450SL Frame Construction

The Fitness Reality X-Class 450SL features a heavy-duty steel frame. In addition, it combines ovalized, cylindrical, rectangular tubes and several ABS covers for extra protection and an aesthetic touch.

Its main chassis is a one-piece part with precision-welded joints, an aspect reflected in the bike’s overall sturdiness.

The bike has a maximum user weight capacity of 325 lbs (147 kg). It also weighs more than 90 lbs (41 kg), offering superior stability. The bike’s rear base comes equipped with two large, adjustable levelers that rest on rubberized pads.

The front base features transport wheels, while the rear base integrates a lifting handle. These facilitate the relocation of the bike. The frame section under the seat has an ABS tray that can hold various accessories, like your phone, earplugs, remote control, or water bottle.

All the steel tubes in the bike’s construction come with a corrosion-resistant gray paint finish. The only exception is the seat rail assembly, which is 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 advisable to leave at least two feet of clearance on each side of the bike and at least one foot at the front and rear for ease of access.

One important aspect I have to mention is the bike’s step-through design, which can be quite a plus for users with specific disabilities. Because you don’t have to step over the main body of the bike, as is the case with some other recumbent bikes, positioning the seat and 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 leads to superior comfort, helps with the even dispersion of your weight, and improves breathability. In addition, the seat cushion has a durable vinyl weave on top, which also enhances breathability.

The backrest features a mesh structure similar to various office chairs. It is contoured, elastic, and provides excellent lumbar support. In addition, the mesh structure offers maximum breathability so that you won’t overheat during exercising.

The whole seat assembly is adjustable. It is attached to a heavy-duty stainless steel rail and adjusts closer to or farther from the pedals. The seat rail features several adjustment positions, and comfortability accommodates users between 5’0″ and 6’3″ (153 – 190 cm).

It is important to note that the backrest is directly attached to the seat assembly; it is not adjustable independently from the seat, nor does it recline.

The Fitness Reality X-Class 450SL has no handlebars at the front attached to the console mast. But on the other hand, the ones attached to the seat assembly remind me of the armrest of an armchair.

The two side armrests feature cushioned pads with the same vinyl weave on top of the seat. The front grips are slightly inclined forward and feature ball grips at the top. In addition, they also integrate HR pulse sensors.

450SL resistance and drive

The X-Class 450SL exercise bike comes equipped with a motorized magnetic resistance system. Therefore, it requires an external power source. Also, the monitor can auto-adjust the resistance depending on the user program.

The bike’s resistance system consists of an internal servo motor and a magnetic brake. As you select a tension level from the fitness monitor, the motor adjusts the brake’s position 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 impossible. The pedals continue to spin for as long as the flywheel is spinning.

Like most other exercise bikes with a magnetic resistance system, the X-Class 450SL uses a belt transmission. Therefore, you don’t have to worry about its lubrication. Also, it generates considerably less vibration than a chain.

Lastly, the bike comes 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 are durable nylon material; they have a non-slip surface and adjustable straps.

Fitness monitor

The Fitness Reality X-Class 450SL recumbent bike includes a mid-range fitness monitor featuring a multi-window LCD with an LED backlight. It tracks distance, total distance, time, speed, RPM, watts, and pulse.

The pulse reading function can track your heart rate through the sensors integrated into the handgrips, but it is also telemetric. Therefore, you can track your pulse through a wireless chest strap. However, this accessory does not come included with the bike.

The monitor has integrated Bluetooth technology. For instance, you can sync it with your tablet or smartphone, track your progress online, or plan each workout via the free MyCloudFitness app. This app is available for iOS and Android.

Nonetheless, if you don’t want to use the online feature, the monitor has its own 24 workout programs to keep you motivated. They include 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 button on the monitor. 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 monitor does not have a sound system or a cooling fan but does integrate a tablet holder.

450SL Assembly and Maintenance

Most of the bike’s frame comes pre-assembled, with the main drive and resistance elements already in place. However, you still have to attach the two base bars, seat elements, the monitor mast, the fitness monitor, the accessory trays, and the pedals.

Consequently, this may take more than an hour. However, the included manual provides clear assembly instructions, and an essential toolkit also comes with the bike.

Once assembled, you don’t have to worry too much about maintenance. Therefore, you must keep the unit clean, keep liquids away from the console, periodically check for loose bolts and retighten if necessary. In addition, the internal mechanism doesn’t need lubrication.

  2. Robert, this is a well-written comprehensive review of the Fitness Reality X-Class 450SL. At first glance, it looks a little intimidating, but you were very thorough in explaining the parts, components, and assembly. I like the technology around the resistance system. I think we are going to see more of these magnetic resistance systems in other equipment as well. My most significant issues were the size and weight, but I can see it will readily move into our storage room with little effort. As for not having handlebars, I don’t find it a con. I get the idea behind the design and the benefits of the arm support over the handlebars. Great article Robert, looking forward to reading more.

    I checked availability on Amazon, but unfortunately, it is not currently available, so I hope it will be back in stock.

  4. From what I can see, it has 24 workout programs, and the fact that it’s a recumbent bike is a massive plus for me, as I’m looking for something comfortable to use for extended periods. And the fact that it has a large and easy-to-read display is a big tick in the correct box for me.

    I’m no expert in this area, but from what I can gather, this bike looks well-built and has a solid frame. And the price point seems pretty reasonable for the features that it offers.

    The Fitness Reality X-Class 450SL Recumbent Bike is an excellent option for a comfortable and well-equipped exercise machine.
