I have a Sym Symphony scooter with spikes in its design. These mirrors are the most stylish ones I have ever installed on my bike. The factory ones had rusted and were ruining the overall look of the scooter. These ones have a smaller field of view compared to the factory ones, but they have something amazing that I haven't encountered in other aftermarket mirrors. They have an arm at the point where they screw in, which, depending on their rotation, extends the mirrors outward, allowing you to adjust their field of view according to your needs. This particular feature gives them such a unique design that makes them very elegant. I ordered them in Carbon color, but they were not available from the importer, and they informed me that only black ones are available. I have not regretted my choice for a moment, and in future bikes, I will choose them again to get rid of the unreliable factory ones! They also come with 3 sizes of screws to fit all bikes.
Update: After a few days of use, I have noticed that while the product is good, it is not suitable for Greek roads. In every pothole or drain I encounter every few meters, the bouncing momentum disrupts the correct angle of the mirrors, resulting in loss of visibility. This happens because there is a screw in the joint that has a specific tightening range and stops. When they were designed, they did not take into account the terrible roads we have. The solution for me is to adjust the correct angle that suits the rider and then apply glue in the form of plasticine to lock it permanently in place. Of course, this assumes that the bike is ridden by one rider. As for the design, the mirrors continue to impress me despite their functional problem, and I will keep them with the patent I mentioned.
