The biker boys at Amen Design have built a chopper based around Franco Sbarro’s hubless wheels. And it really rides!
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. Hubless wheels also look bitchin’, which, we’re guessing is the main motivating factor in Amen’s decision to use them.

Look ma no spokes!
Who’s going to be the first person to try to dive through the wheel while it’s moving?
“reduced structural stress (no spokes to transmit forces through)”
This is nonsense. The forks still see all the weight the whell sees - period.
I was thinking the same thing, I am positive Billy Lane was doing this years ago.
There is almost no stronger way to biuld a wheel than with spokes...What buffoons.

wouldn’t setting the forks that close to the bottom of the wheel REALLY screw up the steering/ handling?
OK, how do you change the tire and how long will it take to change?
Accept for all the other ways, right? Or are you talking about its strength versus its weight?
“wouldn’t setting the forks that close to the bottom of the wheel REALLY screw up the steering/ handling?”
Not sure how the handling would be affected, but there’d be much greater danger from road debris. Imagine snagging the forks on rocks or potholes instead of just riding over the bumps like with a normal wheel. It looks pretty cool, but I’ll definitely defer to others to do the beta testing.
In Obamaworld, it must be changed through Government, and with great haste.
That rear tire is bizarre.
There is still a hub but the hub is fatter and has a hole in it.
The spoked wheel is closest to a pure "tension / compression" stress loading with very small bending moments due to the left / right "overlap".
Even the "solid" fat boy type wheel design is not stronger, when matched for weight.
