Precor has been building equipment to withstand the repetitive, rigorous workouts of health clubs, hotels and spas for years, so they earn their reputation on quality and durability. The Precor RBK 815 Commercial Series Recumbent Exercise Bike is the exact same bike found in commercial fitness centers worldwide. The Precor RBK 815 Recumbent Bike features 6 programs and 25 resistance levels. The step-through design allows you to easily enter and exit the bike, seating you in a reclining position that takes weight off sensitive areas and distributes it over the patented air flex seat for a comfortable ride. A touch sensor built into the handlebars instantly displays your heart rate.
