Pros and cons
Pros
- Touchscreen and buttons offer two ways to operate the computer while riding.
- Preloaded route maps and course creation support road, gravel and trail navigation.
- The built-in speaker can deliver prompts and the described bike-bell alert without relying solely on a paired audio device.
Cons
- The listed 12-hour battery figure is shorter than the advertised maximum in battery-saver mode, so real-world expectations depend on operating mode.
- Some training and connected features require compatible sensors, a smartphone or the Garmin Connect app.

What to know before buying
- Feature availability is conditional. Fueling prompts specify a compatible power meter and heart-rate monitor for the described use, while weather, road-hazard and group-ride features require a compatible smartphone and Garmin Connect app. Garmin Pay requires a supported bank and payment network.
- Customer feedback reports battery concerns and mixed app connectivity and ease of use. Consider those reported experiences alongside the advertised runtime and smartphone-dependent features.
Listing details to confirm
Battery claims differ by mode: the listing gives up to 12 hours for demanding use and up to 36 hours in battery-saver mode. The general battery field lists 12 hours, so do not treat 36 hours as an unconditional runtime.
