It has the same frame construction but comes with an improved console with 24 workout programs, which is compatible with the myCloudFitness app. Although it’s not advertised as a commercial-grade bike, it definitely offers the comfort and sturdiness of at least a light-commercial model.

The Fitness Reality X-Class 450SL features a heavy-duty steel frame. It combines ovalized, cylindrical, and rectangular tubes, along with several ABS covers for extra protection and an aesthetic touch. As we’ve mentioned above, the bike has a construction similar to various other commercial bikes, such as the NordicTrack VR21, for example. Its main chassis is a one-piece part with precision-welded joints, an aspect which is reflected into the overall sturdiness of the bike as well.
The bike is rated for a weight capacity of 325 lbs (147 kg). It also weighs more than 90 lbs (41 kg), offering superior stability.
Speaking of stability, the rear base of the bike is equipped with two large, adjustable levelers which rest on rubberized pads. There is also an auxiliary stabilizer at the middle of the frame. Therefore, you can perfectly level the unit on any type of floor. The front base features a set of transport wheels while the rear base integrates a lifting handle. These facilitate the relocation of the bike. Also, the frame section under the seat is equipped with an ABS tray which can serve as support for various accessories, like your phone, earplugs, remote control, or water bottle.
All the steel tubes in the bike’s construction are coated with a corrosion-resistant finish. The color used is gray, this being the only color available for this bike version. The only exception is the seat rail assembly which is made of stainless steel.
The fully assembled bike is fairly large compared to other models. It is approx. 60.5″ (154 cm) long, and 34.5″ (88 cm) wide. It is also recommended to leave at least two feet of clearance on each side of the bike, and at least one foot of clearance at the front and rear for ease of access.
One last important aspect that we have to mention here regards the unit’s step-through design. This can be quite a plus for users with certain disabilities. Due to the fact that you don’t have to step over the main body of the bike, as it is the case for the BodyCraft R200 for example, the positioning on the seat and the positioning of your feet on the pedals can be done considerably easier.
Seat and handlebars
The Fitness Reality X-Class 450SL recumbent bike features the same seat as the X-Class 310SX. It is approx. 15″ (38 cm) wide, offering plenty of contact surface. The seat pad integrates a thick layer of high-density foam at the bottom and a layer of air-cell cushions on top. This structure not only that leads to superior comfort, it helps with the even dispersion of your weight, also improving breathability. The seat cushion has a durable vinyl weave on top which also improves breathability.
The backrest features a mesh structure similar to various office chairs. It is contoured, elastic and provides excellent lumbar support. The mesh structure offers maximum breathability, so you won’t overheat during exercising.
The whole seat assembly is adjustable. It is attached to a heavy-duty stainless steel rail and can be moved with ease closer or farther from the pedals. The seat rail features several adjustment positions, and can accommodate users between 5’0″ and 6’3″ (153 – 190 cm).
It is important to mention that the backrest is directly attached to the seat assembly; it cannot be adjusted independently from the rest of the seat. It does not recline, nor it can be set higher or lower.
The Fitness Reality X-Class 450SL doesn’t have any handlebars at the front, attached to the console mast. But on the other hand, the ones attached to the seat assembly remind of the armrest of an armchair. The two side armrests feature cushioned pads with the same vinyl weave on top as the seat. The front grips are slightly inclined forward and feature ball grips at the top. They also integrate pulse sensors.
Resistance and drive
The X-Class 450SL exercise bike is equipped with a motorized magnetic resistance system. This means it requires an external power source. Also, the console can auto-adjust the resistance depending on the program in use.
The bike’s resistance system consists of an internal servo motor and a magnetic brake. As you select a tension level from the console, the motor adjusts the position of the brake in relation to the flywheel, increasing or decreasing the resistance.
There are 24 levels of resistance available on this bike. The first few levels deliver a light pedaling difficulty, great for recovery training or low-intensity cardio training. Conversely, the resistance settings from 20-24 programs offer the possibility to train on a higher level, simulating a hill climb.
The weight of the internal flywheel is not specified. However, considering the bike’s overall weight, it probably weighs 20 lbs (9 kg) or more. It is a balanced flywheel, designed to provide a smooth pedaling motion. It also allows reverse pedaling; however, coasting on the bike is not possible. The pedals continue to spin for as long as the flywheel is spinning, especially is a lower level of resistance is selected.
Like most other exercise bikes with a magnetic resistance system, the X-Class 450SL uses a belt transmission. This being said, you don’t have to worry about its lubrication. Also, it generates considerably less vibration than a chain.
Last but not least, the bike is equipped with a durable crankset, featuring steel crank arms. The pedals have a weighted design; this means they always turn face-up when you remove your feet from them. They’re made of durable nylon material, they have a non-slip surface and adjustable straps.
The Fitness Reality X-Class 450SL exercise bike includes a mid-range console featuring a multi-window LCD display with LED backlight. It tracks distance, total distance, time, speed, RPM, watts, and pulse. With regards to the pulse reading function, it can track your heart rate through the sensors integrated into the handgrips, but it is also telemetric. This means it can track your pulse through a wireless chest strap, but this accessory is not included.
The console has integrated Bluetooth technology. This means you can sync it with your tablet or smartphone and track your progress online or plan each and every workout via the free myCloudFitness app. This app is available for iOS and Android.
Nonetheless, in case you don’t want to use the online feature, the console has its own 24 workout programs to keep you motivated. Each program has its own specific; the list includes programs for weight loss, interval training, hill climbing, or programs that require you to keep within a given heart rate interval. You can also select goals for time, distance, and calories burned.
A Recovery function is also available. This program has its own button on the console. It measures how long it takes your pulse to return to normal after the workout and based on the result, it will give you a fitness rating between F1 (excellent) and F6 (poor).
Finally, the console does not have a sound system or a cooling fan, but does integrate a tablet holder.
Assembly and Maintenance
Most of the bike’s frame comes pre-assembled, with the main drive and resistance elements already in their place. However, you still have to attach the two base bars, all the seat elements, the console mast, the console, the accessory trays, and the pedals. This may take more than an hour. However, the included manual provides very clear assembly instructions and a basic toolkit is also included.
Once the bike is assembled, you don’t have to worry too much about maintenance. All you have to do is keep the unit clean, keep liquids away from the console, and periodically check for loose bolts. The internal mechanism doesn’t need lubrication.
