GREAT BAG, PERFECT FOR ME!
I bought this to replace a 25 yo Trek bag that was always bigger than I needed, and, though still completely intact, was begnning to sag a bit on the sides. I decided to try a hardshell, because of the clean, streamlined appearance, and after looking at several, chose this one, wisely, I think. The deciding factor for me was the fact this one was higher in the front, tapering to a lower profile in the back, whereas the others were just the opposite. It seems to me not only a more logical shape, functionally, but also a more aerodynamic, and attractive look. The new bag also afforded the opportunity to clear out many things I've been carrying for years, but have never used, transferring only those items that have potential utility. It's just the right size for me, seems of good construction, straps on tightly, and includes quality zippers. I really like it, and look forward to many years of service.

Glad I Bought It
This well made bag is light weight and easy to install behind the bike seat. There's plenty of room for storage and the zipper works well and seals the bag from the elements. The bag replaced an older heavy basket that came with the bike and looks a lot better. I chose this bag because of the looks, and price; comparing it to other similar items that were $100 or more. Glad I bought it!

A Good Place to Store Your Gear
We recently bought e-bikes, and now we can ride much farther than we used to. With those longer rides and more complex bikes comes the need to haul more stuff. The bikes came with rear racks, but no bag. After looking at 900 bike bags, I decided to go with this one and I'm pretty happy with it. It holds my cable lock, tools, a small medical kit, and an extra water bottle. I could put an extra bike battery in here too if needed. If we happened to shop or pick something up while on a ride, I have extra room. This bag feels sturdy and looks nice. Some bags kind of look saggy or deflated when they aren't full, but with the rigid sides, this one holds it's shape. The only thing I don't love about it is that you have to undo long velcro straps to remove it. So if I were to go in a bar/restaurant/etc. and wanted to take this with me, it would require some fiddling. My old "analog" bike has a Topeak MTX(?) which has a track and latch system, where you just push a release button and slide it out, which I prefer. I would recommend this for anyone who doesn't typically remove their bag often as it is durable and feels like it will last a long time.

Extremely well made
I’ve been searching for this type of bag for a long time. The West Biking Rear bag is just the right size, not too big but large enough to carry a day’s riding essentials plus outer elastic tie down and bottle holder. It stays put on the rack and doesn’t slide around at all. Great bag 5 stars

Great addition to my E-bike
Holds well, is sturdy, is spacious, and has utility. I can fit like 5+ drinks in it, plus my DJI mic, charger, camera, and power bank. It holds in place going 50mph and on bumps, coming off curbs, etc. versatile I'd say. It's also really stylish, I get compliments often about this bike and I'm sure this adds to it. Just matches really well I think. The price isn't bad on this either. It is easy to put on with it's straps, like I said, stays in place. Easy to remove and can even be used as a travel bad or gym bag with it's straps and handle.

Decent bag
Decent bag, somewhat water resistant. Large enough to hold my extra Aventon Battery. Its a bit of a pain to take on and off, when it wears out I replace it with one with a easier connection system.

Excellent Cargo Case
Compared to other Bike carrier bags that I've had, this one beats them all. It is strong with reinforced plastic sides, and fastens securely on the carry rack. It has a zipped top, and has plenty of room inside. Perfect !

its a great bag
This purchase fits my bike rack perfectly. Eactly what I was looking for. its narrow enough to reduce wind drag when biking yet tall enough to carry rain gear, phone, pump, other tools, food and other stuff for a long distance ride. The zipper could be more robust yet being careful will prevent any problems. The hard sides are great in that the bag holds its shape when empty. it doesnt have too many extra pockets that would add to its bulk yet not serve a practical purpose. Im also able to attach a taillight to the unused water bottle pouch at the back of the bag.Im happy I bought it.
