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

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.

I like the bag. It could be a little larger, but it fits on the bike, doesn't get in the way and holds a spare tire, pump and tools to change a tire. Not much else. I gave a five star rating, but I think it would be better if the bag was slightly larger. Also, bag easily can be placed on bike. All you need to do is wrap the 3 velcro straps.

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

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.

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.

Perfect for a pistol!!

Nice bag, fits nicely in the bike frame. Plenty of room for my bike tool, holds my truck keys, cell phone and other stuff while I ride. This bag was a good choice

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

Its an essential product to keep the keys, wallet, mobile phone etc... Need to check the frame size before you order as the bag will get squeezed due to bottle holder.

Very nice bag. Well made. Lots of room. Looks good

Fit my bike frame perfectly. Padded on inside and sturdy outside so cell or whatever you carry will be protected from bumpy trails to accidental bike drop. Also waterproof is nice. Quality product is nice to see compared to most of cheap through away products of todays world.

Works well. Lots of room. Easy to use.
