Bags for Radwagon?
I recently picked up a used Radwagon (2018) and am looking to start outfitting it. I'm interested in bags for hauling groceries - does anyone have experience with Rad Power's Ballard bags or a different brand? When I read the description of the Ballard bags, I see they are only 6" deep, which sounds awfully narrow to fit a standard paper/reusable grocery bag. Maybe this is a normal size for a cargo-bike bag? I'm aware of the Xtracycle X2/X3 bags, but wonder how well they fit on the Radwagon frame.
I'm not interested in normal sized panniers - I'd really like something the length of the deck (or close to it).
Thanks in advance!
