Hafny 2021 NEW Bar End Bike Mirror: HD Glass Lens, Shatterproof, Large Surface - Ideal for E-Bikes Review

Not suitable for openings under 20mm. The inner part, which clamps it, has a diameter of 19 mm (even with the expander removed). It clearly states that it will fit handlebar holes from 14.8mm to 23mm. Not true.

I bought 2 of these to fit my newly purchased Lectric eBikes. They are easy to fit and offer many options to cover different handlebars. I used the basic installation and it turned out to be very stable. Their shape offers excellent visibility.

This is a large mirror so you can see a large area behind you. The mirror itself is made of glass and is therefore easy to clean. However, which company gives you an Allen key that only tightens two of the three screws? The third required a different size key than the one provided.

My old one fell down and broke. This mirror is larger and gives a very good view of the road behind me. It was very easy to install and set up. You will need a second Allen key. A screw of a different size. This is a minor issue. Otherwise great mirror! And I drive 30 km in city/rural traffic - that's how it should be.

Very easy to fit and the same mirror fits our two bikes with different handlebar diameters. Love the ability to fold onto a bike rack for easy loading. Easy to set up, but takes a try or two to get the tension right to balance adjustability and stability (to keep the mirror in place when driving over rough sidewalks/paths). Overall great value for money. highlighted.

Well made with quality materials, fits my Shimano handbrake perfectly. The position of the mirror allows you to keep an eye on everything in front and behind you. The only small issue I had was with the Velcro. If it is overtightened it can affect the function of the switch, ie too tight and can restrict the switch's travel through the handbrake/shifter assembly. Otherwise a great mirror to watch vehicles behind you.
