Flywheel on Smart Trainer

ruko

Tacx Neo2T specs say it has a 125KG flywheel. 125,000Grams is about 275 pounds. It must be a virtual flywheel? How does this work? I can't imagine turning over a 275 pound flywheel virtual or otherwise.
Thanks.

Seeing as the turbo weights about 47lbs then yes it's a virtual flywheel.

So how does a virtual flywheel work?
