As @mcneese.chad mentioned, we support Resistance mode for the Tacx Neo, but not Standard mode, regardless of whether you are connecting via Bluetooth or ANT+.
Fortunately, they offer very similar features! The main difference between the two is that Standard mode uses a sliding scale to adjust the set resistance of the trainer, and Resistance mode uses a percentage of the trainers resistance capabilities to create a set resistance mode. If you want to come out of Erg mode, Resistance mode is a great option!
