Pairing your Sena helmet or communication system with the Sena Cycling App is simple. Check compatibility, connect via Bluetooth in the app, and manage your device settings and features. Stay seamlessly connected on the road with Sena Cycling App.


Sena’s Mesh Intercom™ allows riders to communicate hands-free with other Mesh users (R1 EVO, M1 EVO) within a half-mile (900 meters) with the touch of a button. Multi-channel Open Mesh supports 9 channels, letting you switch between different 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 large group, the R2 EVO 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. The redesigned speakers have been optimized in order to keep the helmet as slim as possible for less wind resistance. 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.


The R2 EVO is available in sizes small, medium, and large in Matte White, Matte Gray, and Matte Black.
