Smartwatches are a great way to record your bike rides, with many featuring built-in heart rate monitors and the ability to connect to ANT+ and Bluetooth accessories such as power meters.
While they’re not as specialised as bike computers, their versatility means they can be used on or off the bike – whether that’s checking health metrics or tracking runs and hikes.
There are different types of smartwatches, with slimmer and lighter designs typically catering more toward data capture, while larger designs usually feature navigation.
