Anything with an upright enough position should be fine. My Kr8 bakfiets worked well for me (6'5") and my OH (5'9") - it just had a QR on the seatpost for speedy adjustment.
My Yuba spicy curry works great for me at 6'1 and wife at 5'3 with nothing more than a QR seatpost adjust. I thought the tern gsd felt way too short in reach, even with the adjustable stem thing. Upright bikes are very forgiving for sizing.
What other cargo bikes apart from terns are flexible enough to be used by two, very different height, riders?
