Which Bosch sensor do you have?

Bosch has made three speed sensors. This slim sensor is for eBike System 2. It is not the Smart System Speed Sensor Slim (BCH3319) and not the earlier standard speed sensor that uses a spoke magnet. The slim sensor mounts at the frame dropout and needs a matching original Bosch magnet.
