Generic Wheel Speed Sensor (2-Wire)
Simple wheel speed sensor for e-bike controllers. A spoke-mounted magnet passes a fork/chainstay-mounted Hall-effect sensor to generate speed pulses. 2-wire output (signal + ground). Used by some KT controllers for accurate speed display and speed-limit enforcement. One magnet = one pulse per wheel revolution. Most controllers derive speed from motor hall sensors and don't need this, but it improves accuracy on geared hub motors where motor RPM doesn't directly correspond to wheel speed.
In brief: Cadence pedal assist sensor. 1 pulses per revolution. From $3.
