Those bikes look pretty indistinguishable if it weren't for the brand decal.
Anyone can ride with a pannier, or top bag, or bar bag, or saddlebag, or fanny pack, or messenger bag, or backpack, if they want to. A backpack is easy for starters because you probably already have one. I don't like the sweat either but I often do it anyhow because it's easy to switch bikes.
