Super convenient, waterproof top tube pouch. Easy to install and move between bikes.
I’m overall very happy with this bag. I’ve never used a top-tube pouch like this before and didn’t realize how convenient it would be to have right in front of me while riding. It’s perfect for keeping my phone or sunglasses handy/ I can pull over, grab my phone to make a call or snap a photo, or put my sunglasses on or off without digging through a backpack or stopping to unzip anything.It doesn’t get in the way at all while riding, and the material feels well made — sturdy but not rigid or bulky. It’s also very waterproof, which is important where I live in the Pacific Northwest with frequent rain, and it has kept everything inside dry. Because of its slim design it is not large – you kind of have to pick what you want in there, so maybe phone, keys, earbuds fits well, or sunglasses and phone.The magnetic snap closure is a nice feature. It’s easy to open and close and feels secure, and I appreciate not having to deal with a zipper while riding. I also like that it attaches with Velcro instead of screws. I didn’t use the screws because I want to be able to move it between different bikes depending on who in the family is riding, and it’s very easy to un-Velcro and transfer.The only minor thing is that there aren’t really instructions included. I had to look back at the original listing video to see that one strap is meant to attach up near the handlebars. At first I had all three straps underneath and it wasn’t as secure. That might have just been me missing something during unboxing, so I’m not really marking it down for that.Overall, it’s a very convenient, well-designed little bag and would recommend

Sized modestly, practically designed
The capacity of this product is actually fairly practical. Modern frame geometries might not have a place for this. Simples geometries and older ones will fit it perfectly. There’s no zipper, the bag is magnetic. The cool thing I think about this bag is its design. Its designed in such a way as to ensure top down and side water entry. No, it wont survive pressurized water: but you likely aren’t going through a car wash! So the design is really half the water proofness, on top of the quality materials used. The straps do their job and are essential! You can fit a normal sized phone and a few affects in here. All things considered, I would say its a pretty good value and decent addition to a city bike.

Not Worth the Price
Size is fine, but not great quality. One of the three Velcro strap hooks broke with minimal pressure, and the clasp is questionable – I would not trust this bag with my wallet, phone, or keys! I recommend looking for a better option.

Bag rattles if using the screws
Good bag but rattles too much just using the screws I didn’t want to use the straps.

Compact and Convenient Storage for Everyday Bike Rides
I have been happy with this bike frame bag for carrying the essentials on shorter rides. It is just the right size for my phone, wallet, keys, a small multitool, and a few other small items without adding much bulk to the bike.The magnetic flap is one of the best features. It is easy to open with one hand while stopped, and it stays securely closed while riding. The waterproof material also gives me confidence that my belongings will stay dry if I get caught in light rain.Installation was quick using the hook and loop straps, and once tightened the bag stayed firmly in place without shifting around. It also has a clean, low profile design that does not interfere with pedaling.If you need to carry a lot of gear, this bag will be too small, but for everyday essentials it offers a nice balance of storage, convenience, and durability at a reasonable price. I would definitely recommend it for commuters and recreational cyclists.

does the job.
The only recommendation hopefully companies will listen, is that they need make one that locks in case i want put value stuff into like my Fox gloves which where stolen before.

Waterproof Bike Bag that fits Top Frame Tube, or Front 45 Frame Tube
This is a fairly small, very lightweight bag that comfortably fits on the top frame tube of your bike. The three velcro straps keep it stable both horizontally and vertically. The case is hinged and the upper flap completely covers and drops over the lower part, keeping it pretty waterproof. The material has a vinyl feel to it, and is easy to wipe clean if it gets muddy or dirty. Plenty of room to bring along a few tools or accessories when riding, but don’t expect to fit anything huge in there, maybe some snacks. There’s also an alternative mounting kit in the form of some screws that can allow for this to mount onto a standard water bottle holder mount.

Doesn’t get in the way
I really like this pouch, much more sleek and compact than my bulky handlebar bag I normally take around with me. This pouch works well for when I’m on rides that I don’t want or need to take much along with me. Slim enough to not get in the way of my legs while I’m pedaling and large enough to hold my phone, wallet, and one or two extras. I really like the design of the flap. It locks magnetically and with a hidden latch that keeps it from flapping back up when I hit bumps or whatnot. Love the sleek look and design of it. And it fits well on my bike. I chose to mount it not with the bolts, but by the velcro straps so that I can easily remove the bag when I have to go in a store. Much easier than having to remove everything from the bag and potentially losing whatever I shoved in there because I’m juggling everything in my hands. I think it’s well worth its price for the quality and design of it, I’m very happy with it. It’s very durable, and can confirm that it is waterproof. It still looks great after having and used it for 2 months almost every other day.
