The Wahoo Kickr CORE has features found in direct-drive trainers costing hundreds of dollars more: through-axle compatibility, maximum resistance of 1800w, 16 percent maximum simulated grade, a flywheel weighing 12 pounds and a power meter with accuracy within two percent. The Kickr CORE connects to devices via ANT+ and BTLE and can be controlled with Android or iOS—or from an FE-C enabled bike computer. Plus, it's so quiet. The Wahoo Kickr CORE is easy to set up: We had it unboxed and assembled with just a 5-millimeter hex wrench, and paired with our phone and laptop, in less than half an hour. Although we liked structured workouts in "erg mode"—setting a specific power target so the trainer could match resistance with effort—we were quickly hooked on the Zwift experience. When paired with a Wahoo Kickr Climb, we had more fun than we ever thought possible when cycling indoors.
