Wahoo KICKR CORE 2

The safe middle choice for most riders, especially Zwift regulars. Wahoo rates it at plus or minus 2 percent accuracy, 1,800 watts and 16 percent grades, and this generation adds Wi-Fi, a race mode and Bluetooth bridging for sensors. You can buy it with an 11-speed cassette or with a Zwift Cog and Click for the same price; the Click's virtual shifting is officially supported only in Zwift, so take the cassette if you train elsewhere. One in-depth review called it essentially silent, with a fan louder than the trainer. List price is $549, and it has been on sale for $399. There is still no carrying handle.
