Quality mirror for a great price! Very sturdy, easy to install! I bought closed end ergonomic grips for my Aventon E-bike. I wasn’t sure this mirror would work, but the solution is simple-just took a box cutter and cut the end of the grip out. The mirror fits into the end and a rubber washer on the mirror butts up against the handlebar end to seal.
Installation was simple. The expanding mechanism is very secure. You can adjust the articulating screw separately and leave it just tight enough so you can hand adjust your view anytime.
I never had a mirror prior to this-let me just say, it is the best accessory I’ve added. I never realized how much safer I’d feel not having to constantly turn my head looking for traffic. It makes riding SOOO much better!

I very much recommend these mirrors. I've had many different mirrors before this. None of those were any good – some were too small, some were very distorted, some were difficult to attach, some needed constant adjusting. I didn't like any of those. But not with these mirrors. They are big, and the mirror is not at all distorted. They provide a crystal clear view. They are easy to attach, and they lock securely in your desired position. I'm so happy to finally find a mirror that works so well. You get a pack of two. I only need one, but am happy to have a backup. They are solid and seem high quality. You also get microfiber cloth to clean them and the hex wrench needed to attach the mirror to the handle bar and to lock the mirror in the desired position.

I just installed the BriskMore bike mirror on the left hand side handle bar of my converted Ebike. My original grips do not have the plug on the end so I had to cut it out with a sharp box cutter so the mirror mount barrel could slide into the front bar. As you turn the Allen screw clockwise it expands the mounting barrel inside the handle bar tube to mount securely.
The BriskMore mirror fits nice and tight. They supply an Allen wrench so you really don't need any tools at all to install it. The Allen key is used to mount the mirror and also to adjust the position of the mirror.
The mirror came in a soft pouch with a microfiber cleaning cloth and the Allen key. So far I am happy with the fit, function and clarity.

It's nice to have a rear view on both sides of your E bike. Nice clear views. Easy to install

It hasn't been until I have become a senior citizen that I have felt the need for a mirror on my bicycle. And of course they've come a long ways since I was a teenager riding my bike everyday. Having had a stroke years ago it is difficult for me to turn my head to look over my shoulder, or to ride one-handed and turn my torso to look behind me without crashing. This mirror has solved that issue quite easily and quite inexpensively. The mirrored surface is flat and clear with no distortion, and the back side is flat black with a nice star pattern reminiscent of a Texas Star. There's not a lot to say, because it's a mirror and it does the job that a mirror does, but this mirror has a great deal of adjustability to suit your riding positions and your needs to see behind you. Just remember to not tighten things down so tight that the rotating surfaces are unable to move. It was extremely easy to mount, very straightforward and simple. I own multiple bicycles and I have purchased this mirror repeatedly so that I have one on everything that I ride. I wouldn't drive my car without using my mirrors, I don't know why it took me so long to realize that it's just a good idea on a bicycle also. Extremely happy with this purchase and will continue to get these for any additional bicycles.

Bought the pair for our new electric bikes. It was a 5 min job to take the handlebar end plug off and mount this mirror. I adjusted it once I rode a ways, and loosened and slightly rotated it for perfect visibility. You can see the mirror highlighted in yellow. Pros: Because it doesn't stick out on a long arm like traditional bike mirrors, there is literally almost no vibration to distort the image. 5/5 Also, once you adjust the tightness of the mirror, it stays in place. It did not come loose at all on a somewhat bumpy stretch of residential bike path. 5/5 It takes up no real estate since it plugs into the end of the handlebar. 5/5 It looks extremely compact but the viewing area (especially because it is wide-angle) gives you a very good view to your rear. 5/5 Build quality is very good…I at first thought it wasn't going to tighten down in my handle bars because the shaft was in my mind somewhat skinny, but it literally took less than two turns for it to tighten with the supplied allen wrench (Kudos for providing the tool) 5/5
Cons: The ONLY con I see is because it sticks out of the end of the handlebar, it may break if you lean the bike on it. Or, you take a fall and it hits the ground. However, I saw in other reviews it didn't damage the functionality of it when it was hit…
Overall a winner!

I like that there is no assembly, just mounting them, and that is easy enough with the included hex wrench. I've had several mirrors over the years, and this pair of handlebar tip mounts are well engineered with simplicity and functionality in mind, in my opinion. Of course they do increase the overall frontal width, so I have to be careful not to bang them on doorway frames. I also always carry the hex key in with my bicycle tool bag in case it is needed on the road. This photo shows them mounted on my RADMISSION 1 e-bike.
