Spirit ab900 commercial air bike  description the commercial spirit ab900 air bike uses air driven resistance, so the harder you pedal and the faster the fan rotates the more resistance is generated. Because the resistance matches the users effort it is ideal for both low resistance rehabilitation and first times exercises to high performance, high watt interval training. You also have the advantage of working the upper and lower body simultaneously, increasing both cardiovascular output and calorie burn. However you can also work the upper body alone by placing your feet on the foot rests and then proceed to push and pull the arms. Not only will you get a challenging upper body workout but a muscle building one as well. The comfortable moulded seat has both up and down adjustments and fore and aft adjustment for the perfect fit. The lcd console has a simple control keypad and displays all the important information. The bike has a built in windscreen to prevent blowback for user comfort.   features console programmes specifications warranty features unlimited air resistance upper and lower body workout lcd console anti skid foot pedals cushioned saddle vertical and horizontal seat adjustments integrated windscreen extra heavy commercial grade steel frame user weight 25 stone 159kg size l x 122cm w x 66cm h x 127cm 48” x 26” x 50” console 4aa battery operated lcd console display workout summary quick start target time target distance target calories target heart rate distance calories heart rate speed watts rpm calories interval programmes none specification 27 68.5cm 9 blade fan wheel 1 8 chain commercial grade structural steel frame durable powder coated paint finish user weight 25 stone 159kg size l x 122cm w x 66cm h x 127cm 48” x 26” x 50” product weight 54kg warranty full commercial with 3 years parts and labour free delivery options two man delivery on this product  due to heavy weight we will call you to arrange a suitable date installation service installation service available  click for details confused by all the options? call the store free on 0800 4580 081
