Here’s a link to some Ultimate Wheel Cokering.

Me and a lot of other people have tried valiantly to ride Mackenzies Ultimate coker.

Me too, after about five minutes. Of course I can barely ride a regular one. I have seen Tom Miller (Unicycle Factory) ride an “ultimate” wagon wheel, about 46" diameter and probably 40 lbs, many years ago. Talk about putting your crotch at risk!

Here’s a short vid I took of a huge ultimate wheel at OUI05
(i think it’s Brian Mackenzies)
