Bryton Rider S810 3.5in Color Touchscreen GPS - Long Battery Life

Our review of the Bryton Rider S810 finds it is best suited for endurance cyclists and route-focused riders who need a clear display and long runtime. The single biggest reason to consider the S810 is its combination of a large 3.5in color touchscreen with an adaptive light sensor and an industry-leading 50-hour battery life, which together keep data visible and the unit running through multi-day rides or long training sessions without frequent recharges.

Key Features

• 3.5in color touchscreen: The larger screen with slimmer bezels makes data fields easy to read while riding and works across a wide range of lighting thanks to the adaptive light sensor.
• Enhanced grip and etched buttons: Etched buttons improve anti-slip control so riders can operate the device confidently in wet or rough conditions.
• 50-hour battery life: Extended battery runtime supports long outings and the device estimates remaining hours based on brightness to help manage power use.
• Climb Challenge 2.0: Real-time climb prediction provides unlimited climbing data for routes you discover, giving useful ascent metrics even without preloaded segments.
• Turn-by-turn navigation: Preloaded maps show road names and distance-to-turn, and the unit recalculates routes without a phone connection when a turn is missed.
• Broad connectivity: Bluetooth and ANT+ support a wide range of sensors and platforms, and the Bryton Active app auto syncs rides to services like Strava, TrainingPeaks, and Komoot.

Who It's For

The Rider S810 is ideal for long-distance cyclists, bikepackers, and serious commuters who prioritize screen readability and battery endurance. Its offline navigation and real-time climb data make it useful for riders tackling varied terrain who want climbing insights without relying on a phone.

Casual riders who want a very simple bike computer or those who prefer a minimalist non-touch unit may find the S810 overfeatured for their needs. Riders who expect flawless connectivity in every situation should note that some users report mixed functionality with certain features or sensors, so advanced users who need absolute consistency may want to test compatibility first.
