@shimceltic got it, my wahoo bike does a wee bit of that but non selectable.
No, your Wahoo (if it is a KICKR) has a REAL flywheel (that heavy round thing on your trainer
). The NEO has a "virtual flywheel" as the resistance is all done through electromagnetism and the neodynium magnets in the spinning disc/plate.
What
@shimceltic is referring to is "inertia" when going downhill. In the real world your wheel will keep on spinning, even if you stop pedalling, when going downhil. The same will happen on your KICKR, if you get physical flywheel up to speed, it will carry on spinning for some time and give you speed. The NEO simulates this behaviour when going downhill.
On the NEO however, if you turn off the wall power, the virtual flywheel and inertia will stop instantly and you will have to apply more power to keep the watts up. Therefore when on steep downhills, say -8% and more, it may be better to cut the wall power, as you can't apply enough power yourself without spinning at 120+ RPM.
