The B&M Cycle Star 913/712 impresses with its certification "E" as an E-bike rearview mirror across the board. A short, curved arm and the extended mirror surface in a pentagonal design allow for good visibility in road traffic. In the event of an impact, the mirror automatically folds down (special feature of model 913/712: additionally manually operable folding function). Thus, it meets all the quality criteria to be approved for fast E-bikes. Installation is possible only on the inside of the handlebars (Ø 17.2 - 22 mm).
