I remember trying to figure out what a hybrid is when I was looking to buy my first bike in decades a few years ago and getting confused. When I quit riding after college, there were 10 speeds, three speeds and the Stingrays most of us had as kids. When I looked again the 10 speed was now 27 or 30 speeds, three speeds were gone, and mountain bikes had entered the picture. I could relate to all of those, but the hybrid was a lot harder to describe.
