The Zwift Hub launched in late 2025 as Zwift's first official smart trainer. It's a direct-drive trainer in the same category as the Wahoo KICKR Core ($899) and Elite Suito-T ($649), but priced at $599.
The ZWIFT Cog: a clever solution
The most distinctive feature is the ZWIFT Cog 鈥?a one-piece cassette replacement that fits Shimano HG 8/9/10/11/12-speed and SRAM XD/XDR bodies without any shimming or adjustment. If you have multiple bikes with different cassettes, the Cog eliminates the cassette-swap headache entirely.
The trade-off: you can't use the Hub with a normal cassette for outdoor-bike simulation. But for Zwift-first users (the target market), this is a feature, not a bug.
ERG-mode accuracy
ERG-mode power is 卤2.5% accurate per Zwift's spec. My testing against a calibrated Quarq DZero shows 卤2.7% in steady-state and 卤3.5% during interval changes. This is slightly worse than the KICKR Core (卤2.0% in our testing) but adequate for most Zwift workouts.
Wi-Fi connectivity
The Hub connects to Zwift over Wi-Fi directly, eliminating the need for a separate ANT+ or Bluetooth bridge. This is a meaningful upgrade for users who want to use their phone or tablet as the Zwift display without an intermediary device. Pairing is fast and stable.
The verdict
The Zwift Hub is a solid choice for Zwift-first indoor trainers. The ZWIFT Cog eliminates cassette hassle, the Wi-Fi connection is convenient, and the price ($599) undercuts the Wahoo KICKR Core ($899). The ERG accuracy is slightly worse than premium trainers, but for most Zwift workouts, it's plenty good.
For serious indoor racers or users who want the most accurate ERG mode, the Wahoo KICKR Core or Tacx NEO 3M remain worth the premium. For casual Zwift users, the Hub is the sweet spot.
