Arkham bar-end bike mirror for 0.59–0.65" handlebars, Pentagonal B Pair, automotive-grade glass and 11 cm arm

Arkham's bar-end bike mirror is a pair of pentagonal, automotive-grade glass mirrors that mount in 0.59–0.65" handlebars to give a wide, adjustable rear view with 360° rotation and shock-resistant stability.

Replace guessing with clear sight: these bar-end mirrors use thickened, auto-grade convex glass to expand your rear vision while resisting glare, scratches and shattering. Each mirror mounts inside the handlebar end so your arms don’t block the view, and the unit ships with two plug sizes, an 11 cm extended arm and an anti-loosen design to suit most bicycles, e-bikes and scooters. The set is designed for straightforward installation using the included Allen key, and the mirrors pivot on a universal ball joint for precise aiming.

How does the Arkham mirror improve rear visibility when cycling?

The pentagonal, convex automotive glass broadens the field of view compared with flat mirrors, letting you detect traffic and cyclists behind you sooner. Anti-glare treatment and a matt-blue edge reduce distracting reflections while keeping the image clear.

• Wider, convex viewing surface for extended peripheral vision
• Automotive-grade glass minimizes distortion and scratches
• Glare-resistant finish improves clarity in bright light
• 11 cm extended arm places mirror beyond shoulder obstruction

Will these bar-end mirrors fit my handlebars and survive rough roads?

Yes—Arkham includes two medium-sized expanding plugs to cover common handlebar inner diameters. The mirror body and plug use an anti-loosen mechanism plus a shock-absorbing design so the mirror holds position over uneven terrain.

• Two plug sizes: fit 0.59–0.65" and 0.65–0.79" inner diameters
• Secure expanding plug prevents rotation or slip
• Shockproof construction reduces vibration blur
• Durable metal and composite components for daily use

How adjustable is the mirror once installed?

The mirror pivots on a universal ball joint that allows 360° rotation and precise tilt, so you can set it for your riding position and fine-tune sight lines on the fly. The anti-loose lens design keeps adjustments locked in place.

• Universal ball joint enables full rotational range
• Tool-assisted clamp tightens securely after aiming
• Mirror face tilts for seated or standing riding positions
• Matt-blue edge improves grip and stability at the lens junction

How simple is installation and maintenance?

Installation is intended to be quick: insert the correct plug, tighten with the included Allen key, then position and lock the mirror. Routine upkeep is minimal—clean the glass with a gentle microfiber cloth and check the clamp occasionally for tightness.

• Includes necessary Allen key and two plug sizes
• Step-by-step video and instructions available from Arkham
• Clean with mild detergent and soft cloth; avoid strong solvents
• Periodic clamp check keeps mirror secure over time

Who this is for: riders who want a durable, low-profile mirror solution that delivers automotive-style clarity and a wide field of view. The Arkham bar-end mirror pair is ideal for commuters, urban cyclists, e-bike riders and anyone who prefers bar-mounted mirrors to handlebar-stem attachments. If you have 0.59–0.65" inner diameter handlebars (or 0.65–0.79" using the second plug), want a vibration-resistant mounting system, and value a broad, glare-reduced rear view, this mirror set is designed to meet those needs without adding bulk to your cockpit.
