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.

PREMIUM FEATURES FOR COMFORT AND SAFETY

The R2X houses an integrated LED taillight. With three brightness settings, you can enhance rider visibility based on your particular lighting situation. The R2X is also safety-certified and built with a protective in-mold polycarbonate shell. The helmet, lined with removable and washable inner padding, features a smooth nylon chin strap, and a spin lock for a secure fit.

COMMUNICATE HELMETTOHELMET WITH MESH INTERCOM™

Sena’s Mesh Intercom™ allows riders to communicate hands-free with any other Mesh user (R2 EVO, R1 EVO, M1 EVO) within a half-mile range (900 meters) with the touch of a button. Multi-channel Open Mesh offers 9 channels, letting you switch between groups on different frequencies. Sena’s Mesh platform offers flexibility by allowing riders to come in and out of range while keeping the rest of the group connected. Whether you are riding with one other person or a group, the R2X will take your ride to the next level. Audio is delivered through integrated speakers located above the rider’s ears, which allows for awareness of surrounding sounds such as traffic, unlike in-ear buds. Located in the front of the helmet is a built-in microphone that houses Sena's patented Advanced Noise Control™ technology, picking up and transmitting your voice clearly.

SMARTPHONE CONNECTIVITY

Bluetooth® technology allows you to connect to your smartphone, enabling you to tap into Alexa Built-in, make phone calls, listen to music, hear GPS navigation, and even connect to fitness apps. The Sena Cycling App allows riders to conveniently take control of the R2X's features. Through the app, you can create groups of friends to easily connect with, control taillight settings, manage multi-language voice prompt selection, and access the Quick Start Guide on the go.
