COTOUXKER Bike Frame Bag, Mountain Bike Bag for Road and Mountain Bikes Lightweight Cycling Storage Bags (Small black)

Yes it worked really well I would recommend it

Not too big but just big enough to stuff a phone, charger, and wallet in, me personally I used it to hold my e-bike controller wires

I recently made an upgrade to my mountain bike, adding a product that allows me to turn it into a quasi e-bike. Living near hilly streets in Southern California, this enhancement has been especially useful. However, with the additional motor and modifications, I found that typical storage spots on my bike, like behind the saddle and above the rear wheel, were now occupied or unsuitable for carrying gear. Since I can't mount a rack over my rear wheel or hang items from my bike seat, I needed a solution for storing small tools and essentials while riding.Enter the COTOUXKER Bike Frame Bag, a lightweight, compact cycling storage bag that fits neatly onto the frame of my bike. At a very affordable price point, this bag provides a simple, yet effective solution for carrying small items I would otherwise stash under my seat. It doesn’t interfere with the e-bike motor’s operation, and it’s positioned in such a way that I can still access my water bottle, which hangs below it.The bag attaches securely with Velcro straps—two on top to bear the weight and one on the side to keep the bag in position, though it doesn’t bear much of the weight. This setup works surprisingly well. The bag’s triangular shape might not be ideal for squarer items, but it makes good use of the limited space available. I can easily store a small tool set, snacks, keys, wallet, and even a few dollars. It’s great for short rides when I need a few essentials but don’t want to carry extra bulk.While the bag is functional and convenient, it’s not fully watertight, so I’m cautious in inclement weather. I’m glad that it’s easy to remove and bring indoors to dry off if needed. The construction is solid for the price, though I don’t expect it to hold up well under continuous exposure to harsh UV rays or extended use. The fabric seems durable, but only time will tell how it holds up to regular sun exposure.One small drawback is the logo on the bag. It’s not mentioned in the product photos, and it’s a different brand than the seller name. While it’s not a major issue for me, the branding stands out a bit more than I anticipated.Overall, this bag serves its purpose perfectly for short rides or as a way to carry small items without cluttering up my bike’s other storage areas. For the price, it's a solid product that provides good value, and I would recommend it for anyone needing simple, lightweight bike storage. Four stars because of the branding confusion and minor concerns about its durability, but it’s still a great option for daily use.

Great bags. Inexpensive and easy to use.

good holds my tools

Using as a tool bag for a motorcycle & holding up well. In this use case it is receiving far more stress than what would be likely for its traditional use. I would recommend for either application.

This little frame bag is about as basic as a plain bagel. Functional, but not exactly thrilling. It straps onto your bike without drama, holds a few small essentials (think: keys, a snack, and maybe a patch kit if you’re feeling ambitious), and won’t get in your way while riding. But if you were hoping to stash, say, a phone, wallet, or anything larger than a couple of protein bars, you’re gonna have a bad time. The material is decent, but the branding screams “cheap overseas knockoff,” which honestly just adds character. It’s fine if you need a small, no-fuss storage option, but if you pack like you’re prepping for the Tour de France, look elsewhere.

This is a small bag as described, but just right really, just big enough to hold phone, wallet and car keys. Material is not thick, but sturdy enough to last. Some people have noted the cheesy lettering...it does make it look a little cheap, but on the red version, the lettering is red and less noticeable.
