BV Strap-On Bike Bag with Reflective Material - Saddle Bag with Seperate Divider for Small Items for All Your Essentials - Bike Pouch with Taillight Hanger for Maximum Safety

This is a wonderful little bag. It is thoughtfully designed, sturdy, and useful. I’ve only used it for short rides of about an hour each, but appreciate the comfort of knowing I am carrying everything I need to fix a flat in a package that is easy to install and remove, tucks securely under my seat, doesn’t wobble around or get in the way of my riding, has reflective tape, and a double zipper for easy access from both sides. Mine is size “large,” which I would call “large enough.” On my Polygon Extrada 7 MTB, it holds an inner tube for 29”x2.25” tire, multi tool that is 3”x1.75”x1”, 3 tire levers, small patch kit, CO2 inflator with cartridge, and 10”x12” microfiber towel. There is about 2 cubic inches to spare, like 2 energy bars. It’s good to know that there is also extra room in the drop down pouch should I need it. Yesterday I had a flat rear tire and I was back on the bike path in about 15 minutes. Was I glad to have everything I needed! I’m also glad I ordered a “large.”

This bag is the perfect size (large). If it is close in price to the medium, opt for the large. It will easily fit an iPhone 15 pro max along with wallet and keys. Looks sturdy, but will update if any quality issues arise. Pros: Inexpensive, good size, well made and designed, reflective material on the rear with a cutout for a reflector. Contoured opening helps fit slightly larger items than a flat one would. Velcro strap for seat post is adequate. Hard plastic insert protects items inside from the seat rails above. Cons: Cheap sewn on nylon zipper pull, single clip design. I wish it had one on each side for more secure mounting and adjustability. TLDR: I'm happy with the price I paid, size, and quality. I would buy this again.

Got the small size and it fits well under my Trek 7.3 hybrid bike, even with the seat in the forward most position, and maybe sticks out half an inch to an inch as in the photo. It is just large and long enough to hold a galaxy s4 smartphone with a case on it, and I could probably get a spare tube, small co2 inflator, and spare cartridge along with a multitool and car keys in there as well to cover basic necessities to help with a flat. The quality of the product seems very good and it seems thick and durable and not cheaply made at all. The slot to put a rear light on does point downward sharply, which is a bit annoying, but it still seems visible, or you can attach it directly underneath the bag on the seat tube as well. I do wish the plastic clip that you loop through the underside of the seat to secure it had the clip on either side of the seat instead of on the top of the bag, as it makes it very difficult to tighten fully and clip so that it sits snugly directly below the seat and not hanging down an inch or so. By the time you shorten the adjustable portion of the clip all the way, you have no room to work to connect it underneath the seat as the bag is in the way. Having the fixed portion of the clip on the side would make this way easier, but once you get adjusted properly its secure, and the velcro strap that goes around the seat tube seems secure as well. Great size for bare necessities that will also fit a modern smartphone and a few other essentials, without being bulky or overkill.

This has been my go-to saddle bag for good quality construction and roomy capacity.

Just a few weeks after purchasing this bag from Amazon, I noticed some loose stitching on the strap that secures the bag to a bike's seat post. No big deal; didn't pay much attention to it. Forward a few more weeks and it now (the seat post strap) is literally hanging by a thread. The bag itself worked out fine for me in terms of its size and limited space as all I put in it were car keys, a tire repair kit and lens cleaner; not even half filled up. That, along with the fact that the bag was properly mounted and hardly ever removed for its under seat mount makes me think the stitching or assembly process in general of this bag is or was lacking. Maybe it's a one-off and not a common problem with most of these but for me, it's proving to be useless. 12/02/2016: Soon after writing the original review, a customer service rep from BV (Ibera) got in contact and at this point, the problem I'd been having with the bag will be taken care of immediately. Quite impressed I must say. Quality customer care is an obvious concern of theirs as I've come to find out; all good. Regarding the bag itself; notwithstanding the problem described previously, it's quite useful. I don't carry much gear at all on my training rides save a tire puncture repair kit, CO2 cartridges, car keys and a few eyeglass lens cleaners. With that rather limited number of items I carry , for me it's the perfect size and solution as its well designed zippered enclosure is easy to access with the bag on-bike and the fact that it mounts under the seat (out of the way), it's easy to forget it's even there. Bottom line, works great for me.

Perfect bike bag. Just what I needed. Great quality, easy installation, really helpful safety features.

Me parece una bolsa de excelente calidad, además tomando en cuenta que la adquirí en una oferta relámpago el precio fue bastante bueno. Compre la tamaño grande y la verdad si es bastante grande, perfecta para una bicicleta de montaña talla L como la mía, en una bicicleta de ruta ya se vería demasiada exagerada, además ni siquiera he tenido necesidad de expandirla ya que su tamaño es mas que suficiente para una camara R29, herramienta básica, parches, snacks y hasta mi teléfono caben a la perfección. El envío de Amazon sin ningún contratiempo y muy bien empacado. Completamente satisfecho con la compra, la recomiendo ampliamente!

I've now got three of these fitted to my various bikes, as they are well made, at a good price, and can easily take all sorts of stuff. As these bags go, they also look pretty good too, with their muted colours not drawing attention, but with reflective strips for a bit of added safety. This latest bag was purchased for my Fat Bike, and it holds two spare fat bike tubes, without needing to unzip the lower expanding part, so these bags can carry a lot of stuff should you need to. These bags seem to be waterproof too. I've pressure washed them to get the worst of the mud off and not found any water ingress so far. I do only use these bags for carrying spare tubes and tyre levers, so I'm not opening and closing them all the time, but they seem well made and the zips so far haven't caused me any bother.

Great piece of kit! (Small Size) Big enough to fit a co2 inflator, spare inner tube, puncture repair kit, tyre leavers, multi-tool and set of allen-keys and have room for your keys and phone. It fits securely, doesn't move about and stays completely out of the way. Nothing more you could ask for.

ＢＶの拡張式サドルバッグに次いで、2つ目の購入となります。 今回のものは、少しコンパクトになるので容量が限られますが、その代わり見た目はスマートで気に入っています。 タイヤレバー、チューブ１本、Ｈｅｘレンチ、財布、スマホ、携帯ポンプを入れていっぱいかな。十分です。

Buon prodotto, non ingombrante, sta bene sotto la sella, provato in varie uscite su sterrato e non si è allentato minimamente
