The battery figure nobody else matches
Bryton competes on specification, and one specification in particular.
The Rider S810 GPS computer.
Battery life. Fifty stated hours against sixteen for the Garmin in the same hub. A day ride never troubles any of these units; a four-day tour with no reliable charging does. Fifty hours means the computer is not the thing you are planning around.
Screen size. Three and a half inches is the largest in this catalog, with offline European mapping, which is excellent for a map.
Features that need no preparation. Its climb prediction works from map data as you ride rather than requiring a preloaded route.
Sales position and ecosystem. Rank 15,141 against the Garmin’s 520, and the surrounding software and accessory ecosystem is smaller.
Treat fifty hours as a best case, as with every battery claim — navigation with a bright backlight is not the measurement condition.
And measure your handlebar space. Three and a half inches is a lot of screen next to a light and a phone mount.
The S810 was not listed on the US market when we checked.
3.5" touch · 50 h battery · offline Europe map · ANT+/BLE
The longest-running computer here by a wide margin — fifty hours stated — with a 3.5-inch touchscreen, offline European maps and turn-by-turn navigation.
Best for: Multi-day touring and long events where charging is inconvenient and the map has to work offline.
