ROCKBROS Bike Phone Mount Handlebar Holder 360° Rotatable Aluminum Cell Phone Holder for Bicycles, Motorcycles & E-Bikes

This. Is. Awesome! Build quality matches my bike's, very solid. Came with an allen key/wrench to put it together, and it was easy. This is machined from various aluminum alloys, the bolts are chromed steel and quite heavy, a little long - BUT it comes with shorter screws that I could also use by putting it in a slightly different position on my bars. It is a little heavy for a phone mount however it is vastly more solid than any plastic holder could ever be, and that is important to me. There are silicone rubber inserts that you put on all of the phone mounting points. This thing holds solidly, does not flex at all, zero flex in this. There is a plastic ring that goes around your bars prior to putting on the holder. I like this!

I ride to the beach and on some really bumpy dirt trails on my fat tire e-bike and this thing keep my phone in place. Easy to install and use and aluminum construction won’t rust in the humid salty coastal air. Works well overall.

This fits perfectly on my Trek FX1, along with all the other gadgets I insisted on mounting on my handlebars. I live in Manhattan and my bike is like my car -- it's my primary mode of transportation 10 or so months out of the year. This phone mount is perfect for keeping my phone in view and out of my hands, especially when I'm riding somewhere new and need a map/directions visible and audible. The screw-type grip is very effective over any bumps and even during a few unfortunate spills. (This could be a downside if you want to quickly access your phone, like some handlebar mounts might allow.)The only thing I would add/mention is that I purposefully did NOT install the small rubber/silicone pads which grip the sides of the phone. I use a leather case from Apple, so the grip is somewhat snug on that without using the silicone grips. This way, the phone is more snug because it fits "under" the little tooth at the top of each grip. With the silicone added, I think the phone would be snug based solely on squeezing from the sides; this way, it's squeezed from the sides AND there's a tiny little edge to on the top of each grip which holds it in place using more than just friction. Otherwise, the silicone grips would prevent the phone from fitting under the tiny tooth/corner. (I don't know if I explained that well at all, but the moral of the story is: great mount, and my altered use does not mean it gets less than 5 stars.)

It is a very rigid mount, no swivel, the clamp screw is extremely fine threaded and takes several turns to loosen or tighten. It does grip my phone w/rubber case very well

I made the mistake of buying a cheaper, plastic, phone holder. It had bands that strapped around the phone giving the appearance that my phone would be safe if the holder broke. Well, it broke in a key place where the rubber straps were of no help. I had just finished a ride with downhill speeds of 30mph and was crossing a dirt path to another road when it failed. Fortunately, it fell into a grassy at a slow speed.I replaced the broken cheap model with this Rock Bros. It is much better quality. However, even though I think it is unlikely to break, I re-purposed the rubber straps from my old holder and use them on the Rock Bros as an added safety measure. The strap is connected with a zip tie to the handlebars.Overall, I am very happy with this phone holder.

We used these on our E-bikes to hold our iPhone pro max while ridding. The installation was simple and holds the phone very stable. You can turn the dial on the side to tighten down your phone so it is secure and there is very little chance of losing it. We are very satisfied with how well it works.

Seems like a sturdy product. But where are the installation instructions? I have extra pieces that do not seem to fit anywhere.

The edge pads are not thick enough and therefore sit too shallow. The upper part of the edge tabs (made from aluminum) stick out over the pads and dig into the phone or phone case. If you have a thick phone or a thin case, this will absolutely destroy it.I have a nice hard rubber case on my z fold 4. With the addition of heat-shrink tubing, I believe that I can make this work. Otherwise, I like this holder.
