Hall Effect Sensor
This is a close up of the hall effect sensor that was originally on my motor on my bike. It is roughly equivalent to the Honeywell SS41 hall sensor series, although which type of SS41 sensor it nearest is up for debate. They produce a sensor labeled SS41F, which might perhaps be most similar, but is hardest to find. In the end I used SS41 and it worked fine. From everything I understand, the difference between the different sensors is not important for ebikes.
