It manages power delivery from the battery to the motor and processes signals from the sensors.
Comm Module
The communication module connects the bike to the Cowboy app via Bluetooth.
It handles firmware updates, connectivity and diagnostic communication.

The motor is located in the rear hub and provides electric assistance while you pedal.
