Here's a pic of what I'd look like after trying to follow the guys on the OP video:





After commuting on everything from racing road bikes, randonneur bikes, hybrids, comfort bikes and mountain bikes (26" XC, 26" full rigid, and 29") I have settled on a "monster cross" bike for my primary commuter. It is essentially a 29" mountain bike designed around a fully rigid setup (no compensation for a squishy fork) and a drop bar. Sort of in the same vein as the Salsa Fargo.

Anyway, a few things I've noticed:

- I can keep a similar pace on a mountain bike as on a road bike (for commuting), and my point-to-point time is a wash regardless of what I choose to ride (including singlespeed)
- I have found that I enjoy the capacity of a mountain bike to accommodate a variety of tire sizes, from thin to fat.
- My penchant for IGH gearing means that I prefer a frame that s designed to allow for chain tensioning. This is not exclusive to MTB's, but the SingleSpeed frame design is where I find my sweet spot for options.

So my perfect commuter may not suit others, but I do think that MTB's offer great versatility (especially those designed around a fully rigid platform).

Have fun out there!
