The ProGear 225 Foldable Magnetic Upright Bike has a heart pulse monitor. Transportation wheels allow you to move the bike to different room locations or if possible even in your closet. The heart rate monitor is included to ensure you are maximizing your calorie and fat burn, so we also included an easy-to-read computer LCD display that indicates calories burned, distance, time, speed, pulse, and scan. The battery life is up to 3 years, making it ideal for those who want to get fit and healthy. Ergonomically contoured seat cushion easily adjustable to fit 51 to 6 user heights. 3 Piece cranking system with magnetic tension provides a smooth and consistent pedaling motion.
