The NordicTrack GX 5.2 indoor cycle offers a multi-level, adjustable resistance system to ensure versatile workouts, while a 22kg (48.5lbs) flywheel guarantees a smooth ride. It is supplied with a backlit LCD computer that enables you to monitor important workout statistics such as time, speed, distance, calories, pulse and RPM. Enhanced comfort is ensured by an adjustable seat with padding and adjustable ergonomic handlebars. For more safety and control, the bike incorporates a Quick-Stop breaking system which brings the flywheel to a complete stop and cage pedals with toe straps.
