Rubber side down
 

It's in the rules.
Velominati ? The Rules

Is this a bmx'er thing?

I think the "rule" is about the practice of tuning one's bike and adjusting derailleurs upside-down.

I've seen people park their bike without a lock upside-down at stores, apparently thinking that a thief wouldn't be smart enough to turn it right-side-up, and ride off.

Yesterday I saw an unlocked Magna with the front wheel turned 180 degrees, again assuming a thief wouldn't be capable of turning the bars forward and riding.

They didn't think I was serious, when I reminded them of the rules.

Always hate to see one of the nice saddles getting rashed in that position.

I will admit that I'm an upside-down bike mechanic (tinkerer).
But, I always try to find a soft place to invert the bike.

It's okay to invert BMX bikes. BMX bikes are stable upside down and road bikes are not. Cable housings don't get damaged by inverting BMX bikes. BMX bikes rarely have saddles that are worth worrying about.

Only time I turn any of my bikes upsidedown is with a towel on the floor to protect the saddle, and for adjusting the below chain stay "U" brake on the Rockhopper.

I work on my single speed bikes upside down. I find it much easier, especially wheel installs and chain adjustments.

My work area is carpeted, specifically for this reason.

Yeah but then you get a discount!

I'll do it Pasadena Style on grass, a towel or carpet. It is much easier to change a flat this way than leaning the bike on your shoulder.

What is the cargo/tandem looking bike in the back?

Based on the logo, it appears to be an XtraCycle

And, a factory built bike, not an add-on kit.

My father taught my how to change a wheel just like this, and that's the way I've done it ever since. If you don't have a workstand, this is the next best thing. In fact, this is the best technique to make sure the axles are seated in the dropouts correctly.

I believe it's a Surly Big Dummy.
Set up for kids to ride on the back.

It's pretty nice.

Edit to add.

I'll have to ask, the bike belongs to my LBS owner Aaron Goss.

I know it's a Surly, but it could be an Xtracycle conversion.

Is this considered Drewing,
when you do this to a Colnago?
