Battery life extended by solar charging
If you're serious about cycling you need a cycling computer but if you're really serious, the Garmin Edge 1040 Solar bike computer is the one to consider. It features Power Glass solar charging that extends battery life up to 42 minutes per hour for up to 100 hours total in battery saver mode. In demanding use cases you get up to 45 hours of battery life. The device uses multi-band GNSS to get accurate GPS positioning no matter where you are whether in cities among high rise building or among tall forest trees.
A 3.5 inch touchscreen display shows you everything you need including stamina insights, power guide, cycling ability, dynamic performance monitoring, training status, targeted adapted coaching, intensity minutes, heat and altitude acclimation, nutrition and hydration alerts, and more. It can even track mountain biking metrics like jump count, jump distance, and hang time. It can also display upcoming forks in the trail in context of where you are and provide turn-by-turn directions.
