Great little bag
Iâm very happy with this purchase. The bag feels like itâs made well. Storage is as I expected. Wasnât 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 Iâm glad they gave me plenty of length to work with.

Exactly what I needed
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 didnât need it. This is that. It fits my wallet, keys, and a power bank and cord comfortably, but isnât 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. Itâs lightweight and very skinny, and hardly protrudes beyond the width of the bike frame, so itâs as out-of-the-way as possible. Essentially itâs reliable, there when you need it, and gone when you donât, which is everything you can ask of a good bike bag.

Perfect Size for my needs.
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

Plenty of room for cell phone and car keys.
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.

Plenty of room and aesthetic
This has been a very good bike accessory for me. I like the fact that it tucks away under the crossbar and is unobtrusive. It has plenty of room for my cell phone, wallet, tire repair kit and more! I am very happy with this product.

Surprisingly well made bad
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.

Meh, you get what you pay for
It’s an average little bag for an average price. It doesn’t look the best, but it works.

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.
LJM –
Very nice bag. Well made. Lots of room. Looks good
jr –
the bag itself is well built and easy to use. lots of space and fits perfectly. The only draw back is that you will have a hard time pulling out your water bottle from underneath it. could have built it a little less deep and on the longer side. overall good product and does the job as described.side note – you can fit a lot of stuff in it for the size
Phil –
Bag works great for small items. I can get my wallet, small battery pack and multi tool for my bike in it. My only problem is I can use the back strap to tie it because my water bottle is in the way. Would be nice if there was another strap at the front to keep it from sliding back all the time. Great size and nice looking bag!

This bag is well-made and durable, but it doesn’t hold much: a cellphone, some tissues, and a set of keys.
