$29 for one year
A coverage plan designed to protect your brand new HELIOS ring. It sits on top of the 1-year manufacturer warranty that comes free with every ring — that one only covers faults, not accidents.
Drops, dents, scratches and crash damage are all covered. Tell us what happened and we replace the ring, once per year.
If the battery stops holding a proper charge, that's covered for the whole plan.
Start a claim in the app and we send a replacement ring out to you.
*We pay the postage both ways on the 2-year plan
Losing the ring isn't covered. If it goes missing or is stolen, you'd need to buy a new one.
I was stuck at the same FTP for 8 months. HELIOS showed me I was overtraining and needed more recovery. Within 6 weeks of following the AI coach, I gained 15 watts and finally dropped the guys who used to drop me.
Between work and family, I only get 6 hours a week to train. HELIOS tells me exactly what workout to do each day based on my recovery. No more wasted rides. Every session counts now.
I used to second-guess every training decision. HELIOS gives me confidence that I'm doing the right thing every single day. My trends caught overtraining before it became an injury. Game-changer.
Sensitive skin made every long ride miserable with a strap. HELIOS reads within a couple bpm of my old Polar on intervals, and I forget it is even there. Wish I had switched a year ago.
Marco kept me from blowing up at the wrong moment three different times across 28 hours of riding. The fueling reminders alone earned back the subscription. I rode sharper than ever.
I followed the plan Marco built for the full 90 days and set PRs on three different climbs. The plan adapted every week based on what the ring saw. No marketing claim — just my own data.

One 3–4 g ring does everything your current pile of devices and subscriptions does — for a fraction of the price.
Trained on the science, built around your data — here’s what you reach for every day.
Navigation, climbing, live metrics and more — no handlebar full of devices.
Marco turns every session into a precise fuelling plan — exact carbs, fluid and timing, before, on the bike and after. No apps to wrangle, no maths.
Pair once. After that the phone takes care of the rest — readiness in the morning, live metrics on the ride, the long view on Sunday. We didn't add a single dashboard you have to learn.
We don't hide the 3 and 4-star reviews. Every review here is from a verified buyer who has worn HELIOS for at least 14 days.
W e started THRIVE because we were tired of riding with a watch, a chest strap, a cycling computer, a recovery app, a sleep tracker and a coach we never had time to call back. Three of us are cyclists. One of us is a sports physiologist. All of us were drowning in data that lived on six different screens.
HELIOS started with a question: what if the sensor disappeared, and the coaching showed up where you actually live — on your phone, in your morning, on your ride? Eighteen months later, this is what we shipped. A 2.4-gram titanium ring that catches every signal a chest strap catches. A platform that turns those signals into one number you can act on. And a team of coaches and sports scientists sitting behind the AI so it never feels like talking to a robot.
We can't promise HELIOS will turn you into a Cat 1 racer. We can promise it will give you back the brain cycles you spent juggling devices, and replace them with a clearer answer to one question: how do I ride better tomorrow than I did today. That's all we set out to do.
This is launch pricing for the HELIOS ring. You're not just buying a ring — you're joining the first group of riders shaping what we build next.

From the first night, HELIOS learns your resting HR, HRV, sleep and SpO₂.
Marco spots what you absorb and what quietly drains you. The guesswork ends.
Sessions start tuning to how you have actually recovered — not a generic calendar.
Every ride, fuelling and rest day is built around the real you.
Ninety days. One goal — yours. Tell Marco what you're chasing and he builds the plan that gets you there.

HR tracking is within 2bpm of my old chest strap in every ride — including a 4hr threshold day. Best thing I’ve bought for cycling this year.
Cancelled two other subscriptions. Sleep tracking is more useful than my old ring because Marco actually says something with it.
Hardware is excellent. Knocking a star because pairing took two attempts. App could also use a way to silence Marco for a day.
Marco flagged three days of suppressed HRV and recommended two days easy. I ignored him, did the threshold workout, blew up. Now I listen.
The product itself is 5 stars. Knocking it down because the monthly locks the features I bought it for. Should be clearer upfront.
Sensitive skin made a chest strap hell on long rides. This replaces it and reads within 1–3bpm of my old strap on intervals.
Said 7–10 day battery. In −8°C I got closer to 5 days. Otherwise excellent — would buy again. Wish the marketing was clearer.

Followed the plan Marco built for the full 90 days. PRs on three climbs. The plan adapted weekly based on what the ring saw.
