Incredible quick release!
I have one of these already in another brand but I have to undo the Velcro when I want to take it off. That one is really nice but this one tops the charts! When I ordered it I didn’t even realize how much better it would be. This one has a quick release tab that you just push in it and then slide the whole unit off. Done. Just like that. It is so quick and simple. And the quality on the whole unit wasn’t compromised with putting the effort into the clip. They kept up the quality throughout the entire holder. They even included a rubbery silicone grip that goes onto the bottom of the clip against your bike so it won’t scratch your bike and so it won’t twist around. It holds incredibly well. There are three threaded clips that wrap around your bike to hold the quick release slide unit. They are tighten by a threaded screw and as you twist it tightens. And wow. Does it hold. This thing will not move once you tighten it. I am so impressed. I had this on my bike within a couple minutes and just gave my son the other one I had. I wasn’t giving this awesome phone and item holder up. It’s built really well. It fits my iPhone 14 Pro Max perfectly. Recommend 100%

Great alternative to a under seat bag
I’ve always used an under seat bag on my bikes, but with a new very streamlined/aero bike thought I’d try something different. This is a very practical alternative. It’s big enough to hold a spare tube and lots of other stuff like multi-tools, phones, etc. The mounting system is very clever – 3 loops through a fixture with plenty of cushions to prevent scratches and very adaptable to different top tube diameters. Also very easy on and off with a simple latch on the mounting fixture. I put my bike phone under the clear plastic where it still responds to touch and I can see all the key stats. Very happy with this new approach and look forward to lots of miles with it.

Handy Bike Bag. Phone-Friendly.
This bike frame bag is a cyclist’s dream. The lightweight, waterproof design holds phones (up to 6.8”), keys, or snacks, with a TPU touchscreen for navigation on the go. The quick-release mount attaches securely to top tubes, and it stays stable on bumpy trails. Used it on mountain rides, and my phone stayed dry and accessible. The EVA shell adds durability, though the zipper can be stiff when overpacked. Perfect for road or trail biking.Overall, I can easily recommend this bag for cyclists needing a compact, rugged phone mount.

Do not buy!
Does not fit stem of bike. Top tube will work but will scratch the paint!! Avoid!

Sadly no, returned due to lack of fit
Neat bag, decent construction, end up having to return due to the shape of my frame. I wish the mount was farther back. Was waaaay too tall and bulky to mount on my bars.

Steady and firm fit on my bike. I drive in tough terrain and it did not move. I like it.

Brilliant design
This is ultra lightweight and very easy to instal – it clips on in a second. It can be used to store some essentials in the bag and the top allows you to mount your phone and use it via touch screen. Great design, very convenient.

Gutes Produkt auch für Rennräder
Hält super fest besser als gedacht behindert nicht den Lenker und die Beine beim fahren auch für Rennräder super geeignet behindert vielleicht leicht bei anstiegen. Wenn man aufstehen muss um zu treten sonst kann mich nicht beschweren. Der Preis ist vielleicht ein bisschen zu hoch angesetzt aber das Produkt tut, was es soll.
