In addition, the heavy-duty steel frame holds an incredible 330LBS, which maximizes stability during vigorous rides.
The higher your speed and force, the more resistance this air bike can make! The commercial-grade oversized 25-inch fan wheel drives unlimited air resistance as you pedal forward with solid momentum. In addition, the stylish red paddles are enclosed in an upgraded fan cover guard to protect accidental dirt and debris from damaging the fan.
The SF-B2729 has ergonomic extreme grip handlebars designed to increase muscle engagement in the arms, back, shoulders during the push and pull action. In addition, the sizeable non-slip foot pedals will keep your feet secure during slow or rapid pedal strokes.

SF-B2729 Frame construction
The Sunny SF-B2729 Tornado LX fan bike features a steel-made frame, offering a sturdy build and riding feel. The only PVC parts in its construction are the crank and chain guards, which do not reduce the bike’s overall sturdiness. In addition, the steel parts come with corrosion-resistant light grey paint, except for the seat slider and upright post, chrome coated.
The Sunny SF-B2729 isn’t a large fitness machine. It takes considerably less space than a treadmill or an elliptical trainer. When fully assembled, the bike is 56″ (142 cm) long and 23.5″ (60 cm) wide. The recommended workout area is approx. 80″ x 48″ (203 x 122 cm). Thus, it can be an excellent choice for a fitness machine if storage and usage space are issues.
When fully assembled, it weighs approximately 94 lbs (42.6 kg). However, for a fitness bike, this is a plus, as it results in excellent stability. So, differently put, you can be sure that it won’t rock during your exercising routines.
This exercise bike is not foldable. However, its front base comes with a set of wheels that facilitate its relocation. If you use the wheels to transport it from a place to another, you will have to lift and handle only half of its total weight.
One last aspect to note here regards the front footpegs characteristic to most exercise bikes with mobile handlebars. This bike has this feature and allows you to rest your feet on these pegs if you only want to exercise by using your arms.
Seat and handlebars
The Sunny SF-B2729 Tornado LX comes with a 4-way adjustable seat. You can also tilt back the seat slightly if you want.
Its horizontal slider allows for a 16″ – 39.6″ (40 – 100 cm) distance span between one handlebar and seat axis. Its upright post offers an adjustment span between 29.5″ and 42″ (75 – 106 cm), while the distance between the seat and the front foot resting pegs can vary between 30″ – 41″ (76 – 104 cm).
Thus, the bike can comfortably accommodate users between 5’0″ and 6’5″ (153 – 195 cm), and up to 330 lbs (150 kg). But as a general idea, shorter users may find the arms stretch during the handlebars a bit uncomfortable. This is remedied by adding grip extensions to the handlebars.
The included saddle offers optimal comfort for an upright bike. Admittedly, it’s not precisely the widest you can find, but still, it is considerably more extensive than the average spin bike seat.
It integrates a decent layer of padding and features a longitudinal groove to promote healthy circulation. In addition, its connection point to the slider is standard; therefore, compatible options are widely available if you ever need to replace them.
The bike’s handlebars are simple bars curved outward and finished with rubberized grips. Since it’s a fan bike, they’re mobile and synchronized with the movement of the pedals.
The handlebars do not lock into place. They will continue to move as you pedal. However, you can rest your feet on the front legs if you only want to exercise using the handlebars.
The handlebars are non-adjustable. However, the seat does feature large knobs that are very easy to grip, turn, and lock, to facilitate a quick adjustment.
SF-B2729 Drive and resistance
The Sunny Health & Fitness SF-B2729 Tornado LX fan bike comes with a chain drive. This comes with two main advantages. First, the chain is considerably more durable than a belt and can last a lifetime with proper care. Two, it’s a standard bike chain, and you can easily find a replacement for it if it’s the case. The main downside of it is that it requires lubrication from time to time.
The bike features a very solid crankset with steel crank arms. The pedals are simple, though, without foot straps or clips for SPD shoes. The crankset is substantial enough to support the user in standing-up pedaling sessions. However, since this is technically an upright bike and not a spin bike, spin workouts are not advisable.
As the title suggests, this Sunny Health & Fitness exercise bike features an air resistance system. The massive 25″ (63 cm) fan placed at the bike’s front is the resistance generating element.
The resistance created by it increases with your pedaling and handlebar movement speed. Therefore, the faster you pedal, the higher the resistance the fan will produce.
If you’re wondering, there isn’t any damper, such as the Concept2 Model D rower, for example, or any other resistance adjustment element. So, the overall resistance of the bike is not adjustable.
It depends solely on your pedaling speed. Therefore, if you want more resistance and more intense cardio training, you will have to pedal or move the handlebars faster.
The console features three distinctive interval workouts to undertake to achieve your desired levels of fitness. As a general idea, the resistance supplied by this exercise bike promotes light to medium workouts. As a result, it’s a great exercise bike for interval workouts.
The fitness monitor supplied with the Sunny SF-B2729 fan bike offers quite more than the average simple one. First of all, it has a multi-panel LCD, which indicates time, total time, distance, calories, pulse, watts, speed, and RPMs. Unfortunately, the bike does not have any EKG sensors, but the monitor is compatible with Bluetooth HR chest strap transmitters.
The fitness monitor is programmable. It features three main interval programs: 10/20 Interval, 20/10 Interval, and Custom Interval. It also has functions for setting a target for time, distance, calories, and heart rate.
So, when using it in manual mode, the values will go up as you exercise. However, selecting a specific target for distance will count down from the chosen target distance until it reaches 0. The same goes for time and calories.
As for heart rate, during your workout, the monitor will switch between 65% and 85% heart rate. If your heart rate goes below 65% or above 85%, the monitor will beep until your heart rate is between 65% and 85%.
The fitness monitor is straightforward to operate. It has buttons for the Target functions and each interval program. The lower part’s arrow keys allow you to increase/decrease a value, while the Enter key covers the selection function. The Star/Stop keys will enable you to pause and resume your workout without losing your progress.
The unit is battery-powered, and it uses 2 AA batteries, which come with the bike.
SF-B2729 Assembly and Maintenance
The flywheel fan, the drive elements, and the crankset are already attached to the mainframe. Therefore, the assembly requires you to connect the base tubes, the seat, the pedals, the monitor mast, and the handlebars. This shouldn’t take more than an hour. The manual provides pretty clear assembly instructions.
For maintenance, you will have to lubricate the bike’s chain periodically. Other than that, it’s advisable to check for loose bolts or parts from time to time and retighten as needed.
