The Frame & Construction 

Sunny Health & Fitness SF-B2729 Air Bike

The Sunny Health & Fitness SF-B2729 Air Bike is an upright indoor cycling bike that is constructed on a heavy-duty steel frame coated with black anti-corrosion paint. It supports up to 149.6 kg (about 330 lbs.) maximum user weight capacity. There are also a few parts that are made of plastic such as the drivetrain covers, the stabilizers’ end caps, the console covers, and the transport wheels.   

Due to the base construction that includes strong triangular-shaped stabilizers and adjustable levelers, the bike guarantees a stable workout experience. This means no wobbling or rocking will be felt for the duration of your workout session.

It can easily be moved around the room even though it weighs 98.6 lbs./44.72 kg, via the transport wheels at the front base. There is also a lifting handle integrated into the rear stabilizer designed to help the user to lift it up during a relocation process.  

The bike is no different in size from regular spin bikes. The assembled dimensions are 55’’ long by 23.5’’ wide by 49” high. Differently put, it will require a workout area with measurements of 4’5’’ (139 cm) in length by 1’95’’ (59.69 cm) in width.  

However, additional clearance of 2’ would be required on each side and 3’ at the rear for safe and easy access purposes.  

The Seat of the Sunny Health & Fitness SF-B2729 Air Bike

The seat is 4-way adjustable; that is, it can be adjusted vertically and horizontally. This enables you to customize for a perfect fit.  

It is presumed that users between the heights of 4’10’’ to 6’4’’ tall can be accommodated comfortably. Nevertheless, the bike supports individuals with inseam heights of 28’’-41’’. Therefore, it will be wise to ascertain if your inseam height is supported.  

The seat dimensions are 11’’ long by 10.5’’ wide by 3’’ high.  Thus, it is a fairly large cushioned saddle that is covered with vinyl material for maximum comfort.  

However, it can be replaced since its connection mechanism is standard. Options are widely available online and in local bicycle shops. Better still, a gel seat cover or a cushion can be used to improve the level of comfort it provides.  

The Handlebars 

The handlebars are dual-action. They are full-motion arm exercisers that enable users to work out the upper body as they pedal. The core, the back, and the arm muscle groups are engaged and exercised during a workout.  

Moreover, there are foot pegs that are integrated for placing your feet whenever you wish to exercise only the upper body at a given time. In other words, you can exercise the upper body in isolation from the lower body if so wish.  

The handlebars are not multi-grip designed as those on the Octane Air Bike, and they aren’t adjustable either. They are padded with anti-slip rubber foam material for comfortable and secure grips.  

The handlebars are connected to the pedals in such a way that they are not independently operable. If the pedals move so are the handlebars as well and vice versa.  

Heart rate sensors are not integrated into the handlebars. However, the console is Bluetooth-enabled and can connect to a 5.3 kHz HR chest strap for pulse rate monitoring.  

The Pedals 

The pedals are standard bicycle types. They are made of durable ABS material and metallic alloy and have textured surfaces.  

The crank system is upgraded to support the stipulated maximum user weight capacity of 330 lbs./149.6 kg.  

Pedaling in reverse is possible but you can’t coast on the bike as one could on a road bicycle.  

Stand-up pedaling is not advised to be performed on this bike because it is not designed for it. 

Finally, the pedals can be replaced with another set of your choice. So, if you want bigger pedals, you might be able to do that.  

The Drive 

As opposed to the Schwinn Airdyne Exercise Bike that is equipped with a belt drive system, the Sunny Health & Fitness SF-B2729 Air Bike is chain driven.  

This means that its drive system comprises a chain and other elements such as a pulley, the 27.5’’ fan flywheel, and a belt that connects the wheel and the handlebars.   

The chain drive system does not provide smooth and quiet operation as a belt-driven bike does but it enables you to experience a real outdoor ride.  

The chain may require periodic lubrication to keep it functional without issues of a squeaking sound or outright breakage.  

Users will be able to exercise while they listen to music or watch a movie without any noise interference from the bike.  

The Resistance  

The Sunny Health & Fitness SF-B2729 Air Bike features an air resistance system that is progressive and dynamic.  

This type of resistance system becomes intense and challenging the harder or faster you pedal. In other words, the resistance intensity is dependent on the user’s pedaling tempo.  

Thus, everyone at any fitness level would appreciate the workout challenge they get because it is proportionate to their workout ability.  

There are no predefined resistance levels like it is on other standard upright bikes. The resistance changes in proportion to your pedaling speed.  

The Console 

The console of the Sunny Health & Fitness SF-B2729 Air Bike

As aforementioned, the console is Bluetooth-enabled. This means it is compatible with a 5.3 kHz HR chest strap. However, the heart rate device has to be purchased separately because it’s not included in the package.  

The console features an LCD monitor that tracks multiple workout stats simultaneously; these include Time, Speed, RPM, Distance, Calories, Watts, and Pulse.  

The readability is good if viewed in a room with good lighting, otherwise, it will be difficult to discern since the monitor is not backlit.  

Speed and Distance metric units are measured in mph/km/h and miles/km, respectively. You can toggle to the desired measuring unit you want.  

The first time the console is turned up, you will be prompted to enter your age info.  

There are 3 workout programs available and they include 10/20 Interval, 20/10 Interval, and Custom. It is also possible to set a countdown for Target Heart Rate, Target Calories, Target Distance, and Target Time.  

The Target Heart Rate only works when an HR chest strap device is used, and the display will switch between 65% and 85%, and if your heart rate is above or below the preset perimeter the monitor will continue to beep until the heart rate returns between 65% and 85%.  

The console is powered by 2 AA batteries (included).  


The Sunny Health & Fitness SF-B2729 Air Bike has a tablet holder built into the console. It can hold a smartphone or a large size tablet device for entertainment purposes.  

That said, any device placed on it would block the view of the monitor.

The unit is not foldable; however, it won’t be taking up too much storage space. An area with measurements of 4’5’’ (139 cm) in length by 1’95’’ (59.69 cm) in width will suffice for storage.  

There are transport wheels and a lifting handle on the bike that will assist in the relocation process. So, even though it weighs 98.6 lbs./44.72 kg, an individual can conveniently have it moved around the room without hassles.
