By design, the KICKR itself measures and transmits speed and power data, and now with KICKR '18 or KICKR CORE updated to the newest firmware, also calculates cadence. Because of this, new KICKRs no longer come with our RPM / Cadence sensor included.
Additionally, other Bluetooth 4.0 (or newer) and ANT+ sensors can be paired with the Wahoo Fitness app. For heart rate, we recommend our TRACKR heart rate monitors (not included).
