Group rides should feel effortless — not like shouting into the wind. City rides should feel confident — not like hoping drivers see you. Lumos Sonorus brings mesh intercom and 360° visibility into one helmet, so you can talk freely, signal clearly, and stay aware wherever the ride takes you.

Sonorus integrates Mesh Intercom tech, co‑developed with Reso, letting you talk and stay connected with your crew – wire-free, effortless, every mile.


It’s hard to chat while riding — shouting over the wind steals the fun and can compromise safety. The built-in full-duplex mesh intercom lets you talk freely with friends up to 1 mile* away. Real-time, two-way communication keeps every conversation smooth, connected, and effortless.
*Tested up to 1 mile in open, unobstructed conditions. In dense city environments with heavy signal interference, the intercom range may be reduced to around 0.3 miles.


As riders drift apart, conversations stay smooth and uninterrupted. The mesh intercom automatically links up to 15 riders, keeping everyone connected even as the road pulls the pack apart.






High-fidelity sound for music, podcasts, calls, and GPS navigation via Bluetooth — for every group ride, solo ride, and daily commute.


Traditional in-ear headphones can isolate you from your surroundings. Sonorus’ open-ear design delivers rich audio while keeping you aware of traffic and the world around you.


Most intercom solutions make you choose — music or intercom. Sonorus lets you do both at the same time. When your team speaks, your music automatically softens, so you can keep listening while staying connected to the group.


Sonorus’ light system is TÜV verified for 360° visibility, helping you stay visible from every angle in rain, fog, and low-light conditions


Drivers can’t read your mind. Sonorus lets them know instantly.

Sync your helmet and bike lights to glow as one with your group.Ride solo or roll in a pack — stay more visible to drivers and claim more space on the road.



Certified to the NTA 8776 standard for e-bike helmets, Sonorus is crafted for urban daily commutes. With elevated safety benchmarks, you can ride with confident, reliable protection.


Mips is a widely recognized helmet safety technology that uses a low-friction layer inside the helmet to help redirect rotational motion from certain angled impacts — adding an extra layer of protection beyond standard impact absorption.


Designed to wrap deeper. The extended shell protects the vulnerable back of the head where standard helmets fall short.

Decades of riding experience, plus valuable feedback from over 500,000 users, shaped every upgrade. Sonorus is engineered to deliver superior comfort, breathability and protection from the very first mile.

Refined in professional wind tunnel tests, our precision-tuned vents and internal airflow pathways pull heat from your head nonstop. Stay perfectly ventilated all day, even on sweltering steep climbs.





Sonorus features a fully removable electronic module. When your shell reaches its end of life, simply swap the electronics into a new one—ensuring no redundant cost and a lighter footprint for the planet.


Your ride isn’t just seen — it’s heard. Connect via Bluetooth to action cameras and capture real conversations in your footage.

Available in three sizes and four striking colors — engineered to match your head and elevate your riding style.

* Color selections will be collected via a survey after the campaign ends.
