What Our Gearhead® Experts Are Saying: "I’ve put hundreds of hours on the KICKR CORE and it’s rock solid. The ride feel is smooth and surprisingly realistic, power accuracy stays tight, and the flywheel is impressively quiet. Setup is quick, app connections are painless, and pairing it with CLIMB or HEADWIND turns winter training into something I actually look forward to." We count on the KICKR CORE Smart Power Trainer when structured training, winter weather, or late-night rides call for an indoor setup that feels as close to the road as possible. Wahoo built this trainer around a quiet, beltless flywheel and refined algorithms that deliver a smooth, consistent ride feel with power accuracy within +/- 2%. Whether we’re grinding through intervals or spinning easy, the CORE responds instantly to shifts in cadence and resistance. Its steel frame stands firm when we’re laying down big watts, and the direct-drive system saves our tires while providing a stable, secure connection for focused training. LED indicators make pairing simple, while broad connectivity—ANT+, ANT+ FE-C, and Bluetooth—lets us link the trainer to virtually any app or device. Compatible with KICKR CLIMB and HEADWIND, it transforms indoor riding into an immersive, responsive training environment designed to push fitness forward.
