West Biking Bike Rear Seat Bag, Double Water Resistant, Zipper, Bicycle Trunk Pannier, 8.6L Capacity Waterproof Backseat Carrier Cargo Pouch with Strap & Rain Cover For Cycling

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

This was delivered about two minutes before I went on a 10 mile ride. I put it on and loaded it up in about 3 minutes. I thought I may have over loaded it, but didn't come close. I've got a full 26 oz Yeti, my bike lock, large battery pack with cables, a micro fiber tool and my bike tool kit, with room to spare. The bag is pretty sturdy too, kind of like a hard shell but soft touch rubber case with a nylon flap with rubber covering the zipper. I'm fairly impressed and I'd reccomend it for anyone in the market for a cargo bag for their bike.

Fits bike perfectly and is very durable I would definitely buy this again, if needed

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.

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!

This is really a nice product. This is perfect for my bike. I can get a lot of stuff in there very well designed looks really cool. Lots of pocket area in the inside. This is what I needed. Thank you very much. Nice work.

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.

Nice bag but zipper(s) only last a year or two.

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.

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 !

Good quality carrier that fit well on the bike. Hold shape well and good construction

Good storage for it's size and quick and easy to fit.

Amazing product. Looks small. Holds alot. Impressed with the structure, the compartments and the amount it holds. Great product. Highly recommend. Have not experienced rain yet with it. Not sure if it is water resistant. Does have a protector that covers the bag
