Here goes with my re-"but..."-L's:
But, my seat doesn't actually hurt me, because my bike is set up so there isn't any pressure on my crotch, and certainly no junk ripping harness when I fall.
But, I can get going as fast as you do on your video on my mountain bike with big tires.
But, I can't lift it up into my apartment
But, where do I get parts? Tires? Service?
But, I like that bikes can go pretty much anywhere
Okay, I'd still love to ride one and see what it feels like. I'm a sucker for 2 wheels and gears.
