Bike Mirror, Bike Rear View Mirrors, Durable and Easy to Install, Adjustable Rotatable Handlebars Mounted Plastic Convex Mirror for Mountain Road Bikes

These small lightweight mirrors are super easy to install on your handlebars with the adjustable buckle and can then be rotated in any direction to provide you with the best possible view for your riding position. The view is very clear. The mirror itself is slightly set back from the casing - giving some protection from rain etc - and is firmly glued in, but the whole thing appears slightly flimsy so I'm not sure how long they will last. However, they are so cheap that if you find them helpful, you could buy another set for spares.I wanted them for my ebike and although they do fit the handlebars, I can only use one, as the right hand one gets in the way of the gear lever - but the left hand one can be adjusted to provide quite a good view anyway.

This was for the e bike to replace a broken one.Though it’s stated that it will fit the majority of electric scooters etc, I found it difficult to attach to the wide handlebar as it was extremely fiddly. Therefore the angle to view isn’t the best, and I have to strain to use it when cycling. It does the job, but I don’t solely rely on it for viewing, I double check before any manoeuvre, which kind of defeats the object for me!
