Edge 1040 Solar is powered by the sun and packed with everything under it. It's our first GPS bike computer with solar charging and multi-band GNSS technology, so you can ride longer and get even better coverage under dense tree cover or the urban canyon. The Edge 1040 Solar bike computer also has performance features that help you understand your strengths and weaknesses. When paired with your compatible sensors, it can even help you manage your efforts by providing power targets throughout a course and stamina feature insights, so you know how much gas is left in the tank. And the setup is simple, so you can take it out of the box and be out riding in no time.
