GUB Bicycle & Motorcycle Phone Mount, Aluminum Alloy Universal Bike Handlebar Phone Mount Holder Adjustable Compatible with iPhone X XR Xs 7s 8 Plus,Compatible with SamsungS9/S8/Note5/4 (Black)

I ride 2000+ miles a year. This phone mount makes all the difference. Easy to put the phone on and off. No bumps can ever dislodge it. I like its clever design and small form factor and weight.I recommend these to all my family and friends.

Super

It holds my phone on a bicycle. I wouldn’t trust it for a motorcycle tho.

Clamp grips securely without damaging the phone.

This is the only phone holder I buy. For all my bikes its the sleekest looking 1

Seems decent for the price. If youre looking for for better quality, stop being a tightwad and order a ram mount.

Wow. Great piece of gear to hold my cellphone, very durable at a good price. And it arrived in two days! (east coast).I'm going to use an old iphone 5 as a bike computer. I like how it mounts pretty close to my handlebars. The stem is only 23mm in length (the chassis adds another 8mm in height). I noticed the version that allows the phone to rotate has a stem about twice as long.You definitely have to be careful mounting the bracket around your handlebars, especially if you have carbon bars. It's printed on the bracket that you should tighten to 6Nm. The max diameter is also printed, 31.8mm, which is the std diameter of bars for a road bike. There are also fillers included to allow mounting on a smaller diameter bar.For being CNC machined out of metal it surprisingly only weighs 3.5oz. My iPhone 5 weighs 4.2 oz.The package also comes with six rubber pads, four of which you affix to the little feet that hold the phone. Two are extra. In addition, there's a longer screw to mount it on your bike stem. I'm not sure that screw will fit my particular headset but I don't plan to use it as I'd rather have my phone farther forward anyway.So for less than $15 I don't have to cough up $250 for a bike computer. I always want to take a phone with me, so the total weight gain is about that of a bike computer (of course, not as aero as one and not waterproof!).I'll update the review after a few rides with it.

not very impressed with this mount. for starters, the screw that is needed to use the mount with the clamp was unusable because metal was basically covering the hex shape where you insert the allen key (you will see a glob of metal on the screw head in the picture). when you are waiting for days for an accessory you need, and are confronted with this, it's naturally annoying. does someone really need to go to a hardware store to hunt down a suitable fastener to make the product work as advertised ? While talking about advertising, take note that when they show you that the mount can be rotated on it's clamp, you'd be forgiven to think that's possible on the fly .... it is not - you will need to loosen the screw holding it to the clamp and index in 90 deg increments .... because the fixing point on the holder is a cross that fits into a cross on the clamp, and neither one has built-in free rotation.if you wish to mount this using the included stem screw, take note that if you have a nice headset, you will end up gouging it because the mount has 2 screws on both left/right that protrude out the back where it would come to rest on your stem/headset cover. if your stem/headset cover is domed rather than flat, you may fare a little better with mounting. either way, it does not look like a well thought out solution.Concerning performance, the claws are short, will work well with a bare/naked phone, but one with any case on it (even a slim one) there is less confidence that the mount can do it's job unless you don't mind squeezing down on the clamp for peace of mind.the screw mechanism is flimsy. if your riding without your phone mounted you should tighten down all the way closed, else the mount will rattle.i would have expected a more precise/firm feel with that adjustment screw, since it tends to loosen when riding (vibration).
