## Customer Reviews

### ⭐⭐⭐⭐⭐ Well-designed trunk bag
*by  on Reviewed in the United States July 28, 2025*

I bought this for one of my ebikes and it's a very well-made and useful trunk bag. It attaches securely to the rear rack and does fit under the seat. The two side zip pockets are long enough for a phone or wallet, while the roomy inside can hold tools, a light jacket, small first aid kit and more. At the end is a Velcro pocket just right for keys or something small. And there's more: the top is designed with stretch laces to hold a water bottle, plus there's a mesh slip pocket on top as well. If out for the day on the bike, I could stash a DSLR camera, water, emergency tool kit and everything I need. The outside material sheds rain. The bag is lightweight but sturdy, attractive and all the zippers work well. Great purchase and I may order another.

### ⭐⭐⭐⭐⭐ Great bike rack bag
*by  on Reviewed in the United States April 17, 2026*

This bag fits perfectly on my rack. It's waterproof because I just got caught in a storm and not one drop went inside. I feel this bag is worth twice the money it sells for. The material used is top grade and the workmanship is perfect. The bag is roomy and has three pockets on the outside and a large interior. One thing I would like to see is four loops (one at each corner)so it can be zip tie it to my rack which would make it harder to steal. Overall, this is a excellent bag and I highly recommend it.

### ⭐⭐⭐⭐⭐ Attractive, Well-Made and Functional Rear rack cycling bag
*by  on Reviewed in the United States March 15, 2025*

This is an attractive and well-made rear-rack bike storage bag. It easily attaches to the rear rack with four adjustable Velcro straps. The tapered front end of the bag fits nicely under the rear of the bike seat. The main compartment is relatively spacious; the two side zipper pockets are useful, inter alia, for holding a cellphone, keys and garage door opener. The four zippers are rugged. The nylon material is thick enough to hold its shape well. A carrying strap is supplied but I haven't used it, nor have I tested claims of waterproofing, although the recessed zippers will at minimum be water resistant. I am expecting the bag to work well for my commute.
