For context, the similarly priced Wahoo Elemnt Roam claims around 17+ hours, while Garmins outgoing flagship Edge 1050 pushes past 20 hours, albeit at a steeper 553 price tag (currently reduced by 8% on Amazon UK).I recently covered Garmins latest release, the Edge 1060, which replaces the 1050 as the most expensive bike computer on the market at an eye-watering 963. Although we have yet to publish our full review, its headline specs including a built-in microphone and speaker for voice control suggest it will be the best of the best if you're after Garmin's latest tech.
