Expert opinion
KICKR CORE 2 keeps the same 1,800W maximum power, 16% gradient ceiling, ±2% accuracy claim and 5.4kg flywheel as the original CORE, with the update limited to WiFi, Race Mode’s 10Hz data rate, and KICKR Bridge sensor bridging. The flywheel is not motor-driven, so descent and negative-gradient simulation are not available. Independent testing found readings running close to Wahoo’s claimed accuracy once drivetrain loss is factored in, though results vary by drivetrain condition.

Hardware
- WiFi added; the original CORE had Bluetooth and ANT+ only
- New leg design, bolted to the frame rather than the earlier fold-out mechanism
- Weight down from around 18kg to 13.6kg
- Power accuracy, maximum power, maximum gradient and flywheel weight are unchanged at ±2%, 1,800W, 16% and 5.4kg
Software
- Race Mode transmits power data at 10Hz over WiFi, or Bluetooth on Zwift, up from 1Hz
- KICKR Bridge relays a paired heart rate sensor’s data through the trainer, freeing a Bluetooth connection slot on the controlling device
- Automatic firmware updates over WiFi

Features
KICKR CORE 2 runs through the Wahoo app. Full feature detail is covered on the Wahoo hub.
Zwift Cog and Click bundle
- Zwift Cog replaces the rear cassette with a single cog that fits any geared bike, removing the need to swap or index cassettes
- Zwift Click provides virtual gear changes and in-game menu controls from the handlebars
- Cog and Click work only with Zwift; the 11-speed cassette version is required for other platforms
Sensor bridging
KICKR Bridge relays a paired heart rate strap’s data through the trainer’s own connection, reducing the number of separate Bluetooth pairings a controlling device needs to hold, which matters most on devices such as Apple TV that support only two Bluetooth connections.
