Sunny SF-B2729 Tornado LX Air Bike | Train Like a Champion

Train like a champion with infinite resistance on the Sunny SF-B2729 Tornado LX Air Bike by Sunny Health and Fitness. The newest Tornado LX Air Bike is more significant, sturdier, and more durable for the most challenging workout. 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, and 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. Get the right fit with the 4-way adjustable seat to ensure optimal posture and body mechanics.

The SF-B2729’s fitness monitor is Bluetooth compatible to receive accurate real-time heart rate readings (the HR chest strap does not come with the bike). The large multi-function screen displays your fitness metrics simultaneously as you pedal hard on the bike. In addition, the quick Access button makes programming your target goals easy.

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 vertical post, which are chrome coated.

The Sunny SF-B2729 isn’t a large fitness machine. However, 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, this is a plus for a fitness bike, as it results in excellent stability. So, differently put, you can be sure that it won’t rock during your exercise 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 one place to another, you will have to lift and handle only half its total weight.

One last aspect to note here is the front footpegs characteristic of 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 vertical 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, 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 resistance-generating element is the massive 25″ (63 cm) fan placed at the bike’s front.

The resistance created by it increases with your pedaling and handlebar movement speed. Therefore, the faster you pedal, the higher the fan’s resistance.

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 must pedal or move the handlebars faster.

The console features three distinctive interval workouts to achieve your desired fitness levels. 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.

Fitness Monitor

The fitness monitor supplied with the Sunny SF-B2729  fan bike offers quite more than the average simple one. First, it has a multi-panel LCD, which indicates time, total time, distance, calories, pulse, watts, speed, and RPMs. Unfortunately, the bike has no 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 monitor 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 them as needed.

4 thoughts on “Sunny SF-B2729 Tornado LX Air Bike | Train Like a Champion”

  1. I like that this fan bike has wheels to make it easier to move. At 330 pounds, I would hate to have to lift this bike every time you need to reposition it. If you don’t have to go up/down any stairs, this bike would be a great way to stay in shape when the weather is cold outside. And if you have a single-level house, you’ll still be able to move this bike around if you need to change the purpose of any of your rooms! 

    • Thanks for taking the time to read and comment on the Sunny SF-B2729 Fan Bike. Sorry for the confusion about the weight. The bike has a maximum user capacity of up to 330 lbs. The bike itself weighs 94 lbs when assembled.

      All the best!

  2. Wow, this would give you a substantial overall cardio workout, and it sounds excellent and compact to fit anywhere. I like that it has Bluetooth and can monitor your heart rate through the straps and that it gives you all the details on the performance monitor in front of you. I’m delighted with the great seat that is adjustable in so many ways. This is one problem that I’ve always had with bikes, and this looks like the ultimate comfort.

    An excellent review of a fantastic product, thanks.

    • Hi Lily, thanks for stopping by. I am glad that you like this Sunny SF-B2729 Tornado LX Air Bike. Do you currently have any pieces of exercise equipment at home?  If not, you should consider investing in some. During the time of COVID, many people are starting to invest in home exercise equipment. It’s convenient, and in the long run, it saves money over gym memberships.

      I’d be happy to provide some suggestions for you based on your requirements. Would you please let me know?

      Kind regards, Robert
