The VCU is a Vehicle Control Unit developed in-house. The brain of the bike. It controls the network of interactions and makes the best calculations for performance. It also acts as a data acquisition system and a 4G module for connectivity that sends data every second to Stark servers for the status of the bike. The VCU is on top of the battery and holds the wire harness. The VCU administers the battery, the motor, receives data from the throttle, handles communications with the phone in the docking station, the map switch controls, the water pump controls, the fan, the charger.
