I thought you wanted to reduce the unsprung mass on a motorcycle; that rear wheel looks really heavy. Looks difficult to service/change tires too.

That is a good point when discussing vehicles that dont usually use hub motors, like electric motorbikes do anyway. I would much more critisize the spokeless design that is for sure based on an bunch of expensive and even worse, proprietary parts.

I was always under the impression that large bearing surfaces are much less efficient than small bearings in large wheels. It’d be neat if they figured out a maglev style bearing, but I think cold supercontuctors would be required
There is a lot more friction surface, which is why we’ve never really reinvented the wheel.
