I'm not convinced. Compare:

That was the best run in that video. The wheel spun less than 180 degrees after being carefully placed on the ground. In the original video the wheel was in contact with the ground for seconds before it got free to spin. It then spun for more than 180 degrees and seemed to be accelerating.

I know such motors are supposed to stop when you stop pedaling, but it could be a different one. There's still enough evidence to look damning.
