This past summer I was unlocking my Earl from a bike rack. A kid no older than 11 or 12 walks up to me and asks "where are your gears?" I replied with "my cog is right here," and I pointed to the rear wheel. He was confused. He then asked again; I told him that I ride a single speed. "There's only 1 gear; it's actually quite fun. Also, you can't coast." That confused him even more. He then said that my bike was stupid so I rode off.
Sigh.
