Smart Trainer Control Modes for KICKR, CORE, SNAP, or BIKE

Wahoo trainers including the KICKR BIKEs, KICKRs, KICKR CORE, and KICKR SNAP can be used in three different resistance modes: ERG, Level, and Passive, as described below.


Accessing the Resistance Modes on your Wahoo Smart Trainer:

  1. From the main screen of the Wahoo app, select Record tab in the bottom center.
  2. On the Record screen, select the Profile button in the bottom left corner.
  3. Select Indoor Cycling.
  4. Select your preferred resistance mode from the tabs across the top of the screen.

Once in the workout, changes to trainer control can be made on other workout pages by using the Control button in the bottom right corner.

Differences Between Modes:

 Each mode provides a different kind of resistance, as described here.


Our personal favorite - intervals have never been easier (or harder)! Set your desired power and watch as the KICKR adjusts to keep you honest during training. If your cadence drops, the KICKR will increase the resistance to maintain a constant power output, regardless of speed. It's the ultimate way to train - with power! Click here for more info.



With Level mode you can modify the nominal grade in .5% increments and the app will provide  resistance accounting for your weight as entered into your profile to simulate riding that grade outdoors.  When using this mode, ensure your weight and tire size is properly set in the KICKR's sensor details for accurate power calculations.



In Passive mode, the Wahoo app can connect to multiperipheral trainers (KICKR v4 and later, CORE, and BIKEs) and passively record your output when completing your workout in a third party app (Zwift, TrainerRoad, Rouvy, etc).
Note - SYSTM workouts are already present in, and Zwift rides can now be uploaded to your unified Wahoo activity history.  Speed/distance as recorded in the Wahoo app may also differ from what is recorded in the 3rd party app as it may be calculated differently, based on power, etc.


*When riding in ERG mode you may notice that speed doesn't seem to relate to your power output or gearing. This happens because ERG mode is designed to maintain the target power at any wheel speed or cadence.  The speed recorded will fluctuate based on the gear and cadence you have selected, and may not be accurate. You may need to try different gears to find which is closest to your desired or expected speed.


Additional ERG Settings:

Accessed through the trainer's sensor details

ERG Mode Speed Simulation: This setting simulates speed based on power input for greater accuracy of speed data. Enabling is a personal preference, will not impact overall trainer functionality, and not required (most who train with power are not concerned about speed data).


ERG Mode Power Smoothing: this setting enables smoothing reported power to eliminate small inconsistencies in pedal strokes, making power graphs appear less erratic. Enabling is a personal preference, will not impact overall trainer functionality, and not required.
