I use this for grocery runs on my eBike, and it swallows way more than I expected. The internal zipper pocket keeps my keys and phone from getting buried, and it folds flat against the rack when I'm not hauling anything.
I was surprised how well this tote attaches to the back of my kid's bike—stayed secure even on bumpy paths, and the 60-pound capacity means we can haul groceries easily. Folds flat when not in use, which is perfect for storage.
The 60 lb capacity is genuinely useful for grocery runs, and the internal zipper pocket keeps my keys from sliding around. That said, folding it flat is more fiddly than the listing suggests, and it takes me a couple tries to get it collapsed.
