The Monster Bike (project)

Here's my latest project.
So I found these two SUV tires by a dumpster...
Then I asked a local tire shop if they had some 'damaged' 16 inch rims to fit them...
Today, I layed out some parts on the driveway, then climbed up onto the garage roof to take a picture of the mockup...

This is the result.

If this thing ever gets built, I think it will be the first ever SUV-tire-shod tallbike.
If anyone knows of another example, I'd love to see it, but I haven't found anything like it in my online 'research'.

Ideally, it will have all-wheel-drive, and 3 shifters (crank, rear wheel, and an intermediate shifter to select a high (cruising) range and an ultra-low 'offroad' range. It's gonna be tremendous!

I have no idea what to do for brakes. Maybe some sort of spoon brake, or a customized cantilever brake that acts on the rim, or maybe discs... Or a drag chute?
