NDakter Bike Triangle Frame Bag, Bicycle Storage Pouch with 2 Side Pockets, 3-in-1 Top Tube Bags for Phone, Waterproof Cycling Tool Accessories Pack for MTB Mountain Road Bikes（1.2L）

Excellent. Roomy. Multiple mounting options. Looks to be very durable. Waterproof material. Great zippers.

My seatbag kept getting in the way of my rear flasher light. So I needed a bag that could be located somewhere else on the bike. This bag turned out to be perfect. It hangs from the top tube and I loosen the straps so that it can slide sideways along the tube. I needed that because when putting the bike in my trunk the handlebar needs the bag to be all the way to the left. But if I'm carrying a second water bottle the bag needs to be moved to the right. I also like this bag because it has two side pockets and a big main pocket I put everything in my main pocket except my cell phone which I put in one of the side pockets and it fits perfectly (Galaxy S25).

Works amazing, i put mine right under my seat because my suspension takes most of the space inside the frame. holds most trail tools plus my phone and doesn’t wobble very much. One thing i’ll say is that i have a medium large bike, and any smaller might create issues with the dropper post but it fits perfect for me.

Good small bag, good quality and looks pretty nice, but I bought it to use as a frame bag per the description, and unfortunately the location of the zipper makes it close to unusable for an under-tube location. As a top tube bag it works fine. I gave it to someone else that was looking for a top tube bag and it works well for them.

Good

Fits well on a small bike frame. I have it set up vertically. This bag can fit at least a small air pump, a couple of gel/powder packets, a flat toolkit and a small cargo net. It has one main compartment and 2 slim side pockets.

So the bag overall seems good build quality for the price, but the storage capacity seems smaller than advertised. I can only fit a phone and wallet inside before it’s at capacity, which helps but not a lot when trying to carry other small things like snacks, tools, etc. Installation was easy enough, although the Velcro straps were longer than I’d like. Speaking of installation, the material on the velcro straps seems to have left a paint or whatever material residue on my bike frame, which I have been unable to get off completely. Not sure if it’s a product defect or due to hot weather, but definitely something to keep an eye out for. Luckily my frame is black but it may stand out on your bike if it’s another color

I have a RadPowerBikes RadRover 6, it works pretty well on that frame. For the size of it too it's pretty small in footprint but can hold a decent amount of stuff! Love it and would recommend for anyone looking for a somewhat budget frame pack option!
