A hoverboard is a self-balancing electric device that allows a person to glide smoothly over flat surfaces. It typically consists of two wheels and a platform for standing, with sensors that detect the rider's movements. By leaning forward or backward, users can control their speed and direction, making it a fun and exciting way to travel short distances. These devices gained popularity in the mid-2010s, often seen in parks and urban areas. While they are sometimes confused with segways, hoverboards are smaller and more portable. Safety gear, like helmets and knee pads, is recommended for beginners to prevent injuries while riding.
