The Fitness Reality X-Class 9000 is a heavy-duty air resistance exercise bike but features a different frame structure than the Body-Solid Endurance FB300 or the Schwinn AD7 Airdyne. It basically has the frame of a spin bike, but instead of being equipped perimeter-weighted heavy flywheel, it has a fan as a moving element. It also doesn’t have any magnetic resistance system, so the fan is the only resistance generator.

Frame construction

The Fitness Reality X-Class 9000 features a heavy-duty frame made of steel tubing. It combines rectangular, hexagonal and ovalized bars for a professional aspect. The only non-steel parts are the covers of the belt and several other small covers.

The main frame is coated with a chip-resistant and rust-resistant paint finish. The color used is dark gray, with the “Fitness Reality” logo painted in red, black, and white. The seat post and the handlebar post feature a silver paint finish.

Compared to other spin bikes, the X-Class 9000 is slightly larger. It’s approx. 54.5″ long (138 cm) and 26″ (66 cm) wide. This being said, it’s recommended assign a usage area for it of at least 100″ x 70″ (254 x 177 cm).

The fully assembled unit is fairly heavy as well. It weighs approx. 99.5 lbs (45 kg). This means it provides excellent stability. Plus, its stability is enhanced by the 5 adjustable stabilizers with rubber pads.

The bike isn’t too difficult to move once it was assembled. Its front base is equipped with two transport wheels which facilitate its relocation.

Seat and handlebars

The Fitness Reality X-Class 9000 HIIT air resistance exercise bike features a superior seat in terms of ergonomics. To begin with, its saddle integrates a layer of foam cushioning which is thicker in its rear part. Its top has a longitudinal cutout to promote breathability during seated workouts. Its rear part has two shock absorption springs which improve its overall cushioning. Its cover is made of double-stitched, highly durable faux leather.

The attachment system of the saddle to its slider is standard. This being said, compatible options are widely available, so in case you want to replace it, you should be able to find a compatible saddle in any bike shop.

The bike’s seat is 4-way adjustable. Its upright post offers more than 10 adjustment positions, while its horizontal slider allows several inches of front-to-back travel for the seat. This being said, the bike should be able to accommodate users between 5’0″ and 6’4″ (153 – 194 cm) with no problem. Also, the bike is rated for a weight capacity of 300 lbs (136 kg), so its seat assembly shouldn’t have any problem supporting users up to this weight.

The bike’s handlebar also offers 4-way adjustability, just as the seat. It has a multi-grip design, with a central transversal bar and a small loop aero bar at the front, to which the console is attached. These being said, it offers the possibility of an aero grip, rage grip, standard grip, and more. It’s fully covered by a layer of high-density foam in order to provide a comfortable and secure grip.

Both the seat and the handlebar feature large knobs which are easy to grip and turn. Therefore, adjusting the bike to your size shouldn’t take more than a minute.

Resistance and drive

As we’ve mentioned above, the Fitness Reality X-Class 9000 is an air resistance bike. It does not have any friction resistance or magnetic resistance mechanism. The one and only resistance generator is its flywheel. This being said, the bike’s resistance is non-adjustable. However, it does provide a dynamic response. In other words, the faster you pedal, the more resistance you will get.

Although the bike features a heavy-duty construction, has the frame structure of a spin bike and can handle pedaling while standing up on the pedals, it is not made for spin workouts. Spinning pretty much requires a compact and heavy flywheel.

The bike’s fan is steel-made, 19.3″ (49 cm) in diameter. It provides plenty of resistance to make you sweat in a very short time from the commencing of your workout session if you pedal at a high speed. Evidently, it’s bi-directional; therefore, you can pedal in reverse if you want to diversify your workout sessions.

The bike uses a belt drive system, featuring a durable poly-v belt. This means the ride is extremely smooth and quiet while vibration is almost inexistent. Also, you don’t have to lubricate it, so there is no maintenance hassle when it comes to the unit’s drive system.

The unit’s crankset is also a heavy-duty part, featuring solid steel crank arms. As we’ve mentioned above, the bike can hold users up to 300 lbs (136 kg), and that stands for the pedals and crank arms too. The pedals are made of metallic alloy. They do not have clips for spin shoes but do have toe cages and straps in case you want to secure your feet during pedaling.


This Fitness Reality exercise bike includes a HIIT console. It features a multi-window display with LED backlight, which tracks time, distance, speed, RPM, calories, watts, and pulse. Time and distance are shown on the display at all times, while for the speed, calories, and RPM, there is a SCAN mode which rotates them showing each one for 4 seconds. You can also press the Mode button to select any of these three workout stats to be shown all the time.

The console unit offers both metric and imperial units for speed and distance. For pulse reading, it does not have any sensors integrated into the handlebars, but can read your pulse via the included Bluetooth HR chest strap.

There are three interval programs and three target settings available on the console. Each program has its own button for quick selection. The interval programs are 20/10, 30/90, and custom. Differently put, if you select the 20/10 Interval program, the console will prompt you to intensely workout for 20 seconds, then rest for 10 seconds (or considerably reduce your pace). For the other program, the work interval is 30 sec, and the rest interval is 90 sec. And finally, for the custom interval program, you can set up the duration of the rest and work intervals.

The target programs give you the possibility to select a goal for time, distance, and calories. Once a goal is selected for any of these workout statistics, the console will show the remaining amount from the selected goal and will notify you when you have completed it.

The bike is also compatible with the free MyCloudFitness app available for iOS and Android smart devices. Therefore, you can sync the console with your smartphone or tablet and track your progress via this app.

Last but not least, the console requires 4 AAA batteries to function; these are included. It starts up when you press the Mode button, and also has a sleep mode to which will enter after 4 minutes of inactivity on the bike.

Assembly and Maintenance

The main frame of the bike comes pre-assembled. In other words, the fan, the drive belt, and the crank assembly are already installed. You only have to add the two base stabilizer bars, the seat post, the seat, the handlebar post housing, the handlebar post, the handlebar, the console, and the pedals. This may take up to an hour; however, it’s far from being a complicated task. Plus, the manual provides very clear assembly instruction and a basic toolkit is also included.

For maintenance, it’s recommended to periodically check the bike for loose bolts and parts. The fan and its housing may accumulate dust, which can be easily vacuumed from the outside, without removing any parts. The drivetrain does not require any lubrication.

4 thoughts on “Fitness Reality X-Class 9000 Air Resistance HIIT Indoor Cycling Bike”

    1. Their construction and air resistance elements are different, but the pedaling feel and workout should be similar. The FR X-Class 9000 does seem to have a more comfortable seat, though.

  1. How does it compare to a traditional Spin bike? The frame looks like a spin bike, however, it appears that they tried to combine an air dyme with a spin bike frame. I have been spinning for about 10 years and only did an air bike once or twice so I am not as familiar with that type of workout.

    1. First of all, since the bike uses air resistance, the “feel” is different, and there’s the dynamic response (the faster you move, the more resistance you get). Second of all, it lacks the inertia generated by the heavy and perimeter-weighted flywheel of a spin bike. So, at least for the start of the workout, the consistency of the motion feels lower.
