In a previous life, I designed Access Control systems where we used Ground Loop detectors for gates and various other uses. For testing purposes we would place a tool box on the sensor to trip it, but I’ve heard of people using magnets or even rotating the front wheel “just right” to get the best results with a bicycle. Watched this video and found out that the 1-2 o’clock position on the loop is optimal, and staying still helps too.
