A usefull machine for the most demanding athletes! A training on the Air Spiner is a full body workout that builds muscle and improves cardiovascular endurance. The resistance increases as you pedal faster, while also keeping you cool. Air Spiner, a great look and feel, is a fantastic bike for everyone, from beginners to professional athletes. The multi-grip handlebar allows all users to find a comfortable hand position. The smooth, natural, unrestricted airflow/magnetic resistance (12 levels) provided by the double heavy-duty 56 cm steel fan with cross-connected steel blades, allows for a huge range of resistance options. The ergonomically moulded PU seat guarantees extra comfort and durability while the non-slip adjustable footrests provide more stability. With the infinitely adjustable quick-release handles, you can easily adjust the saddle and the multi-grip handlebar to your ideal set-up. To move your bike, use the knurled handles at the back to easily pick up the spiner.
