In the same way as a bicycle helmet, a mirror provides an increased level of safety. While riding you can keep an eye on the traffic behind you without having to turn round. And looking behind you when overtaking is seen as one of the most important ways of preventing accidents.
A further advantage is that if you are riding with a trailer, you can use the rearview mirror to keep a constant eye on your children. When riding past obstacles, you can also use the mirror to judge whether the trailer will fit past.
It should be possible to attach the rearview mirror firmly to the handlebars while maintaining enough flexibility to allow precise adjustment of its position. Once the mirror has been adjusted to your personal seating position, it should not move - even on uneven terrain or in poor road conditions.
In Switzerland, a rearview mirror is obligatory for fast e-bikes with pedal assist up to 45 km/h, which is why a mirror is fitted as standard on every FLYER e-bike with pedal assist up to 45 km/h. Please contact your FLYER dealer for advice.
