Actually, I have had the same thing happen to me, though not as dramatically. On most of my rides I pedal under high-tension transmission lines, and I have noticed that, when I tap my fingers against the brake levers on my hybrid--havn't noticed this on the road bike yet--I get mild shocks. I have heard that high-tension transmission lines can create an electromagnetic field.
