Bike Seat Bag - Bicycle Saddle Bag Under Seat Cycling Accessories Storage Pouch Wedge Pack for Mountain & Road Bike - Black

I really like this under seat bag. It is just the right size to keep a few repair tools some snack bars and my keys while riding without being bulky.The only somewhat funky thing about it is the zipper feels to me like it is too long. Sounds weird but when you fully unzip it, the entire rear of the bag folds down and small items can easily fall out.

The main use is for holding my cell phone on casual rides. The size and durability of this bike bag meets this need. As you can see in the pictures, a Pixel 7a (2.87 inches wide) is wider than the narrow end of the bike bag. As a result, the phone fits inside diagonally. There is still room for keys, a wallet and granola bars. Given the materials used and the quality of construction, I see this bag lasting several years for me.

I was looking for something small that would fit a phone. A small snack would fit in as well. I like the reflective tape and overall a nice little bag.

Does the job okay for a drink or light materials, but I don't know if I'd trust putting my phone in it. Connections are a bit flimsy and the stitching is less-than-perfect. If you just want to bring a water bottle on your casual bike, this should do fine, but I wouldn't recommend this for avid cyclers.

This bag is pretty sturdy and fits nicely under the seat. The zipper feels solid, and while you never know how long they'll last, this one glides smoothly. I didn’t notice any issues with the stitching either. I don’t really use it for ride storage; instead, I keep two tubes, a patch kit, a CO2 inflator, three tire levers, and a multitool in there. It fits everything perfectly, and I could probably squeeze in my car keys, some cash, and cards too. For me, it’s all about having a repair kit handy on the bike, and it does that job really well.The only downside I’ve found is the loop on the back. It points almost straight down, so if you were hoping to attach a rear light, it wouldn’t work out. Just something to keep in mind!

Sturdy fabric, good zippers, tiny, light, adjustable, cheap. Winner, especially for the price.Also has a tiny elastic pouch inside for keys or whatever- love that.I'll report back after more use as to how well it stays in place and if it moves around at all, but so far I love it.

Attaches easily and securely under many bike seats - just make sure you have the loops under the chair accessible. I couldn't attach it onto my wife's bike but it fit on mine because the seats are slightly different. Waterproof, durable, and a perfect size for a set of spare inner tubes and small tools. Fill it with your emergency supplies and forget it's there until you need it!

I ordered this little seat bag just to have somewhere to stash my snacks and keys while I'm on the move. It serves that purpose beautifully. It's long and thin, which is exactly the right shape for protein bars, sunglasses etc. At the same time, it's not too big and bulky to detract from the overall look of my Giant Anyroad. A+
