By design, the KICKR itself measures and transmits speed and power data. New KICKRs (not including the KICKR SNAP or CORE) also come with our RPM / Cadence sensor included.
Update: As of Sept. 4th, 2019, KICKR '18 models running Firmware v3.4.69 or newer and KICK CORE models running Firmware v1.0.11 or newer now support automatic cadence tracking and broadcasting over both Bluetooth and ANT+.
Additionally, other Bluetooth 4.0 (or newer) and ANT+ sensors can be paired with the Wahoo Fitness app. For heart rate, we recommend our TICKR heart rate monitors (not included).
