That's a great point. I hadn't really thought about where you'd ride them.

Yea, but on the other hand it's not going to tip over very easily.

It's for street riding. That way you get the whole lane but can ride on the inside.

Jokes aside, if this was a quick attach/release scenario, you could ride somewhere with someone, drop them off, hook the bikes together and bike away.

Of course, a traditional tandem could do the same and wouldn't be 6' wide or whatever. You'd probably look a little odd riding a tandem alone, but I'd take that over this setup.

In reality, I’d like to see a bike rack that could support this stupidity…

Another great point...how would you transport them? Maybe the poles do come off somehow. He's local to me, maybe I should go check it out in person!
