The Frame and Construction 

Sunny Health & Fitness SF-RB4954 Evo-Fit Cardio Recumbent Bike

The construction of the Sunny Health & Fitness SF-RB4954 Evo-Fit Recumbent Bike features an anti-corrosion painted heavy-duty steel frame. While the seat post, the drive system, and the console cosmetic and safety covers are made of ABS material.  

Thus, it has an appealing outlook and sturdiness that supports a maximum user weight capacity of 300 lbs./136 kg.  

The robust base framework features adjustable levelers at the rear and the middle of it for maximum stability, traction, and floor-friendliness. Therefore, you can aggressively workout without feeling wobbling or tilting movement no matter how crooked the floor is.   

Moreover, its assembled weight of 100 lbs./45.3 kg further optimizes its overall stability. 

There are transport wheels and a lifting handle that are integrated for the easy relocation process of the bike.  

The Evo-Fit Cardio Recumbent Bike assembled dimensions are 62.6’’ long by 25’’ wide by 49.2’’ high. Simply put, it’s going to need a workout area with the perimeters of 5’3’’ length by 2’1’’ width and an additional clearance of 1-2′ around it for safety and easy access.  

Finally, the bike has an easy step-thru design that allows everyone regardless of their fitness status to effortlessly mount and dismount without struggle.

The Seat of the Sunny Health & Fitness SF-RB4954 Evo-Fit Recumbent Bike 

The seat, heart rate sensors, water bottle holder, seat adjustabment, and easy step-thru design of the Sunny Health & Fitness SF-RB4954 Evo-Fit Cardio Recumbent Bike

The 2-way adjustable seat with a backrest is large, contoured, and cushioned for a comfortable workout experience. It could be adjusted horizontally (forward & backward).  

Although, its height also increases or decreases when it is adjusted backward or forward respectively because the seat is attached to a slanted steel rail.  

Thus, users with inseams of 26’’min-34’’maximum can be accommodated.  

It is important to point out that the backrest doesn’t adjust independently without the seat. This means you cannot adjust it to recline because it is fixed.  

The seat’s dimensions are 15.5’’ long by 11’’ wide by 2’’ thick. It can easily be adjusted even while seated via the lever at the right side of it. Simply pull the adjustment lever to adjust to a suitable position and release it back.  

The Handlebars 

The Sunny Health & Fitness SF-RB4954 Evo-Fit Recumbent Bike has 2 sets of handlebars that are designated at the front mast and the seat. These allow users to work out in different postures they want.  

The handlebars attached to the seat provide leverage for aggressive and comfortable pedaling. They integrate EKG HR sensors for the transmission of the user’s heart rate data to the monitor when held during a workout.  

The 2 sets of handlebars are coated with a soft rubber foam that promotes secure and comfortable grips. They are optimally positioned to fit every user even though they are nonadjustable.  

The Pedals 

The self-leveling pedals on this bike are large with adjustable safety straps. They are also anti-slip designed to provide and maximize footing stability. 

Standard gym shoes and different foot sizes can be accommodated.  

The Drive  

The Sunny Health & Fitness SF-RB4954 Evo-Fit Recumbent Bike is equipped with a belt drive system. This means its operation is smooth, quiet, and requires no lubrication or adjustment as opposed to a chain drive system.  

In other words, it is maintenance-free and you can exercise with the bike at any time of the day without constituting a nuisance to the people around you.  

The drive consists of a durable anti-stretch poly V-belt, solid crankset, crank-arms, pulleys, and high inertia 8 lbs./3.6 kg flywheel.  

Since the drive is bidirectional, reverse pedaling is possible.  

The Resistance System 

This bike has a frictionless electromagnetic resistance system with 24 adjustable levels. The adjustment of the resistance is via the console and thus, the bike needs to be plugged into a power source for it to work.  

For this reason, a 9VOLTS, 2.5A, AC adapter is included in the package.   

The resistance system mainly comprises a magnetic brake pad, a servo motor, and the flywheel.  

To generate resistance, the motor moves the magnetic brake pad close to the flywheel and releases magnetic fields around it. So, none of the internal mechanisms come in direct contact during this process, and therefore, no part wears out and none will need to be replaced.  

Also, the bike’s operation remains smooth and quiet even when the resistance is deployed.  

The 24 resistance levels provide light to decent challenging workouts that could help users to realize their fitness goals.  

The Console 

The console, the dual device holder, cooling fan, USB charging port, and Bluetooth connectivity of the Sunny Health & Fitness SF-RB4954 Evo-Fit Recumbent Bike

As aforementioned, the Evo-Fit SF-RB4954 Recumbent bike has an advanced console with a couple of interesting features that include a backlit LCD monitor, 12 pre-installed workout programs, a Recovery Function, goal settings for Time, Calories, Distance, and Heart rate, and more.  

Each of the 12 preset workout programs has 16 segments with the same amount of time; and if selected, a resistance level is automatically engaged, while the Heart Rate Recovery Function displays a fitness rating that is usually between F1 (excellent) to F6 (poor).  

It has a Personal Mode that offers the opportunity for you to create a customized workout program that will be used immediately. While the HRC (Heart Rate Control) Mode adjusts your resistance level based on your heart rate and it has 4 programs that can be selected from and these include 55%, 75%, 90%, and Target Heart Beat (Custom).   

The monitor tracks workout stats such as Time, Distance, Watts, BMI, Speed, Calories, Temperature, Personal Mode, and Pulse with high readability that cannot be diminished by a poorly-lit environment.  

That said, the console is not telemetry-enabled, meaning it’s not compatible with any wireless HR device and doesn’t connect to any online app either.  

However, there are a couple of extras the console integrates.  


Bluetooth speakers, a USB charging port, a cooling fan, 2 tablet holders are incorporated into the console.  

You can sync a smartphone/tablet device with the speakers for a quality movie or musical audio output, keep the device charged up at all times while enjoying a cool breeze during a workout.    

Finally, there is a water bottle holder at the top of the drive system casing for keeping proper hydration during workouts, very important.  


The unit has all the features that make the relocation process easy, but it does require a little bit of space for storage.  

It has front-mounted transport wheels and a lifting handle at the rear. It weighs about 100 lbs./45.3 kg and requires a storage area with the perimeters of 5’3’’ length by 2’1’’ width.  

The ideal place for storage includes the garage, next to a wall, or better still, leave on a dedicated workout area.
