An Electric Foil Assist kit, also known as an E-Foil kit, is a device that can be attached to a traditional foil surfboard. It consists of a battery-powered electric motor, a propeller, speed controller and remote. When activated, the motor propels the board forward, allowing the rider to glide smoothly above the water's surface. E-Foils are controlled by a handheld remote, which adjusts the speed and direction of the board. They provide a unique and exhilarating surfing experience, as they can reach high speeds and are capable of riding in various water conditions.
