Overview

The Sena BiKom 20 is a super-lightweight, helmet-mount communicator designed for cyclists, e-bike riders, and outdoor enthusiasts who want hands-free group communication, phone connectivity, and navigation/audio streaming — without needing a specialized smart helmet. Weighing just 20 grams, it clips onto your helmet strap or cap and instantly turns any helmet into a communication-ready system.

Key Features & Connectivity

Mesh Intercom 3.0 + Bluetooth 5.2 — lets you communicate with fellow riders using Mesh (up to ~0.5 mile range in open terrain) while also connecting to your phone for calls, GPS directions, music, or other audio.
Ultra-light & Compact — at just 20 g, the BiKom 20 stays almost unnoticeable, avoiding interference with helmet fit or rider comfort.
Advanced Noise Control™ & Flip-down Microphone — reduces wind and ambient noise for clear communication; mic can be flipped up/muted to spare others from heavy breathing or road noise on climbs.
Universal Fit & Quick Mounting — includes multiple strap-mount options and a cap-clip so you can attach it to most helmets (road, mountain, commuting) or even a cap in seconds.
Over-the-Air Updates & Sena Cycling App — firmware updates and settings adjustments done via smartphone, keeping the unit current with new features and improvements.
