## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice bag for ebike
*by G***G on April 19, 2025*

Nice size, fits well on my ebike.

### ⭐⭐⭐⭐ Great Bag - Water Bottle Issue.
*by C***A on March 22, 2025*

Perfect size bag for long distance rides to throw a bunch of items in it. One major flaw - you cannot use two water bottles (on seat post and down tube). Only 1 water bottle will fit which is an issue unless you wish to make frequent water stops.

### ⭐⭐⭐⭐⭐ The quality is exceptional.
*by W***� on April 27, 2025*

I’m super thrilled with this product. I have found that everything I have purchased from Rockbros is the best. It was a perfect fit.
