Aerodynamic Smart Communications Helmet

The R2 is an aerodynamic Smart Cycling Helmet designed for road cyclists. The R2 features a Bluetooth® Intercom communication system for rider to rider conversation, plus smartphone pairing for music, GPS, cues from fitness apps, and more. The R2’s impressive featureset is a nod to Sena’s original R1 smart helmet, but the R2 takes things to the next level with a new design and an integrated taillight.

PROTECTION AND COMFORT

The sleek helmet also features a built-in taillight, improving your visibility to others on the road. In addition to the convenient taillight, the R2 bike helmet is built to withstand an impact, providing necessary protection thanks to an in-mold polycarbonate shell. The helmet is lined with removable and washable inner padding, a smooth nylon chin strap, and a spin lock, all for superior protection and a secure fit.

COMFORT AND SAFETY

The S1 features a built-in taillight with advanced adaptive lighting that improves rider visibility like never before. With four brightness settings, you can enhance clarity in different lighting situations. The S1 provides a greater level of visibility with its adaptive light technology that illuminates in bright solid color when deceleration is detected. The S1 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 superior protection and a secure fit.

PAIR YOUR SMARTPHONE FOR MUSIC, GPS, PHONE CALLS +

By pairing your phone to the helmet, the R2 allows you to hear GPS navigation, take phone calls, hear fitness app cues and listen to your favorite music. Pairing your phone to the R2 allows for safe and hands-free access to many of the functions on your phone.

RIDER-TO-RIDER COMMUNICATION WITHOUT THE SHOUTING

Sena’s Bluetooth® Intercom technology allows for up to 4 riders to connect and chat from helmet to helmet at a range of just over a half mile (900 meters). When connecting with just one other rider, users will experience HD intercom quality. Audio is delivered through built-in speakers located just above the ears, which allows for awareness of surrounding sounds such as traffic, unlike in-ear buds. Located in the front of the helmet is a seamlessly integrated microphone that features Sena’s patented Advanced Noise Control™ technology, picking up and transmitting your voice more clearly.
