Enhanced power accuracy to provide accurate power measurement of +/- 1% and generate up to 2200W of resistance. Through an automatic calibration process, KICKR continuously offers accurate and precise power without a manual process by the user. KICKR features a 16lb flywheel specifically engineered to provide riders with a more precise inertia needed to recreate an outdoor ride feel while training indoors. The belt motor drivetrain on the KICKR was designed specifically to provide a smooth and virtually silent riding experience. When connected to your smartphone, tablet or computer, KICKR automatically sets your resistance via your favorite app or software. The KICKR flywheel is innovative and proven technology that emulates the power and inertia experienced during outdoor riding. It provides the most realistic ride feel especially when using virtual riding/training platforms like Zwift, The Sufferfest, and Trainer Road. The resistance of the KICKR automatically adjusts to simulate climbs up to a 20% incline. ANT+ and Bluetooth capabilities allow it to connect to both smartphones and GPS devices simultaneously or separately. An ANT+ FE-C connection allows the KICKR to be controlled from any FE-C enabled device or application.Robust steel construction ensures the KICKR stays in place while you crank out the watts and stands up to years of heavy use.
