The data points are gathered by the AutoBalancing processor via multiple sensors placed around the scooter. Their proprietary algorithm uses the data and leverages gyroscopic principles to ensure the vehicle remains upright. Furthermore, the self-balancing remains enabled for up to 5-7 kmph, increasing riding comfort. The system goes on standby mode after crossing 7 kmph speed.
