This bag is the perfect size for storing small things like your phone, wallet, keys, etc while you are biking. It's also very vibrant and the material seems thick and sturdy. It attaches to three points and is adjustable, so it should be very versatile for all sorts of bikes

My review is based on a month plus of use over 100 miles on 4-5 rides. I try not to review anything unless it has been a min of one month and/or 5 uses depending on how its used, lets face it most things look good right out of the box you want to know how its holding up after the return window closed.Box/Bag opening and initial thoughts-comes in a simple clear bag, taped shut, inside of the tube bag are two air pillows. Has a small circular tag which was not attached to anything that has a logo, some inspection info in Chinese, and a warranty card that give you a 15 or 30 day warranty-which is not much. No Install instructions-which for me took about 5 min to figure out the clips unclip for install-I was honestly starting to wonder there for a bit. Bag looks good all stitching is even, zipper moves well-not silky smooth but decent, colors really pop. I especially like that the interior is orange as it makes it easier to find things inside-often lose track of small things inside black bags. I was hoping from the description that said “Side Mesh Pocket Design” there was also a mesh pocked in the main compartment that I could put my phone in, but I am assuming they are referring to the two exterior side pockets which will hold food bars, small gel packs well-small disappointment.Install/Use - I am putting this on my multi use Rail Trail, Gravel, and light mountain biking (no jumps over 2ft, no drops over 3ft-I am getting old) Superfly hard tail. I had a few different bags and have yet to find the one. I liked the colors on this and my large top tube should be about the same size as the bag. Install was fairly easy, just getting the right spacing on the clips and pulling the cordage threw, chances are if you’re an outdoor enthusiast you dealt with this setup before. I wish the bag had a double zipper, makes life easier. I could barley fit my Pixel 8 (5.9” wide regular not pro) it just fits I have to push it all the way forward, with that I put in my keys, small wallet, and mini ear buds case and it was full. I wish there was a key hook or a mesh pocket as mentioned earlier, when I open the bag I have to re-arrange the items or push my phone forward to get it closed again. I was not brave enough to try and open it while riding. My food bar of choice fits well in the side pouches, they are pretty deep so I pulled it to the front for easier access, other wise you would not even know its in there and I don’t want to have to dig around, but should fit many sizes and keep them secure. Overall has worked well zipper has stayed put during rides, and bag has been rock solid on the tube both on the car rack and ridding. Its not a bag your gonna be able to open and pull you phone out easily while ridding unless that is the only thing in there, listing says phone up to 6.7 wide but I don’t see that happening.Final thoughts-I am sure you noticed I got this from Vine, because I write these awesome long reviews and take pics, as I too read reviews and use them to help me make decisions-hopefully you found my review helpful-now would I pay my hard earned side hustle, social monetization or 9 to 5er money for it-It’s a toss up, still not the one for me, Great colors, rock solid attachment, but small back end barley fits my phone. It really does tapper down in the back which can be problematic with stuff and reduces storage dramatically. Most other bags I have don’t do it to this degree. I consider value and what your spending in all my reviews and I have to give it 4 stars for Meets MY Expectations for price paid. At time or review it was $18 which is cheaper then most on Amazon. I was drawn in by the colors-so many are black, and the mounting system-which has worked well. More storage space inside and a pocket or key ring would be my upgrades,I will update if I encounter any problems, Adventure is out there.
