Bryton Rider S810 GPS Bike Computer – 3.5" Touchscreen, 50-Hour Battery & Climb Challenge 2.0

The Bryton Rider S810 is the flagship GPS cycling computer in the Bryton range — stepping above the Rider S510 with a larger 3.5-inch colour touchscreen, a significantly longer 50-hour battery life, etched physical buttons alongside the touchscreen for reliable operation in wet or gloved conditions, and multi-satellite support (GPS, GLONASS, Galileo, BeiDou, and QZSS) for the most accurate positioning available. Available as a Device Only or as a Sensor Bundle including a Smart Speed Sensor, Cadence Sensor, and Heart Rate Monitor.

The 3.5-inch display is the largest in the Bryton range, providing more data fields on screen simultaneously and easier readability at a glance. The adaptive backlight adjusts automatically to ambient light conditions. Etched physical buttons alongside the touchscreen provide tactile control in rain, cold, or with gloves — a practical advantage over touchscreen-only operation in adverse conditions. Battery life of 50 hours is the longest in the Bryton lineup, with intelligent remaining battery estimation based on brightness settings. Like the S510, the S810 includes Climb Challenge 2.0 (real-time gradient and ascent data on any ride, not just preloaded routes), voice search in 100+ languages, automatic offline rerouting, and Virtual Ride simulation for indoor training. Preloaded OSM maps include cyclist POIs. It's compatible with the Bryton Gardia 300L radar for on-screen vehicle alerts, and supports Shimano Steps, Di2, and ANT+ LEV e-bike platforms. Data syncs automatically to Strava, TrainingPeaks, and Komoot via the Bryton Active App.

What It's NOT Good For

• Riders who want a simpler, lower-cost computer — the Rider S510, Rider 650, or Rider 550 are more appropriate at lower price points
• Waterproofing beyond incidental exposure — rated to 1 metre for 30 minutes; not designed for sustained submersion
• Back-to-Start or route retracing — not available on this model
• Cyclists who don't need the larger screen, longer battery, or physical buttons of the S810 vs the S510

Frequently Asked Questions

What is the difference between the Rider S810 and the Rider S510?
The S810 has three key hardware upgrades over the S510: a larger 3.5-inch display (vs 2.8-inch), a significantly longer 50-hour battery life (vs 30 hours), and etched physical buttons alongside the touchscreen for reliable operation in wet or gloved conditions. Both share the same software features: Climb Challenge 2.0, voice search, offline rerouting, Virtual Ride simulation, and Gardia radar compatibility. Choose the S510 if the 2.8-inch screen and 30-hour battery are sufficient; choose the S810 if you want the larger screen, longer battery, or physical button backup.

Why does the S810 have physical buttons as well as a touchscreen?
Touchscreens can be unreliable in wet conditions, with gloves, or when your fingers are cold — common scenarios for cyclists. The etched physical buttons on the S810 provide a reliable backup input method in adverse conditions, ensuring you can always control the device regardless of weather or glove use. This is a practical advantage over touchscreen-only computers.

What is multi-satellite support and why does it matter?
The S810 supports GPS, GLONASS, Galileo, BeiDou, and QZSS satellite systems simultaneously. Using multiple satellite constellations improves positioning accuracy, reduces time-to-fix, and maintains signal quality in challenging environments such as urban canyons, dense forests, and mountainous terrain where a single satellite system may struggle. This results in more accurate speed, distance, and route tracking.

Is it compatible with the Bryton Gardia radar?
Yes — the Rider S810 is compatible with the Bryton Gardia 300L Rear Light & Radar, displaying approaching vehicle alerts on the touchscreen so you can monitor traffic without looking behind you.
