We buy or borrow, ride for weeks, and score on accuracy, noise, road feel and app support — not on who sent us the free unit.

Best-in-class specs (2300W, 24% gradient, ±1% accuracy) plus side-to-side movement, full connectivity (WiFi/Ethernet/Bluetooth x2/ANT+), the ability to run without mains power, and per-pedal-stroke analysis with a 3-year subscription included.

Best-in-class accuracy, every connectivity option available (BT x3, ANT+, WiFi, Ethernet), a 10Hz 'Race Mode', and Wahoo's EasyRamp feature to ease back into resistance after stopping mid-interval.

Class-leading accuracy, a virtual flywheel that simulates different road surfaces, and built-in multidirectional movement for a more natural pedal stroke. No calibration needed, ever.

Takes the Kickr V6 and mounts it on an 8-inch rolling track, letting the whole trainer slide forward/back and rock side-to-side — noticeably more comfortable on long sessions.
