Make sure that the riding route is smooth.Slide forward with the food standing on the floor before starting (like riding the scooter without power). Immediately press the acceleration button and lean forward to avoid falling over backward due to inertia, so that the electric scooter will enter the working status. Avoid pressing the handle with your body in the acceleration and deceleration process. Put one foot ahead and the other behind (like on the sliding plate/surfboard, put one foot ahead and the other behind by 70-90 for better comfort). Before riding the scooter, please put one foot on the scooter deck and the other foot on floor and push the scooter forward by kicking the floor for some distance, in this way, the scooter will get some impulse to run forward.
