The Sunny SF-B2640 Air Resistance Bike is a perfect entry-level fan exercise bike that won’t break the bank! The SF-B2640 has an excellent compact design that won’t take up much space and offers the ability to perform effective total-body low-impact workouts in the comfort of your own home.
The SF-B2640 Air Resistance Bike utilizes a smooth and quiet belt drive system. It features a large 17” diameter fan that’s more effective than bikes with smaller fans as the more significant the fan-wheel, the more air resistance created, allowing for a more effective workout.
Air resistance works on the premise that the harder/faster you pedal, the higher the resistance becomes. This type of resistance essentially allows for unlimited resistance levels and puts the rider in control of their workout. You can also increase or decrease your workout intensity with Sunny SF-B2640’s simple-to-use turn-dial tension knob.
The air resistance system of the Sunny SF-B2640 allows you to work at your own pace, making it suitable for users of all fitness levels. The moving handlebars add a new dimension to a traditional cycling workout, allowing you to work your upper body as well as your lower body. Also, the dual handgrip design gives you a choice of hand positions with the effect of different muscle group workouts.
