Overview

The Sena Pi is a compact Bluetooth intercom system that transforms nearly any cycling, skating, or multi-sport helmet into a smart-communication helmet. Instead of buying a full smart helmet, Pi clips onto your existing helmet straps, giving you hands-free intercom, phone, music, and navigation audio — all compatible with Bluetooth-enabled devices.

Core Features

2-way Bluetooth intercom — lets two riders communicate directly without cell service or data, over a range of up to ~400 m (≈ 0.25 miles) in open terrain.
Helmet-strap mount design — easily clamps to most helmets with straps up to ~18 mm wide, allowing reuse of your current helmet.
Smartphone pairing — connect your phone via Bluetooth to stream music, listen to GPS navigation, or take calls through the Pi audio system.
Noise-control audio system — reduces wind and ambient noise so communication and audio remain clear even at speed.

Performance & Battery

Up to ~6 hours of talk/ audio use per charge — enough for typical rides or commutes before needing recharge.
Rechargeable via USB-C — easy to recharge between rides.
Lightweight and discreet — minimal bulk added, preserving helmet comfort and fit.

Use Cases

The Sena Pi is ideal for:

Casual or group rides — easily communicate with a riding partner without stopping or shouting.
Commuting — get GPS directions, take calls, or listen to music safely while keeping awareness of surroundings.
Riders who prefer their existing helmet — convert it into a smart helmet without purchasing a new helmet altogether.
Multi-sport use — works with cycling, skating, riding, or any helmet with compatible strap configuration.
