name this bike

I watched a lady ride up to the paint store next to the diner we ate at this morning in Santa Cruz.  I ran across the street and took a couple pictures of her bicycle.  I remember reading an article written about these bikes in something somewhere, but I can't recall their name. 

 

check out the seat on this thing.  beautiful.

she seemed very comfortable and relaxed, almost tranquil.  It made me want to ride it.  If you know what these are called, please let me know.

ed. note:  Ed Jaramillo, a man who's virtues know no end, informed me it's a Pederson Bike.  Ed, hopefully one day, you will live in a state where people has some idea how to pronounce your last name.  Until then, I'll keep trying to teach them when we talk about you during your race.
