If they're willing to misrepresent existing tech, it makes me wonder if they gave the full ceramic wheel an additional edge. Like, say... Lining the rim with weights to give it more momentum.

Yes it does seem a bit biased but I also have the same issue on my commuter bike, But not my road bike. I looked at the cones and the bearing combo and it appears as if my commuter bike has cheaper cones and bearings. It appears that my commuter has something like ABEC 3 bearings vs ABEC 5. It would have been better to tighten the cones to a known torque spec. Then spun up the wheels with an electric motor while monitoring the Odometer for miles and speed.
