Review on 🛵 Enhance Your Riding Experience with kemimoto ATV and Motorcycle Rear View Mirrors: 360 Degrees Ball-Type Adjustment, 7/8 Inch Handlebars, 8MM and 10MM Screws Compatible with Sportsman Scrambler FourTrax Snowmobile Bicycle by Ryan Olsen

I installed them on my electric scooter and they are terrible. If you don't have connectors on your handlebars, forget it when it comes to installation: the included brackets are metal with no rubber grommet, meaning you'll never be able to get a metal handlebar tight and secure, metal to metal. Pivot axis adjustment is via a non-locking bolt that prevents rotation in only one direction: if you push them in with rotation in the other direction, they immediately disengage without resistance. In terms of functionality, these mirrors represent a very narrow field of vision. Even perfectly adjusted, almost nothing can be seen. Wide-angle mirrors would be much more useful.
