The power line is surrounded by a powerful magnetic field that may somehow induce a charge either in the bike or rider. Perhaps when you dismount or if the tire is wet some transmission to the ground occurs, or perhaps the charge can jump the inch from the wheel rim to the ground. I'm speculating here, and hope to get some electrical engineer's opinion at some point.
