It has the extra space I needed to keep my security cable and lock. Well built and functional.

Even large size is very compact - fits nicely tucked under bike seat. Strap fill secure but clasp is plastic so hopefully it will hold up. Love the back and will get a lot of use out of it. It’s a bit smaller than I expected, but can cram a lot in there. Does NOT fit a water bottle - I wish it would. My only other comment would be that my bike tail light doesn’t attach well to the loop style. I wish they had some sort of built-in reflector at least. This bag will completely block your tail light if attached to the Bike post

We have used the large BV saddle bag as a tandem stoker bag for several years with excellent results. We recently added a new tandem to our collection and bought a second BV bag for our new bike.These bags fit well (check the dimensions on your bike), the seat post Velcro strap works, the saddle strap can easily be wrapped over the stoker stem on top, and we add a length of double-sided Velcro to the fabric loop underneath the bag to wrap around the stoker's top tube. It is easy to install. The bag opens from the top facing the stoker, and is durable and spacious. There's plenty of room for a spare inner tube and a power bank to run the stoker's iPhone. Recommended for this application.

Great size with expandability. Plenty of room for lock or light jacket

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.”

It is small but expandable. It easily holds an extra bike tube, tire irons, patch kit, keys, cell phone and garage door opener without opening the expansion. It opens in a way that all of your stuff does not fall out when you open it. It is made of durable material and should hold up well!

The bag itself is fine.The issue is the velcro strap that attaches the bag to the seat post.The strap is too long and wraps all the around the seat post.Hence the velcro can not stick to the fuzzy part of the strap.I will have to manually cut off the velcro, cut off some of the strap to shorten it, and then sew the velcro part back on to make this work.

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!

Lサイズですが程よい大きさでサドル下に収まる大きさです。開口部は縦横10cm程度で、2つ折りの札入れが縦または横にして収納できる大きさです。奥行きは17cmほどで先細りです。下部のチャックを開けると手前の底面部分のみ5cmほど広がります。バンク修理機材や財布、小銭入れを入れるには問題ない大きさですね。ブランド品に比べ布地がやや薄めですが、型崩れ防止の板が上下面と蓋の部分に入っており造りは悪くありません。側面には反射材があり、夜間の視認性も考慮されています。蓋にはクリップ式の反射板やテールライトを取り付け可能なバンドが付いています。安価ですがしっかりした造りで使い勝手も良いサドルバッグです。

Después de haberme enfadado, muchísimo con esta bolsa, pensaba que era una basura, tengo que rectificar y decir que ahora si, es perfecta.El fallo que cometemos muchos es no saberla colocar en el sillín de la bici, lo explico a continuación.Situamos la bolsa debajo del sillín, y los don enganches van desde el interior , pasando por las guías metálicas del sillín hacia el exterior, damos la vuelta por toda la alforja y la cerramos. Queda perfecta y no se mueve una vez ajustada.Llevo con ella casi dos meses, es perfecta, enorme, me entran dos cámaras de 29, desmontables, parches, herramienta multifunción, el móvil de 5,5 , DNI, Tarjeta sanitaria, dinero, llaves, adaptador válvula y sobra sitio, todo ello sin agrandarla. Tiene un detalle , un llavero para poner las llaves y una red para recogerlas.Se me pasaba , viene con reflectante muy visible por la noche.Aguanta el agua, y mucha, barro, descensos duros, viajes en el coche etc..Recomiendo la compra de este producto

I'm not surprised that this cycle seat bag has such high reviews (and top seller in category if I'm not mistaken). The bag comes in three sizes, for this review I will only discuss the Large size.Good:-Construction is solid. No obvious defects or points of potential failure.-Ample room. I was able to fit (without using expansion):-Multitool-CO2 cartridge and adapter-spare tube-two tire levers-latex gloves with patch kit and link-2 cliff bars-a concealed carry (Sig Sauer P238).-There was space for my car key and my phone as well, but that would be about the limit without expanding it.-Internal hook and mesh netting for keys. Extra layer of security.-Simple attachment mechanism.-Thin profile -- does not stick out wider than even a narrow seat.Bad:-Seat tube strap is FAR too long to give a tight fit. You will have to cut and resew if you wish to have it snugly attached to seat post.-Has a horizontal strap on back to attach light. Most lights attach horizontally because they would normally go around the seat tube. Consequently, I had to attach my light sideways. An additional vertical strap just above the horizontal strap would resolve this problem.-Bag does sway side to side, but this is unavoidable. During riding I do not think it will affect anything. Only way to avoid is to have an internal frame so you can tighten the seat strap completely. Without frame, the bag will just collapse in on itself. During rides, it may be a good idea to cinch down the strap fully and let the bag compress onto the contents to minimize swaying.Bottom line: The bag is great and I would absolutely recommend it. To the manufacturer, I would suggest incorporating my two recommendations (seat tube strap length & vertical strap in back) for future iterations of this great product. Until the manufacturer applies the recommendations, a rider can always take the bag to a sew shop and have the modifications done for just a few dollars.I've included a couple pictures: A side profile with ruler (~6.5" deep) and a perspective angle.

Cercavo una borsa sottosella sufficientemente capiente in cui riporre tutti gli oggetti indispensabili (smontacopertoni, spray antiforatura, camera d'aria, mini pompa, ecc e rimane ancora spazio) e facendo qualche ricerca mi sono imbattuto in questo modello della BV. In effetti lo immaginavo un po più grande, e al momento dell'ordine ero indeciso tra questo e la misura M. Pensavo che la taglia L fosse troppo voluminosa, invece sono soddisfatto di aver acquistato la misura più grande (non sporge dal sellino ed e particolarmente capiente) e ne consiglio sicuramente l'acquisto anche in virtù del buon rapporto qualità /prezzo!!

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.
