ZIMFANQI Bike Trunk Bag 8L Bicycle Rack Rear Carrier Bag Water Resistant Bike Commuter Bag Bike Rear Seat Cargo Bag Cycling Luggage Bag with Rain Cover

Decent quality overall. Attaching straps are very secure and allow for multiple fitments.

Solid construction good zipper's good for carrying few small items

This bike bag was so nice, someone else liked it too, and took it.It was stylish, had room for my stuff, set up easily, and was working fine for a month. And then it was gone.It's not the fault of the bag. It is a statement of the world we live in.

Fits a drink bottle in length could be handy to have a carry handle

It works great, and it’s a decent value for the money, but it is perpetually squished at the rear. No matter how I try to stand the sides up or how I distribute the tools I keep inside, the back half is always sagging.It came with a free seat cover so you don’t have to use a grocery bag when parking your bike in the rain, so I’ve got that going for me, which is nice.
