I wrote a little about the Steinlauf family on my website:

Those articles were given to me by a Chicago old-timer. He didn't know anything about it. Even though I roamed the streets of Chicago for eight years looking for freakbikes, and hearing about and tracking down old freakbikes (I mean that's what the website is about), I never heard or found any evidence of them. But in a city of 3 million people, who knows? I was always surprised by the bikes I ran across.

If you click the link you can see more pictures and read an article about them.
