Color: Bike Bag with Tail Light
The overall look is superb. Much better than the soft saddle bags I previously had. Zippers work great. Fits quite a variety of tools, glasses, etc. I opted for the optional $4 rear light. It firmly attaches quite well to the bag. It's adequate and can be seen by motorists.

The bag is very nice and well constructed. The light seems to have a difficult time holding a charge. I would definitely recommend this item if the light is not important to you.

Happy with the product. It looks exactly how I expected and fits right for my MTB. Light works fine and last many hours blinking.

Color: Bike Bag with Tail Light
I love this bag! In particular, I like the light, which deserves more focus than the bag itself. It's a medium-size, hard-shell case that mounts under your seat. Easy to install without tools in 5 minutes. Clips on and off instantly once the bracket is mounted, so you can carry your little bike-purse inside with you. It's big enough for any cell phone, wallet, keys, and a (very small) lunch. There's a shelf inside to keep things separate, and a tiny mesh pocket on the door for keys or benjamins. There's a zipper to expand volume a tiny bit -- such a small increase as to seem almost pointless. The zippers are waterproof and good quality. The light is the coolest - You can leave it on all the time, and it will light up automatically when the bike moves, and turns off 30 seconds after all motion stops. When you brake, it glows bright red. There is no installation/integration with your brakes -- it just detects the deceleration of the bike and lights up. The light easily twists off for recharging from a USB-port. Nicely, it is not obvious to an observer that it is removable, to reduce theft. It clips directly to the bag, and it comes with separate mounts for independent seat or post mounting without the bag. I mounted my light to my cargo rack. All in all I give it five stars. For the thirty-dollar price, it is an excellent value.

Color: Bike Bag with Tail Light
This review is actually for two items, a taillight and a saddle bag. It just happens that they come in the same package and are integrated so the light mounts on the bag. The challenge here is that I have different views on the items but can only give one set of stars for both of them. First the light. I like the light. It is really why I got this product. It has some smart functions to sense ambient light and movement of the bike. In smart sensing modes, it will turn off in daylight and also turn off to save battery if stationary for more than 30 seconds. It will also sense motion and become bright when it detects deceleration to serve as a brake light. There are also 2 manual modes, a flashing and a constant mode. The light can go up to 300 lumens, which is good for a taillight in most conditions. It has a USB-C charging port, is made of aluminum, and weather resistant. The 300mAh battery has claimed run times of 8 to 36 hours. I think in reality we can expect about half of that time. It has a Garmin-style mount and includes an extra seat post mount. It is a very compact light and quite impressive output for its size. Next the saddle bag. It is a large bag with a lot of room. There is a divider inside that cuts the space into upper and lower halves, with the lower area slight larger. Personally, I don't like wide bags because they tend to rub my bib shorts. In this case it is for a family member who prefers a wider, padded saddle, so the width isn't an issue. Additionally, the bike has wider tires, so the spare tube needs the extra room provided by the bag. The bag has a hard shell and covered zippers that are claimed to be waterproof. The mounting is via a clip on the top of the bag that clamps on to the saddle rails, and a Velcro strap on the front securing to the seat post. I like that it has clamps to the rails instead of straps to keep the bag from swaying too much. The rear of the bag opens down and has a small compartment inside to hold money or keys and also provide access to the Garmin mount for the light. Lastly, there is another zipper along the length of the bag, from front to back, to expand it for more storage space. Personally, I would prefer if the bag tapered toward to front for more clearance or have the ability to extend farther behind the saddle. I would give it 4 stars if reviewing it only.

Color: Bike Bag with Tail Light
I got this behind-the-seat seat bag for my youngest son who is very much into fitness, biking, running, weightlifting, etc. I think he's going to like this very much. They're labeling this as a bag, but it seems much more like, what I would call, a case than a bag. Anyway... This seems like a very nice case for carrying any items you might want/need to carry with you on your biking ventures, with a somewhat limited space constraint in mind, of course. There are two sections for storage in the compartment, a smaller upper slot, with a larger compartment on the bottom, there's also a small mesh pocket on the inside of the cover. The front side has a zipper so that it can be opened up about an inch or so for a little bit of an expansion of the storage space. The taillight is removable for easy charging via USB-C cable connection The whole case can be removed with the simple press of a button on the catch that holds the case onto your bike, (once you've attached the mounting bracket to the underside rear of the seat), which strikes me as a bit of a design flaw, (the main reason for my deduction of one star). If you were to stop at a convenience store, for example, to run in and grab something, someone could very easily take your case with the simple press of a button and make off with whatever the contents of the case might be, not to mention the loss of the case itself. Another small flaw in this case, (in my humble opinion), is how difficult it is to maneuver the zipper around the rounded corners of this case. While they are made so that they'll be waterproof I don't know if that's the reason for the difficulty or if it's simply poor quality zippers. The point is, though, the zippers, on the back of the case especially, where the corners are tighter, can be quite difficult to operate, at least, they are on the one I received anyway. Overall, the quality of this case seems quite good to me, in spite of some minor flaws that I see, and well worth the current price of $38, ($36 with the currently available coupon), and a 4 star rating.

Color: Bike Bag with Tail Light
This seat bag with auto brake sensing light is all that and then some! The bag is molded, not flimsy and holds its shape. Nice heavy duty waterproof zippers. On the side are a pair of zippers that allow you expand the bag slightly, similar to how a carry-on luggage works. Made by Rockbye and sold by YBLNTEK? I think. Either way, I love this bag. Mounting Comes with a plastic clamp style seat bracket that you attach the bag to. The Bag slides onto the bracket and locks in, has a lever to release it and a stabilizing Velcro strap for your seat post. You may need to move your seat mounting position back slightly to expose enough rail to attach the bag bracket. You can angle it a bit or keep it level. If you have a suspension seat post the bag kisses the post a bit where the Velcro strap attaches and when the seat compresses the zipper pulls on the expansion portion bump/rub, I just open the expansion zippers about a half inch open on both sides, solved. Interior is sectioned off with a mesh shelf so there's a top and bottom so to speak . There's also expansion waterproof zippers that run along the side to the front of the bag, unzip them and the bag expands a bit larger if you need that little extra room. It may be helpful to have your bag tilted slightly nose downward so that if your bag is stuffed full the contents won't spill out. or just be careful when you open it if you mount this horizontally level. Brake light Comes with an auto sensing brake light that is made by Rockbye. On the back of the bag is a brake light mount area (Garmin twist in style) built into the back cover. If you want to you can install just the brake light to your seat or to your seat post with the supplied mount or bracket. The light works very well, easy to use, 4 modes and engaged with a simple push of the button in the center of the light. Good stuff Nice Roomy bag that sits out of my way Comes with auto sensing brake light that works very well. 3 possible mounting locations for the auto sensing brake light. Waterproof zippers Bag can expand slightly like a carry-on Great looking bag

Color: Bike Bag with Tail Light
Had a bicycle that needed a seat bag. The good: bag is well constructed with good fit and finish, visible stitch is even with no loose threads, rigid structure holds a good amount of stuff (easily holds 6.1" smartphone, car keys, patch kit, tire irons, one spare road tube), zippers appear to be waterproof/water resistant, easy to install, easy to mount/dismount from seat once set up using toggle, nifty tail light attachment built-in, rechargeable tail light is a nice bonus (haven't used it yet). The neutral: zippers are stiff (but all waterproof zippers are that way in my experience) and expansion zipper volume only adds space in the front portion of the bag. This is my first rigid seat bag and I'm pretty impressed with the value, especially given the current price of name brand soft seat bags. Can't speak to durability yet given have only used it for a handful of rides - happy to have it.
