    Used this mostly as a tool bag. Helped me to get some of the weight to the center of the bike on a tour and continues to be good to have the tools on day to day riding for when things break. Plenty of space for every tool, and room enough for extra chain and straps.
    It did keep water out but you do have to remember to zip it all the way. If I had to store anything valuable in there, I’d wrap it in another bag loosely to have full confidence but that’s if I was going to be out in extreme conditions.
    I’m surprised when gear holds up and doesn’t eventually fall apart from use and conditions. This one has so far made it through without getting torn or punctured and the straps and zippers are totally intact. It has a sort of rubbery linerbon the inside walls which has not degenerated and has kept any oil from soaking into the bag itself.
    It’s likely to last many more years.

    I like it it’s the perfect accessory for my e-bike to carry the essential tools that you need in a pinch. The bag is water resistant and scotch garden so it doesn’t get too dirty I would recommend that bag it’s good stuff.

    The bag seemed to be good quality. I wanted to carry a spare eBike battery in it, but it did not fit. The battery is 17 inches long and since the product description says it is longer, I assumed it would work. However the zipped opening is on the side not on top or bottom, and it does not open all the way. So, the bag ended up being 2-3 inches short to get the battery inside it. I guess if you want to put a few small things inside, as long as they are not too long or two wide to fit through the unzipped opening, it would be a good enough product, but certainly not if you have one long items like an eBike battery or other such items. They won’t fit. The velcro to secure it to the bike seems alright, but for a heavier item I would put additional zipped tie or velcro strap.

    Really well made and good space. Will hold multiple water bottles, small tablet, tools, small poncho, etc. light weight and well designed. The split divider allows you to easily separate snacks and water from electronics and tools.

    Preface: this isn’t REI-type outfitter rugged and durable and pretty, and maybe it doesn’t have to be. Getting gear off your person and onto the bike is its own reward and this no-frills bag does the trick.

    For tooling around town, bike trails, maybe some light bikepacking, it serves well and is simple to install and use and remove. And the $25-ish pricetag beats what could easily cost $80+ for a fancier bag.

    Pros: Aforementioned price. Ease of use. Quick transfer of items you would normally keep in pockets or fanny packs etc. into a more convenient and comfortable place. It’s water-resistant, but it hasn’t seen a deluge so I can’t say anything further on that. But it’s doing its job and I’d recommend it for anyone but a serious cross-country tourist.

    Cons: the zippers are lower quality than you’d find on pricier bags, and assumedly should have a shorter lifespan than those. The Velcro straps that hold this on aren’t stitched on, the loops the pass through aren’t welded or stitched. It’s low-cost for a reason and I don’t expect to see it last forever.

    Fits large 56cm frame, able to fit 2 bottles underneath. Not possible to access water bottles while riding, may have to modify mounts to get a little more clearance. Otherwise very happy with the quality/value. Recommended.

    Good, roomy bag. I was concerned that my knees would hit it, but as long as I don’t overfill it, they don’t. It would be nice if they had a way to keep it from expanding too much on the sides.
