub. It's held up without sign of wear.
