- High quality construction: durable ABS plastic housing with clear acrylic lens and silicone mounting sleeves for a secure, stable fit. - 360° adjustable rear view: 360-degree rotation allows the mirror to be set at any angle. The glass rear view mirror can be attached on either the left or right side so you can clearly see traffic behind without turning your head. - Easy to install and use: mounted at the end of the handlebar with a silicone sleeve. Flip the mirror to view the rear instantly, and rotate away when not needed for a low-profile look. - Wider field of view: the mirror measures 3 cm and uses a clearer convex lens to expand the viewing area, helping you see surroundings and traffic behind you and improving cycling safety. - Use scenarios: ideal for daily city commuting, rides with family or friends, and urban or park routes where quick rear visibility enhances awareness and safety.
