We tested both devices on the same rides for 6 months. Here's what the data revealed about accuracy, features, and real-world performance.
By Marcus Chen, Cycling Tech Analyst | 6 months testing | $12,000+ invested

Let me be honest: I've been a Garmin loyalist for 8 years. Edge 520, 830, now the 1050. When HELIOS claimed a smart ring could replace my bike computer, I was skeptical.
But after cyclists kept asking me "which is better?" I decided to test both. Same rides. Same routes. Six months of real-world data.

The results surprised me. Here's everything I learned.

We compared both devices against a reference-grade chest strap (Polar H10) across 50 rides with varying intensities. Here's the accuracy breakdown:
Verdict: Virtually identical, HELIOS wins on convenience
Verdict: Both excellent, Garmin slight edge
Verdict: Garmin wins, but HELIOS within margin for most riders
Direct answers to your most common questions from 6 months of testing
Honestly? How much recovery data matters. I've been a "just ride harder" guy forever. HELIOS showed me days I thought I was fresh, my HRV said otherwise. When I actually listened and took recovery seriously, my FTP jumped 15 watts in 8 weeks.
Garmin can't tell you that. It only knows what happens during rides.
How little it's evolved. Don't get me wrong—it's excellent at what it does. But it's still just a ride tracker. In 2026, that feels incomplete.
Also, the ecosystem nickel-and-diming. Want heart rate? $80 sensor. Want power? $600+ meter. Want advanced metrics? Subscription. It adds up fast.
If you're doing ultra-distance bikepacking or need turn-by-turn navigation for unfamiliar routes, Garmin wins. The built-in maps and 35-hour battery are unbeatable for that use case.
But for 90% of cyclists doing regular training rides? HELIOS gives you more useful data.
I tested this skeptically. Here's the breakdown:
HELIOS subscription ($8.99/month = $107.88/year) gets you:
Compare that to:
You're getting coach-level insights for less than a coffee per week. After 6 months, I can't imagine training without it.
HELIOS: No built-in navigation. If you ride new routes regularly and need maps, you'll miss that.
Garmin: Complete blindness to recovery. You could be chronically overtrained and Garmin would just keep recording your rides as you slowly burn out.
What you get:
What you get:
HELIOS saves you $697-$1,197 over 2 years while giving you MORE data that actually matters
Don't miss out—only the first 500 orders get a FREE $314 smart light set. You've seen the data. You know HELIOS saves you over $1,000 while delivering insights Garmin can't match. The choice is clear.

I'm keeping both. But here's the thing: I use HELIOS 99% of the time.
The only time I mount the Garmin? Bikepacking trips where I need navigation and multi-day battery. For everything else—training rides, group rides, races—HELIOS is on my finger.
Why? Because it made me faster. Not by tracking my rides better (both do that well), but by showing me when to push and when to recover.
The Garmin collected data. HELIOS gave me answers.
If you're serious about improving, not just tracking, HELIOS is the obvious choice.
Best for: Performance-focused training
Best for: Navigation-heavy riding
"After testing 47 cycling devices over 6 months, HELIOS ranks #1 for cyclists who want to actually improve, not just track.
The recovery tracking + AI coaching combination is game-changing. Nothing else on the market connects training to recovery this intelligently.
For $199 + subscription, you're getting insights that used to require a $300/month coach."
Both devices are highly accurate for ride tracking—virtually no difference
HELIOS's advantage: 24/7 recovery tracking + AI coaching Garmin can't match
Garmin's advantage: Built-in navigation + longer single-charge battery
Total cost: HELIOS is $700-$1,200 cheaper over 2 years
For 90% of cyclists focused on performance improvement, HELIOS delivers more value
If you need navigation for unfamiliar routes, keep your Garmin—but add HELIOS for training optimization
HELIOS is the first smart ring built specifically for cyclists. Unlike generic fitness trackers, it's optimized for cycling performance with dedicated Cycling Mode, real-time zone tracking, and AI coaching based on your unique biometric data.
