I recently brought a Kickr II.
It connects to my laptop through an ANT+ dongle. I cannot however get ERG mode to work.
I have read the posts which say that ERG mode should be selected at the bottom of the screen when you select workouts. No such option appears on my screen.
When I run Zwift through my iphone I can acess ERG mode.
I have a 4.0 Bluetooth dongle in the laptop as well however yet to try and connect through this.
I am running Windows 10.
