Blackburn Bike Seat Bag with Tail Light Strap

Perfect size to keep a spare tube, patch kit and a couple of tools. Well stitched, velcro straps to mount it, and a strap to mount a rear reflector or flashing tail light.

Bag is very nice quality with quality zipper and stitching. Attaches well under seat and stays in place. Overall great bag!

The quality was more than I expected for the price. Size was perfect and attached under the seat well.

Fits perfectly. Size is just right. Zippers hold as does the Velcro straps.

Perfect bike under seat saddle bag. I've got a Trek X Caliber 8 and this little bag fits nicely under the seat and does not stick out behind the seat edge or look weirdly oversized while riding. It fits a 29" bike tube, a bike multi-tool, a couple tire levers, a CO2 inflator nozzle and cartridge, and my mini-first aid kit of bandages and ointment; there does remain just enough room that I may place a patch kit in there as well. It is a snug fit for all of these but that just means there is nothing rattling, shaking, or moving around as I hit the single track trails; exactly how it should be. Very happy with this bag function and it is even better that it came in under $10.

Great for the mike and use it a lot. Nice fit and quiet handy to have. Blackburn is a good product athe bike seat bag with the tail light strap is cool and convenient. My husband wants one and my friend is getting one as well. Can't beat the price and the gear.

This was smaller than I thought it would be, barely big enough for some small items. But it hooked right up to my bike, I poured water on it and it passed the waterproof test, and the construction seems very durable, no cheap stitching or zippers. I think it will hold up well and for a long time.

Just what I wanted

Looking forward to trying this nifty little bag on my bike once the weather gets nice again. It's small, so it won't get in the way and hinder riding ability. It will come in handy if I need to carry my keys or some money. I wish it were just a tad bigger so that my iPhone 11 could fit as well. If you have a smaller size phone, it might be able to fit.

This black, nylon bike bag by Blackburn is made really well and has several great features. I like the zippered closure to help keep things inside the bag from slipping out, so that's a big plus. It installs easily with with a wraparound, heavy duty Velcro strap, which makes it adjustable and easy to remove. It fits nicely underneath the seat, so it doesn't hinder movement while riding your bike. Another feature is that a light reflector can also be attached to the back of the bag to provide extra safety while riding. This bag is suitable for a cellphone or set of keys, but not much more, as it is a smaller size bag, about the size of an adult hand. I've used other bike bags that were larger in length and width, so for me, this was tiny, but still useful. I think it's best suited for a kids/teen bike, but again, we'll made, great features and useful for a few small, personal items.
