ROCKBROSBike Bag Bicycle Frame Bag Bike Triangle Storage Bag Bike Accessories Pouch Cycling Pack for MTB Road Bicycle Accessories

I’m very happy with this purchase. The bag feels like it’s made well. Storage is as I expected. Wasn’t surprised or disappointed in its capacity. It was easy to install and fit my Ozark Trail gravel bike well. I did have to cut the Velcro straps to length, but I’m glad they gave me plenty of length to work with.

I spent ages looking for the perfect bike bag. I needed something to carry the essentials, and nothing more. I needed it to disappear when I didn’t need it. This is that. It fits my wallet, keys, and a power bank and cord comfortably, but isn’t unnecessarily spacious. It fastens securely to the bike without wobbling. The materials and zippers are very sturdy, and I have no worries about anything falling out. It’s lightweight and very skinny, and hardly protrudes beyond the width of the bike frame, so it’s as out-of-the-way as possible. Essentially it’s reliable, there when you need it, and gone when you don’t, which is everything you can ask of a good bike bag.

This is a great bag. Fits nice and secure under the top tube and It's narrow enough so my legs don't hit it. This bag is a great size for your phone, ID, and key fob. It's a nice design. This works perfectly for my neds

This case is good quality and holds enough items for me, tire tube and electric air pump plus small tools. I installed it upside down so I can carry bike on easily.It looks better than under seat bag, but I can use both if needed

Seems like a well-made bag. The material looks like some kind of woven nylon. Stitching seems adequate. Velcro straps or long enough to provide different mounting options. The zipper operates smoothly without sticking or binding. It opens from front to back and the flap opening is at the top and opens in such a way that you can access things while you're riding the bike and the flap will keep things from falling out. There's also a small mesh divider so you can put your more important items behind the mesh. It's big enough to hold a very large cell phone, wallet, keys, a multi-tool, and even one or two small power bars. Perfect for shorter rides in urban areas. If you need to load up a spare tube and a pump along with a phone and keys, you may run into difficulty as the bag is not long enough for my pump. If you use a cartridge inflator you may be able to get away with it.

Works well! Able to put my wallet, phone, car keys and my AirPod case!!

The bag is solid, looks cool. but I wish it was a little bigger.You can fit your wallet, phone, keys, airpods, and maybe a protein bar but that’s about it.

Great addition to my TREK bike. I do not need to store my wallet, phone and car keys in a pocket, this storage bag packs well. Fits on bike as shown- nice and secure. Out of the way from knees and thighs.
