We use the Edge 1040 Solar GPS Bike Computer to make the most of our time on two wheels because it's the only solar-charged option from Garmin, positioned right at the top of the line. Even during the most demanding usage--including GPS tracking and connectivity with other devices--the solar charging allows this computer to run for up to 45 hours straight. With more conservative usage, this model can run for upwards of 150 hours. Our favorite features include the multi-band that lets us explore far outside of cell service and the three included mounts that let us move the device from our mountain bike to our road bike with ease. The Edge 1040 also uses stamina insights and training suggestions to help dial us in for bigger efforts and race days.
