- Reviewed in the United States on May 20, 2025I've had bike bag and never use it. This one is easy to fasten, large enough for folded tarp and book, great stretch cords on top to hold my lunch bag, and even a small pocket on the back when I remove my sunglasses! Only concern is how long the zipper will last. And velcro at front is a bit short, but it still worked.
- Reviewed in the United States on May 19, 2025A well designed rack bag. Roomy sturdy and stable .easy to setup and remove. Not much for security as standard but can be done. All straps and zippers are strong. Overall another good product from this company. Well pleased.
- Reviewed in the United States on March 23, 2025Pretty good bag but the Velcro bottom could be difficult to wrap around baskets/bask rack but once you find a good way to wrap it, it’s a good bag… wish it was a bit bigger maybe… looks good on my Lectric One since the bike is kinda small.
- Reviewed in the United States on April 24, 2025I love this bag! There are many compartments and it holds a lot. I use it to hold drinks, snacks, repair kit, phone, small hand towel, money, lock, etc! The velcro straps are easy to attach and detach from my bike rack and it stays secure. I do not use the water bottle holder on the back as it's not wide enough for anything but a standard disposable water bottle, so that feature is useless for me.
- Reviewed in the United States on May 23, 2025Awesome fit for my needs.
- Reviewed in the United States on April 27, 2025Very good quality bag fast and easy to attach and remove love the cup holder
- Reviewed in the United States on January 16, 2025I just recently purchased a new E bike that has a space provided to attach a bike bag. One of the drawbacks to going bike riding. Is you either have to wear a backpack or be very limited in what you take with you. This bag is very well-made in high-quality. Surprisingly, it holds a lot of things. It was extremely easy to attach to my bike using the Velcro straps and I found that it also came with a shoulder strap so if I decided to go off the bike and go hiking on foot I could use it as a shoulder bag. Couldn't be more pleased. Definitely a worthwhile purchase.
- Reviewed in the United States on March 17, 2025Took me a while to figure out how to attach it to my wife’s e-bike but once I did it’s working perfectly.
