I was reading about different mini pumps, and I found this helpful video of a dork on a recumbent changing a flat.
I like so many things about this guy. He's supposedly out for "exercise" but then seems to spend an awful lot of time coasting, he has two mirrors on his bars and another on his "eyeglasses," his bike has a battery (could be for a lighting system, but I'm going to bet it's a powered air-horn), and he doesn't know how to use a patch kit.
Oh, and the helmet-cam, obviously. Amazing.
