Key benefits See traffic behind you without turning your head: flat, wide-field mirror gives a clear rear view so you can ride more safely and keep attention on the road ahead. Fast on/off and comfortable to wear: lightweight, compact design slips on in seconds and sits comfortably on the wrist or forearm for the entire ride. Hands-free and vehicle-independent: wears on your arm instead of mounting to the bike, so it works on any bicycle and moves with you as you steer. Features and what makes it stand out Flat, wide-view mirror: engineered to maximize rear visibility while keeping a low profile that won’t catch on clothing or gear. Wrist/arm-worn design: designed specifically to be worn on the wrist or forearm rather than fixed to the bicycle, providing a consistent rear view as you change position. 360° rotation and adjustable strap: rotate the mirror to any angle to get the exact view you need; the wrist strap is an adjustable band that fits most wrist and forearm sizes. Lightweight and compact: easy to carry, quick to put on and take off, and comfortable for extended use. Function and compatibility Function: provides a rear-facing visual reference to monitor vehicles, cyclists, and other road users behind you without turning your head. Compatibility: wearable design fits most riders thanks to an adjustable band; works with any bike because it mounts to your arm rather than the frame. Size and fit: compact mirror head with an adjustable wrist/arm loop to accommodate a wide range of wrist and forearm circumferences. Practical use scenarios Daily commuting: keep an eye on traffic and opening car doors while riding in city streets or bike lanes. Group rides and touring: monitor riders approaching from behind so you can adjust pace or position safely without repeatedly looking over your shoulder. Urban errands or mixed-traffic routes: maintain situational awareness at intersections and while changing lanes, improving safety during short trips and errands. Care and operation tips Put on the band and position the mirror on the outer side of your wrist or forearm; rotate the mirror to set your preferred rear view. Remove quickly when not in use; store in a pocket or bag. Wipe the mirror surface with a soft cloth to remove smudges for a clear view. What you get A lightweight, wrist/arm-worn rearview mirror with a flat, wide-view design and an adjustable band for easy, comfortable use on any bicycle.
