Our heated handlebar mittens come with three adjustable heat settings for your convenience. A simple press of the button changes the settings - green indicates low heat, blue for medium, and red signifies high heat, making it easy for you to adjust the temperature according to your comfort. Features: Handlebar mittens serve as an essential cold-weather accessory, ensuring your hands stay warm and comfortable amidst cold, rain, snow, and wind. Simply secure them tightly to your bike handlebars using the fastener tape, ensuring they stay in place without loosening. Our winter mittens designed with reflective design in multiple areas to protect you when riding in the dark. The high-elastic extended wrist guard fits snugly around the wrist, providing enhanced warmth by preventing cold wind from entering. This product is powered by a power bank (power bank is not included), making it compact and lightweight, perfect for carrying along with your bicycle.
