Great product. Looks great on my mountain bike. Will attach to any rack

Love the roomy bag. Holds all essentials for a ride. Well made and good value for the $$

Love the size, the small side panniers, extra bottle holder and all the well made components. Love the rain cover, too. The attachment straps didn't quite line up perfectly with my Trek ebike rack, but I think it will be stable as I bike more with it. One suggestion is that it needs the velcro straps to adjust to narrower racks...I had to wrap the strap around to make it shorter to stick.

This well-made bag has come in very handy. I usually ride my bike to a local restaurant for lunch. I put ice packs, drinks, and storage containers in this for the trip over and fill up the storage containers with leftovers for the trip back. On our last trip, we stopped at the grocery store for a few items (steaks, heavy cream, 2 packs of frozen raspberries to name a few) and this bag held everything we needed.

This bag is well made and sturdy. There is a flap to cover the zipper to help keep contents dry. A rain cover and carry strap are included. It holds a bottle with maximum diameter of 3 inches. I have a 24 ounce Takeya bottle pictured in the holder. I had to scooch the bag forward on my rack, so it hangs over the front about half an inch or so. Otherwise, the bottle holder rested on the raised "tail" and pushed the bottle out. The velcro straps for anchoring are generously sized. My rack is shaped more like a trapezoid than a rectangle, and there was no issue with holding either end securely. I'm underwhelmed with the panniers. They are small, but I was tired of asking Alexa to translate centimeters to inches for me while shopping for bags, so I just hoped for the best. They'll do in a pinch for small extra items, but don't plan on using them to carry anything over 8 inches tall or wide. The zipper opens starting halfway down the pannier. I would have preferred it to zip across the top only, giving the option to carry an item sticking out the top slightly.

Great add to my bike. Straps make sure it attaches securely and is relatively easy to tighten and adjust. Perfect amount of storage for my afternoon ride with my daughter on our snack run.

Great quality bike bag.
Reviewed in the United States on May 14, 2026 by sky
The bag itself is nice and large - but it attaches very poorly to any of my bike racks. It sits loose and eventually leans to one side and sits crooked. Looks really sloppy and no matter what I’ve tried.. I cannot get it to sit center, tight without leaning to one side. So I bought a different brand bag.. the jfal and that is 10x better and sits super tight and clean. Such a shame.. this bag itself is great, just bad Velcro strap design.
