Smooth operation and efficient motion gets you the most out of your cardio workout equipment. RESISTANCE EXERCISE BIKE: With a magnetic tension lever positioned conveniently on the upright arm by the handlebars, you can easily adjust the resistance level while still cycling. Choose between 8 resistance levels for a full indoor cycle workout. LCD SCREEN: Between the upright handlebars, this rear flywheel bike features a screen that tracks and displays calories burned, time, speed, and distance. It also features a media shelf where you can safely store your phone, keys, and other accessories.
