The walking bike. Help.

splatbucket surely all you need would be a steel bearing that would be the right width, something cheap off a piece of machinery, then a small piece of pipe which you could solder the 'legs' to then slot the bearings in and viola. think like a skate wheel but metal, I'm guessing it doesnt have to be ridden 100's of miles

Actually even a skate wheel forced into a steel tube of the right diameter would do the trick.

Going even further, if this is for a photo shoot would the wheels/bearings/bike even have to be functional ?
