Garmin's new Edge 540 Solar Cycling Computer is a must-have tool to help us improve our riding, and it's so awesome that it uses solar power to do so. With solar charging, we can ride longer and harder without our computer crashing mid-ride and taking away the incredible features the Edge 540 provides. When used with a heart rate monitor and power meter, we can see our most accurate data, which the computer uses to create personalized workouts, adaptive coaching, and live power targets. Riding longer may come with unknown routes, which is never an issue while using the Edge 540, thanks to multi-band GNSS technology and pre-loaded route options.
