Beeway® Bike Saddle Bag, Outdoor Cycling Mountain Bicycle Back Seat Pack Storage Bag - Water Resistant, Colors

I accidentally ordered the light blue by mistake but the bag is so functional and works so well that I don't mind it.It fits nicely under the seat as you can see in the pictures and has enough space to hold a 29er tube, a motow multitool, three tire levers, an ID sleeve and a tire pressure gauge. Im sure I can squeeze one or two CO2 cartridges in there if I wanted to. The fit is really nice and the material looks sturdy. I don't know if the outside is water proof, but the inside is lined kind of the way a lunchbag or cooler would be.

The bag is great.Installation is easy and it doesn't move once it's attached. It looks great and feels very sturdy. It holds a surprising amount. I bought it to keep a multi-tool, a bicycle tool (think large swiss army knife) and a small flashlight in. My plan is to leave these items it the bag full-time. There is plenty of room left over. I added a cigar lighter and two full size cigars to it on my last trip along with a small wallet. The "full-time" items along with the lighter, cigars and wallet took up about 80-85% of the room in the bag (to give you an idea of capacity). There is also a small loop on the bag opening that can been used to hook things on or carry small additional items (I haven't used it yet). The bag sits out of the way, looks great and is extremely functional.So, why only 4 stars? I took a star off (I think I would've only taken half a star if that was an option) because of the way the zipper runs to open the bag. On my bike the bag naturally opens on a slight downward slope. The zipper runs from the bottom left side all the way around to the bottom of the right side which creates a large opening (which is a plus). The only problem with this is that due to the downward slope, once you open the bag everything inside tends to slide out. I think that having two zippers that meet at the top and zip down (one right and one left) would be better. That way you could zip each down 3/4 of the way and nothing would slide out. This is only a minor inconvenience and it is NOT one that would prevent me from purchasing the bag again. I just believe in honest reviews and that was the only "issue" that I have with the bag.It is a great bag that feels like it is going to last me a long time. Well worth it.

Nice price, lots of colors. Fits my mini pump, spare, tools and patch kit with enough room to spare that I can even put my keys and phone in there. (I don't have one of those giant iphones). Amazon Prime shipped it fast and I could've returned it if I didn't like it. But what's not to like. I'll probably buy one of these for each of my kids too.

Does not fit my fat-tire bike because the frame is too wide but that is my fault. It seems made well but smaller than expected,

I bought this for my wife who is a very cautious rider and has never wrecked or done anything risky. Also it appeared to be a perfect fit with her seat, and she did not overload it. This item lasted exactly 2 bike rides before the materials unraveled like cheap tissue paper. I am less than impressed.

Great product! Second one I buy (this time for my racing bike) that holds all essentials needed to replace a flat tire on the road. Thank you!

Great quality. As as advertised. Installs in seconds.

Fits snugly below the seat of my bike and holds enough basics - keys, wallet, phone - for the riding I do. Also easy to remove if I leave the bike locked up somewhere. Still enough room for tire levers and spare tube.
