- Level: Choose your power curve! Just like riding on a fluid or wind trainer, the faster you go, the harder it gets. The level you select determines the progression of your power curve.
- Resistance: Just like adjusting the brake in spin class. For those who need complete control, this allows you to set the resistance of the brake manually anywhere from 0 to 100%. Regardless of speed, resistance will remain the same until otherwise changed.
- Erg*: 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!
- Sim: With Sim (AKA Route) mode, enter your weight, bike type, riding position, headwind, and grade to have the KICKR accurately model the power curve as if riding outdoors. When using this mode, ensure your weight and tire size is properly set in the KICKR's sensor settings for accurate power calculations.
The below video demonstrates how to get to the KICKR control page within the Wahoo Fitness app to use each different mode.
*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.
EGR Mode Speed Simulation, is a simulated speed based upon the power you put into the trainer. This setting is personal preference and will simply result in greater accuracy of speed data. This setting is NOT required to be enabled (Most who train with power are not concerned about speed data). This will setting not impact the functionality of the trainer.
Erg Mode Power Smoothing, is a setting in the Wahoo Fitness app that allows you to make the reported power very smooth and doesn't allow it to show small inconsistencies with a user's pedal stroke (this makes the power graph less busy). This will setting not impact the functionality of the trainer. This setting is personal preference and will not be required to be enabled.
