I've had my PL-350 kit for a few months now. While the electrical components are working flawlessly, I've noticed a mechanical defect. The cassette is not properly aligned with the axle. The cassette wobbles about when the wheel is in motion. I know that some wobble is not uncommon and is usually not problematic. However in this case, the wobble seems excessive. Even after adjusting the gears, they never seem to align well enough. There is always gear chatter.
I have complained to my bike dealer about this problem. They tried replacing the cassette and tuning the gears, but the problem is still there. They've also told me that cassettes often wobble on their axles, but I haven't been able to find another bike that has nearly as much wobble. I suppose I should have a conversation with the bionx folks about this and see if there's a remedy. Has anybody else experienced excessive cassette wobble on their bionx wheel?
Yes, I've experienced that much wobble, and very bad shifting with motor hubs.
I've done some shopping for different cassettes with no luck. I've taken apart the freewheel
and tried adjusting it, but it actually worked better adjusted loose.
You might also experience a bit of noise from your cassette, and a bit of oiling helps a lot.

Is it really a cassette (slide on with lockring) or a thread on freewheel with integrated bearings?

It's really a threaded on freewheel? (-:
