You can attach a small permanent magnet somewhere on your bike's frame and it will trigger the ground loops. They're a common add-on for motorcycles, too.

  that doesn’t work for the majority of these sensors as they rely on inductance

    In that case, simply install a chunk of steel under the bicycle - 150kg or so should be sufficient.

      I found steel rims to almost always work as long as you put it right over the middle line. In CA they often paint a little bike where you need to put it.

      A simulated inductance circuit would do

    Is there a way to visually tell what kind of sensor loop you're dealing with? I can verify that a magnet makes the difference for my steel-framed e-bike, but really there's only half a dozen lights in town (Gilroy, CA) that I frequently use.

      As far as I know all of the sensors that are embedded in the pavement use inductance.
