A stationary bike is a piece of exercise equipment designed for indoor cycling. It features a seat, handlebars, and pedals, allowing users to simulate the experience of riding a bicycle without moving. Stationary bikes come in various styles, including upright and recumbent models, catering to different fitness levels and preferences. They are commonly used in gyms and homes for cardiovascular workouts. These bikes often include adjustable resistance settings, enabling users to increase or decrease the intensity of their workout. Many stationary bikes also come with built-in monitors that track metrics such as distance, speed, and calories burned, helping users to monitor their progress and stay motivated.
