Ride Protected: 360° Rotating Bicycle Convex Rearview Mirror
Constantly twisting around to check behind you destabilizes your steering and takes your eyes off the path ahead. The CycleAddons bicycle convex rearview mirror provides complete rear-profile awareness in a low-profile, aerodynamic package. Built with high-definition convex optics, this handlebar safety mirror expands your field of view so you can spot oncoming traffic, passing cyclists, and trailing groups well before they reach your rear wheel.

Why Safety-Focused Cyclists Choose This Convex Handlebar Mirror:
- Wide-Angle Convex Lens Technology: Unlike flat glass mirrors that offer a narrow, restricted view, our specialized convex curvature widens your visual horizon to catch approaching cars across multiple lanes.
- 360° Multi-Axis Swivel Adjustment: Dial in your ideal viewing angle with ease. The smooth rotating pivot lets you position the mirror above or below your handlebars whether you ride an upright commuter, gravel rig, or drop-bar road bike.
- Shatterproof Polycarbonate & Polyurethane Construction: Built to withstand real-world riding conditions. The high-grade PC mirror resists shattering on impact, while the polyurethane frame absorbs road chatter and vibrations.
- Secure Expansion Plug Mounting: Designed for an exact fit inside standard 18mm to 22mm handlebar ends. Locks firmly in place using the included 5mm Allen wrench, preventing slipping or swivel drift over rough terrain.
