Wow, I don't get any "feeling" for this...
My bike is a collection of components. Maybe I haven't found the right bike (after 10 years?), but I think it's just that I can't ascribe human characteristics to a bike. And I rarely feel "at one" with my bike. Cycling pretty much feels like hard work all of the time, unless I am purposely taking it easy. Hard to feel "at one" when you are working hard. I like the feeling after the hard work. Accomplishment...
