Bike Bag Commuter 17L - Clip-On Bike Rack Bag with Shoulder Strap - Hard Base, Reflective Trim & Taillight Compatible - Bicycle Bag for Daily Use & Commute - PAKRAK ONLY FOR IBERA RACKS

I'm somewhat new to cycling and ended up buying the Ibera PakRak rack for my 700mm hybrid bike - based upon highly rated reviews from Amazon, so I guess I got lucky that I chose this rack.I bought this bag to replace another, much cheaper but highly rated bag I also bought on Amazon. The old bag didn't last 30 days without developing a large hole along a seam, so after doing a bit of research I found that this bag securely clipped into my rack, which was a huge bonus as I never could get the old bag to attach as secure as I like.Let me say this - this bag is HUGE. At first sight I thought it was too big, but once I put my gear back in the bag, went downstairs and clicked this thing on the PakRak in 10 seconds - I was hooked. As my standard kit, I carry a Kryptonite U-Lock with cable, extra inner-tube, CO2 inflator, two CO2 cartridges, my wallet and my keys. I could easily fit a spare water bottle or two, lunch, and much more. I can get probably two days worth of groceries in this. I mean, this thing has tons of room!It does look a bit comically large on the bike, but the more I ride the more I want to ride, and this bike will enable me to do more types of errands as I have more carrying capacity. It was pricey, but it looks as though it's built to last and the fact that the mount/dismount takes seconds and is rock solid is worth the price alone.

This bag is amazing!Ive had it over a year now...It's built very well and still looks new.Has plenty of storage yet compact, looks amazing,and the quick connect works great. It is pricey but I tried several cheap ones before getting this one and It's definitely worth the money just for the quick connect.

I recently got a Kent Dual Drive Tandem for my birthday from my wife. We are planning on using the bike to go on some longer rides on a few different paved bike paths in the area. I wanted to get a nice rack and trunk type bag for the back of the bike to make it easier for us to carry some of the things that we would typically want to take with us, like cell phones, car keys, a few extra drinks, some snacks, and maybe a sweatshirt for my wife.I ended up going with one of the Ibera PakRak compatible racks, and then I got this Quick Release Trunk Bag.The bag is awesome. It's got a solid plastic (looks like carbon fiber) bottom so that if you set it down on the grass or in some water it's not going to actually get the bottom of the bag wet. There's plenty of room inside of it for the types of things that we'll be taking with us on our rides, and quite a few different pockets. I like that it has a handle on the "back" of it so that you can more easily carry it around by hand when it's not on the bike. It also includes a nice shoulder strap so that you could carry it like a messenger or duffel bag if you needed to carry it longer distances.The quick release system on this bag works really well. It is on the bike in a second, and off in two seconds. It fits securely on the rack and I'm not worried at all about it coming loose or falling off while I'm out on the bike.I ended up getting another rack for my mountain bike so that I can carry this bag on that bike as well, I like it so much.It's REALLY nice to be able to have one bag that you can easily move from bike to bike without having to unhook a bunch of straps or tie downs. I will probably end up getting another rack for my road bike, just so that I can use this trunk bag on that bike as well.Overall, I really like this bag, and when coupled with the PakRak racks, it's a really nice system.Highly recommended.

This bag is 100% effective in its intended role. In terms of effectiveness, this is a 5/5. However, I docked 1 star because of some other little issues. I'm not sure whether it's the rack, the bag, or some combination thereof, but attaching and removing the PakRak clip is not perfect. While it holds securely when locked, actually pressing the button feels a little squishy, and it seems nearly impossible to fully engage the lock using downward pressure alone; I typically need to assist the clip with my fingers from below in order to get it to fully lock, which makes it feel a bit cheap, but is not much trouble at all. Prior to understanding this, I was just trying to press down on the bag while holding the button in, and I pinched my thumb which caused a small bruise. I barely noticed, so it's no big deal, but it's just not as elegant as if it "just worked". Compounding this issue is the fact that the rack itself has 2 thin support poles beside where the clip attaches. While this is great for ensuring a secure lock each time, it means there is only 1 exact position where the clip will go down, and when dealing with bike locks and groceries and full hands, it can be difficult to find the exact spot. With a bit of practice, it's not a major issue, but just know that there are probably slightly easier systems out there.Looking at pictures prior to purchasing this bag, I thought the side panniers would be bigger. They really don't feel big at all in practice, and would definitely not interfere with additional side panniers. I also didn't realize that they wouldn't be sewn directly to the hard backing (which doesn't come with any way to secure to the side bars either, not that the side panniers are big enough to warrant that). They're actually attached with Velcro, which means enough weight could compromise the grip and make the side panniers fall right off. The grip is very strong though, so I doubt this will ever happen, but I wouldn't want to load much more than a half gallon of milk in each one. The effective carrying capacity is basically the same as the version with standard side pockets, but with the added benefit of being able to fill longer or oddly shaped items that don't play fit nicely in the main compartment. I suppose the silver lining to having the side panniers attached with Velcro is that you can remove them, freeing up the side pockets similarly to the other version. For that reason, I do recommend this version.The other questionable design element I noticed is that the entire bottom of the bag is a hard shell, while the rack below is an open design. I feel like this adds unnecessary weight to the bag itself. It does give it a nice solid shape, but that could have been accomplished with much lighter cardboard or plastic inserts. It also depraves the Ibera racks of a neat feature of the Topeak MTX racks, which is that they effectively work as a mud guard for bikes without them. My bike does not have mud guards installed, so that was something I found neat about the MTX system. Instead, with PakRak, any mud or water kicked up by the tires will end up on the hard bottom of the relatively heavy bag, which I need to carry indoors. Again, not a big issue, but enough to make it less than a 5-star product.Finally, there's the price. While this is competitively priced with similar locking systems from other brands and manufacturers (which is why I ended up choosing this over the Topeak MTX), there's still a fair bit of markup over generic Velcro-strapped bags and standard racks. I could have saved a fair bit of money buying the cheapest rack available and a comparable bag with Velcro straps, but I really valued the stability of the locking mechanism. I realize a lot of things go into determining price, and ultimately, a specialized solution for a niche market will likely end up costing more than a generic bag which could be used for anything, but it's still something a consumer such as myself must take into account when shopping.One thing I worried about was size, moreso for the rack than the bag. I was afraid the bag would be pressed up against the back of my saddle. However, it fits exactly how I want it to, very close but not touching. It's ideal. I have a 2017 Giant Escape 1 city bike, frame size small, and there's no interference whatsoever. The rack also fits perfectly, with just enough bar length to reach the eyelets on the seat stay. Overall, I'm extremely happy and satisfied with this purchase, despite its imperfections, and I highly recommend it for anyone looking to carry a light load of groceries with maximum comfort and stability. At a slightly lower price, this would have been a definite 5/5, but it's worth exploring more generic alternatives if you're on a budget.
