There are lots of just-good-enough mirrors out there, but this is one exceeds. Government approved for speed pedelecs in Switzerland, this mirror meets strict requirements for quality and safety. The German-made Busch & Müller Cycle Star 80 is a left mount e-bike mirror with a 80 mm convex mirror that is sturdy and provides great visibility. It folds away when not in use (or when commuting through tight spaces).
Fits handlebars 17.2 – 22 mm
