I was surfin’ around and I found this image from Blonde Fabrications. A 36-inch-wheeled mtb. Appropriately named the Amazon Blonde 36er, the builder apparently races it too. I’m sure it handles like a tank, but I love it when people are willing to push a concept (in this case, 29er wheels vs the standard 26 mtb wheels) to the extreme.
When you look at this picture, keep in mind that the my whole bike could pass thru the rim if it were not for the spokes.
