Social Tandem Made From Two Basman Bicycles

I purchased two Basman bicycles from Ruff Cycles in Germany, altered one of them to be a straight bar frame, turned the other into a step-through, then welded them together into a social tandem. I made it so that my wife and I would no longer get separated during group rides. The last thing to work out was the Ackerman steering, which I had to re-work a couple of times, but I got it.
