I've ridden the OW to 0% battery: you have plenty of warning before it gets dangerous. The OW has a feature called "pushback" - when the battery is nearly-depleted or you are going too fast, it will aggressively adjust the angle of the board backwards, forcing you to slow down. In the event of a low battery, you'll end up traveling at extremely low speed until the back end of the board touches the ground, forcing you to stop.
