Why Smart Trainers Changed Everything
Smart trainers automatically adjust resistance to simulate climbs, intervals, and structured workouts. Paired with apps like Zwift, TrainerRoad, or Rouvy, they make indoor cycling engaging rather than soul-crushing. Power accuracy within ±1-2% means your indoor data matches outdoor reality. For the full indoor setup guide, see our indoor cycling setup guide.

The latest NEO features a redesigned motor for better road feel and new Motion platform for side-to-side rocking. Combines NEO 2T silence with KICKR v6-like movement. The most immersive indoor experience available.

Smart Trainer Buying Guide
Direct-Drive vs Wheel-On
Direct-drive trainers (KICKR, NEO, Suito) remove your rear wheel — better accuracy, less noise, no tire wear. Wheel-on trainers (Kinetic) keep your wheel — cheaper but louder and less accurate. If budget allows, always choose direct-drive.
App Compatibility
All trainers on this list support Zwift, TrainerRoad, Rouvy, and Peloton Digital. Wahoo and Tacx have the best app ecosystems. See our cycling computer guide for pairing options.
The Noise Factor
If you live in an apartment or train while family sleeps, noise matters. The Tacx NEO series is virtually silent. Wahoo KICKR is very quiet. Budget options are noticeably louder. Use a good mat underneath to dampen vibration.
