Vibration in the pedals when in under load?

I have a brand new NEO 2T (3 rides) that is doing this. Took my bike off my V2 KickR, put the Shimano 6700 10sp cassette on the NEO 2T (with 2 spacers) and I noticed the vibrations on the very first ride. They come and go, and they sort of feel the same as when I turn on road feel.

This was with the NEO 2T plugged into AC power. Are you all getting this with and without AC power?

Anyone every find a solution? Its quite annoying, my 5 year old Kickr is as smooth as butter.

I have this exact issue: low rumble, no sound, exaggerated when I crank with my hand. For some reason I don’t recall this issue/side-effect when the trainer was new. Have you tried difference bikes?

I want to buy NEO 2T, is this problem solved?

wha say garmin support ?

No

As I think I mentioned earlier, mine largely went away after changing my chain, I think the torque control may be over compensating from some drivetrain issues. That being said there is some small vibration there at lower speeds, I think this is just a side effect of the system design. It doesn't bother me anymore and I rarely even notice it.

I've replaced cassette, chain, lockings, spacers and the vibration never went away. I didn't notice the vibration during the first year of ownership and now its at the point where I don't use the trainer anymore. Its somewhat subtle and happens are lower cadence, but its bad enough that if I'm on the trainer for 30+ minutes by growing feels numb. 

That sounds more serious than mine, I know there were bearing issues at one point and sounds like yours needs replacing

I was under the impression that the bearing issue was audible. My unit sounds normal.
