Wahoo ELEMNT MINI is the bike computer for those that want max data in a mini package! ELEMNT MINI comes with two connection options: phone free mode and phone mode. In both modes, the ELMENT MINI pairs seamlessly with the Wahoo RPM Speed Sensor included in the box, as well as other Wahoo heart rate monitors and cadence sensors. It works with our free ELEMNT Companion App that allows you to set up your data fields, customize profiles, track performance, and share ride data effortlessly - no more confusing menus! When in phone mode, the ELEMNT MINI gives you ride tracking, full ride data analysis, and call & text pop-up notifications. MINI is designed to work only with Wahoo sensors to ensure the connectivity – and in turn your ride experience – is absolutely flawless.
