Review: Extremely well constructed carry bag... - I wanted a small lightweight, under the saddle carry bag for my bike, to carry the various items needed for repair in the event of a tyre puncture. I have had good luck with Rockbors items in the past, so I thought I'd give this inexpensive under seat bag a try. I was pleasantly surprised at the build quality, coloring, storage space, and ease of mounting this bag offered. It allows me to store a very large number of small items, (more than I expected), with some space left over for a small first aid kit I will be adding later on... The material the bag is constructed of appears tough, and as such, offers protection to the items inside. The inside has been well thought-- there are three separate areas where I can put things. Two areas on both the left and right sides, both bounded by mesh, leaving a central third area. There is a surprising amount of storage available in this versatile little storage bag. The Rockbros logos on each "wing", (see photos), is done in some sort of reflective material so it does make the bike a bit more visible. Mounting was a breeze, I just connected to two "wings", (again see the photos), through the bottom of the seat, then used the included rubber strap to connect the front end to the saddle post. There was a second rubber strap included, but I did not need it. See the photos for an example of just how much stuff that can be put in this bag... Everything laid out fits inside the bag, easly, with a small amount of space left over. I have had no chance to test it in the rain yet, so I can't speak to waterproofing, but based on the build quality, I am not worried. The bag stays put on the bike and is firmly mounted. There really is a ton of room in this thing... I am very happy I decided to purchase this item, I would buy it again after seeing it. For the price I paid, I think it is a steal... I do recommend this bag to anyone looking for an inexpensive under seat bag.
Review: Sturdy, lightweight, well made storage - Bought this for my e-bike. Fits great, holds my phone along with a few bike tools and other small items. Very well made with double zipper that can be opened from either side. Very durable material sturdy but lightweight. My fiend has the same one and loves hers too. Great value for the money.

### ⭐⭐⭐⭐ Decent product
*by M***S on September 3, 2026*

Easy to install and fits the bike very well. It isn't any wider than the bike seat itself so I don't even notice it is there. It's fairly large and I can just barely squeeze in car keys, my phone and my wallet. My only gripe is that the side loops came with a plastic that was sewn into it. I'm not able to completely remove the plastic which is disappointing.
