Body-Solid B4R Endurance Recumbent Bike

Body-Solid B4R Endurance Recumbent Bike

The Body-Solid B4R Endurance Recumbent Bike is a light-commercial-grade exercise machine with preset workout programs and an LED monitor.  

Its design enables users to easily walk in and out of it without hassles regardless of whether they are physically impaired or not.  

However, we think it should have had more features such as Bluetooth and workout app connectivity, a cooling fan, and a sound system as the Spirit Fitness XBR55 Recumbent Bike does.

Frame & Construction

The Body-Solid B4R Endurance Recumbent Bike has a commercial-grade steel frame. The frame is coated with black anti-corrosion paint, while the console casing, the drive system covers, and the seat’s backrest frame are made of durable and quality plastic.  

The recumbent bike supports 300 lbs./136 kg maximum user weight capacity.  

The stability is good because of the rectangular steel stabilizers with adjustable levelers integrated at the bases. Moreover, its assembled weight of 119 lbs./54 kg also enhances the overall stability.  

Transport wheels are attached to the front base for an easy relocation process even though it weighs more than 50 kg.  

The assembled dimensions are 64’’ long by 26’’ wide by 49’’ high. In other words, it is going to require a workout area with measurements of 5’33’’ (162.56 cm) in length by 2’16’’ (66 cm) in width. Also, it is recommended to leave at least 2’ clearance around the bike for a safe and convenient workout execution.  

The Seat of the Body-Solid B4R Endurance Recumbent Bike 

The seat of the Body-Solid B4R Endurance Recumbent Bike provides lumbar support

The heart-shaped seat is contoured and cushioned for maximum comfort, and its backrest is ventilated, and curvy for lumbar support just like the one on the Sunny Health & Fitness SF-RB420046.  

Thus, users will be able to train longer while experiencing consistent comfort. Although, there might be the need for an additional cushion on the seat. If that is the case, you may always use a gel seat cover that is readily available online.  

The seat is attached to a slanted chrome-plated rail that is supported by two steel bars for stability. It is horizontally adjustable so that users of different foot sizes can be accommodated.  

Although the supported inseam heights are not specified. However, users that are up to 6’5’’ tall can fit in.  

Adjustment of the seat can easily be done while seated through the lever-based adjustment system on the right side of it.  

Finally, the backrest is not independently adjustable. This means it cannot be adjusted to recline. It goes with the seat adjustment instead.  

The Handlebars 

The Body-Solid B4R Endurance Recumbent Bike has 2 sets of handlebars. One set is attached to the front mast, and the other set is attached to the seat.  

The one at the front mast is upwardly curved but does not have any control buttons or heart rate sensors integrated into it. It is not adjustable either. However, it is optimally positioned to be suitable for all users regardless of their size or height.  

While the handlebar on the seat is also not adjustable independently but has heart rate sensors integrated into it so that when grasped during a workout the user’s heart rate data could be read and transmitted to the monitor for observation.  

The 2 sets of handlebars are coated with anti-slip soft rubber foam material for firm and comfortable grips.  

The Pedals 

The pedals are textured, self-leveling, and made of quality plastic with a metallic core. They also have adjustable safety straps that keep the feet secure and comfortable during aggressive pedaling.  

They are attached to a solid crankset and chrome-plated crank arms.  

The Drive 

The B4R Endurance Recumbent Bike is a belt-driven machine that comprises an anti-stretch poly v belt and a heavy flywheel whose weight is not specified. Although, we believe that the weight of the flywheel could be up to 20 lbs./9 kg considering the overall weight of the bike is 119 lbs./54 kg.  

Therefore, the bike’s operation is vibration-free because of the consistent momentum provided by the flywheel. Moreover, its operation is also smooth and quiet as opposed to a chain-driven bike.  

Users will be able to exercise with the bike around family members or people living in close proximity without disturbing anyone.  

One other advantage of a belt drive system is that it does not require maintenance such as pre or post-lubrication or adjustment of any sort.  

It is possible to pedal in reverse in case you wish to diversify and tone more muscle groups because the pedals are bi-directional. Nevertheless, coasting is not possible though.  

The Resistance 

The Body-Solid B4R Endurance Recumbent Bike is equipped with a motorized magnetic resistance system that utilizes magnets, a servo motor, and the flywheel to generate resistance without friction.  

This means that the resistance is generated without the internal elements rubbing off on each other, instead magnetic fields are released around the flywheel to cause a drag that ultimately produces resistance.  

This also means that the bike’s operation will remain smooth and quiet and won’t require any replacement of parts in the long run.  

For the resistance to work, the bike needs to be plugged into a 120V power outlet, thus, a power adapter is included in the package.  

There are 2 ways to adjust the resistance; one way is via the increase and decrease buttons on the console, and the second way is automatic when a certain preset workout program is selected.  

The resistance system has 24 adjustable levels that are suitable for everyone that wishes to lose weight and improve cardiovascular health, and overall physical well-being.  

The Console 

The console of the Body-Solid B4R Endurance Recumbent Bike

The smart recumbent bike console has some interesting features that include the LED monitor, preset workout programs, user profiles, and more.  

First of all, the easy-to-read LED display tracks Time, Distance, Speed, Watts, RPM, calories, and Heart Rate. All the workout stats are displayed simultaneously on the segmented monitor screen.  

Speed and Distance measurement units can be toggled between mph/miles and km/h/km.  

The heart rate can be monitored when the handlebars with heart rate sensors are grasped during a workout or when a wireless HR chest strap (not included, to be purchased separately) is worn.  

There are 12 built-in programs that include Manual, Strength, Cardio, Hill, Fat Burn, Interval, Speed Training, Watts, Personal, Fitness, Target Heart Rate, and Random.  

Once a preset workout program is selected, a resistance level will automatically be assigned to your workout.  

There are 3 preset Heart Rate Controls that include 55%, 75%, and 90%, and a custom Heart Rate.  

The Random program, when selected, will randomly create a workout program for you.  

The Personal program consists of 5 user profiles that enable different users to enter their personal information such as age, weight, height, and sex for accurate workout data output.  

It is easy to navigate through the console via the Manual, Programs, HRC, Watts, Random, Personal, Increase/Decrease, Quick Start, Start/Stop, Enter, and Reset buttons.  

That said, the console is not compatible with any fitness workout app.  


The unit integrates device and water bottler holders for entertainment and maintenance of proper hydration purposes.  


This recumbent bike can be stored in an area with measurements of 5’33’’ (162.56 cm) in length by 2’16’’ (66 cm) in width, and it can easily be rolled away via the front-mounted transport wheels even though it weighs 119 lbs./54 kg.
