Mobile phones aren't the only things that can do that...
This was on my roadbike and although I did just come down a pretty steep hill, I doubt I was going that fast. |8^)
I believe this to have been caused by a traffic sensor coil. I pass them all the time. Those things are pretty much metal detectors and like all metal detectors operate on some variation of the principle of measuring a reflected induced magnetic field. I think wireless units may be even more succeptable.
I actually run a wired unit on my MTB because my K2 SmartShocks (front and rear) cause computer anomolies with wireless sensors. They have little piezoelectric valves in them that control fluid flow for damping control and I guess they emit enough EM to screw up the wireless transmission.
