The hubless motorcycle - wheels with no spokes - video

This amazing motorcycle has wheels without any hubs, or spokes. Hubless wheels work by fixing the rotating parts (brake ring, bearings, hubless rim) onto the outer side of a non-rotating inner ring that attaches to the motorcycle’s swingarm or forks.

Advantages include decreased unsprung weight, reduced structural stress (no spokes to transmit forces through), increased braking leverage, more accurate steering, reduced vibration and a lower center of gravity.

However I wonder if ride is harsher as spokes usually provide a degree of flex smoothing out the bumps and holes. I don't see this as anything more than a design exercise, so its a high novelty value, but low practical value.
