Join. Unite. Link

The M1 mountain bike helmet brings wireless communication audio to the trails. Sena’s proven Bluetooth® communication tech breaks barriers, creating a shared riding experience. Talk to each other. Make phone calls. Jam to your music. The M1 makes sure you #RideConnected.

Seamless design for easy hands-free communication
The built-in speakers are fully integrated and recessed above your ears, meaning no obtrusive headphones – this open-ear design allows awareness of your surroundings on the trail even as you listen to your music or chat with friends. The integrated microphone features Sena’s patented Advanced Noise Control™ technology, reducing unwanted wind noise.

Connected on the journey with bluetooth® intercom
The M1 features four-way Bluetooth® Intercom, letting you communicate with other riders wearing a Sena Bluetooth-enabled helmet. Up to four people can connect and converse on the trails within a range of up to a half-mile. The helmet also includes 2-way HD Intercom; a couple of friends connected get to experience high-definition sound quality in their conversations! The M1 provides a hands-free talking experience without the need for cell phone service or data usage. *Note: The M1 Bluetooth Intercom Helmet is not compatible with the M1 EVO Mesh Intercom Helmet.

Built for safety, comfort, and style
An integrated LED taillight dramatically increases your visibility to those behind you, while the included sun visor reduces sun glare. The numerous vents on the helmets enable airflow, keeping your head cool, while an adjustable nylon chin strap couples with the spin-lock adjuster to comfortably fit and stabilize the helmet on your head.

Connect to your smartphone for an enhanced ride
By pairing your smartphone to the helmet via Bluetooth® connectivity, the M1 allows you to hear GPS navigation, take phone calls, hear fitness app cues, and listen to your favorite tunes.

Energize your ride with Sena App
Simply pair one of your Sena helmets or communication systems with the Sena Cycling App for quick setup and easy management. You can pair/connect your device through the Bluetooth settings menu on your mobile phone. The Sena Cycling App is compatible with Sena's helmets and communications systems for cyclists.
