Bike Mirrors 2pcs Bar End Bicycle Mirrors for Handlebars - Cycling Lightweight Rear View Mirrors, Safe Rearview Mirror for Mountain Road Bike

These mirrors are easy to install on my bike, stay in place even after a ride on the car/interstate. They are not overly large but serve the purpose of seeing if something/someone is coming from behind you - the “lens” is clear enough, it’s sturdy and adjustable- I bought another set as they are reasonably priced -

I use this mirror on my Brompton p line and c line bicycle and they work perfectly. It’s basically a one tool installation. All you need is the right size Allen wrench and they tighten right up in the end of the handlebar. I like that they fold up out of the way so that when I fold my Brumpton bike, they don’t hit the ground. Highly recommend!

I needed a quick replacement for cat-eye bar end when the mirror popped out and left me. The two-pack of these gave me a spare to keep on hand. Construction is of decent resin-type material, the adjustment screws are hex (although differing sizes). If the expansion collar doesn't seem to be large enough to grasp firmly a bit of wrapping tape can sort it out. The mirror is of reasonable size and slightly convex as would be expected. Whether the mirror stays in when bounced hard-- we shall see.

Very easy to install. It was a little tricky to remove the clear protective film but once removed the view was clear. Does not shake while riding and despite their small size I can see plenty. I am happy with this purchase.

The mirrors are easy to install but a bit flimsy. The mirrors itself are on the smaller size and a little distorted. Also, one of them rattled and I am trying to figure out how I can fix the problem.

Inexpensive and does its job well. I put them on my electric scooter and they work great for the price.

Designed to fail. The plastic is weak especially given the small diameter of the parts (stem connecting to ball socket). The mirror broke off in my hand as I was trying to remove the protective film. Never even got to use it. Total waste of money!

These are awesome little mirrors. They have a film on them that is very hard to get off but a little scraping at the edge to give it a little bubble and then be persistent and you will be able to pull it off. Doesn't take extra room on my ebike (which has many things on the handlebar already). Very easily moved around and not oversized, just enough to see cars coming from behind. Perfectly fit end of handlebar. And, 2 in package means 1 for each ebike for the traffic side of the bike. Very small but I don't need a big mirror to see a car behind me.
