Hello the photos are attached are of the Chaisecruzer or Bikeashaw at least until some gives me a better name for it.
It is an xtracycle /bakfiets missing link.
It is a single speed with tubeless 36" tires
wide custom hubs
3 disk brakes
14.5' feet long
3' wide
weight still unknown
Wheels courtesy of my Mt bike
This is the family's 3 rd xtracycle-ish bike and our fist bakfiets
It was built by us for the 2009 Burning Man for our transport and as a test platform.
Hope you all enjoy it.

UPDATE:
Hello John
I have been out in the shop tonight building the second rear hub for the 36" bikes.
It is going faster the second time as one wold hope.
There are some build photos.
Coker made the first wheels/tires in the 36" size.
My 36" Bikes use unicycle parts for rims and spokes.
When I built the 36" Mt bike there was one Al. rim and one steel as well a 2 tires on the market. Now there is 2 or 3 rims Al.on the market and 5 tires to the best of my knowledge.
The unicycle market is driving the products at this time. There are 13 or so 36" custom Mt bikes that I have seen photos of now.
The 3rd disk is on the front wheel , and the steering is done with 6 pulleys and one 5/16 cable. The two big pulleys were wheelbarrow rims cut down to just the center. The 4 small pulleys are for garage door cables.
If you look carefully I think all of those parts are in this photo.
I think that answers the questions you had. feel free to edit ask questions as you see fit. I did note that you did reduce / edit my dingle speed to a single speed. It however is a dingle, a bike with 4 sprockets that allows a change from a lower gear to a higher gear with out having much of a different chain length.
Tired now must sleep
