Meet the ElliptiGO Arc: an outdoor elliptical bike that lets you push your body hard while exploring your city. Its stand up riding position reduces stress on your neck and back. According to the manufacturer, the Arc helps you burn up to 33% more calories than a bike.
This outdoor elliptical bike provides you with a low-impact workout and lets you climb steep hills up to 30% grade. It supports a sprinting speed of over 20 mph. Since the steering column is removable, you can transport the Arc more easily. The bad news? This bike is not cheap.
