The XTERRA Fitness SB120 Recumbent Bike

How Good Is XTERRA Fitness SB120 Recumbent Bike Good?

The XTERRA Fitness SB120 Recumbent Bike does not have fancy features as the NordicTrack R35 Recumbent Bike does. On the contrary, it has basic and similar features as those on the XTERRA UB120 Upright Bike. They support the same maximum user weight capacity, have the same flywheel with the same weight, and have the same type of console.  

The SB120 Recumbent Bike is the conventional exercise machine that only provides low-impact exercises for the lower body, and that’s it.

It is not like the Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike which also allows users to work on a laptop while exercising, and the Sunny Health & Fitness SF-RB4936 Cross Trainer Recumbent Bike which enables users to experience full-body cardiovascular workouts.

The Frame & Construction of the XTERRA Fitness SB120 Recumbent Bike 

This recumbent exercise bike has a sturdy steel frame that embodies other parts that are made of quality plastic. These plastic-made parts include the drive train covers, the stabilizer bar end caps, the console casing, the pedals, and the tension control knob. 

The bike is built to be durable and aesthetic. It supports 250 lbs./113 kg maximum user weight capacity. 

Its structural design also ensures enhanced stability. Thus, users can exercise on it without experiencing wobbling or anything of that nature. 

Users usually buy the unit alongside a protective rubber mat to help improve its stability on certain types of floors.  

It is compact when compared to other recumbent bikes such as the NordicTrack R35 Recumbent Bike. Its overall assembled dimensions are 48.4’’ long by 24.8’’ wide by 42.5’’ high. Hence, a workout area with measurements of 4’ (123 cm) in length by 2’ (63 cm) in width will be accommodative. Nevertheless, a clearance of at least 2’ must be left around the bike for safety mounting and exit.  

Finally, users can easily mount and dismount the bike due to its step-thru design, and it can be moved around the room via the front built-in transport wheels without much effort. 

The Seat  

The seat of the XTERRA Fitness SB120 Recumbent Bike

The seat of recumbent bikes is usually comfortable largely because of the backrest that supports the back, and so is the seat on the XTERRA Fitness SB120 Recumbent Bike.  

The seat is large and padded, and the backrest is long, wide, and padded as well, covering and giving enough support to the back so that users can train longer without feeling fatigued.  

It is 2-way adjustable; this means it can be adjusted forward and backward. And since the seat is attached to a slanted steel base, the height of the seat also slightly increases and decreases when it is adjusted backward or forward.  

Therefore, users between the heights of 4’10’’ to 5’10’’ can be accommodated.  

An adjustment lever is attached to the right side of the seat which enables you to move the seat backward or forward even while seated.  

By the way, chances are you won’t need to do anything to improve the seat’s comfortability. Nevertheless, if you ever want to do so, the use of a gel seat cover can do the trick.  

The Handlebar 

There are 2 sets of handlebars; one set is located at the seat, and the other at the front post right below the console. They are both padded with anti-slip rubber foam material for maximum secure and comfortable grips.  

These handlebars offer users the opportunity to work out in different positions.  

The seat handlebar integrates heart rate sensors on each handle so that when you grasp them during a workout your heart rate data will be read and displayed on the monitor.  

Finally, the handlebars are nonadjustable.  


The pedals have a standard design. They are wide and textured with safety adjustable straps so that different foot sizes can be accommodated securely and comfortably. 

They are made of solid plastic with a metallic core.  

Their crank arms are sturdy and chrome-plated. 

The Drive 

Recumbent bikes usually have a belt drive system, and so does the XTERRA Fitness SB120 Recumbent Bike.  

A belt drive system comprises an anti-stretch V-Poly belt, a pulley, and a flywheel. Hence, its operation is smooth and quiet.  

Users will be able to exercise without distraction and the people around them won’t be disturbed either.  

For this reason, the XTERRA Fitness SB120 Recumbent Bike is good for home or office use. You can watch TV shows or listen to your favorite music while exercising on the bike.  

Another advantage of the belt drive system is that it doesn’t need you to carry out any type of maintenance. In other words, it is maintenance-free. 

Pedaling in reverse is possible since the drive system is bidirectional.  

The Resistance 

The XTERRA Fitness SB120 Recumbent Bike is equipped with a manual magnetic resistance system. The resistance system consists of a magnetic brake pad and the 8.8 lbs./4 kg perimeter-weight flywheel. 

This type of resistance system has a clean process of generating resistance without friction. In other words, it generates resistance by the release of magnetic fields around the flywheel which will ultimately cause a drag that will result in resistance.  

The intensity of a given resistance level depends on how close or farther away the magnetic brake pad is to the flywheel. The 8 resistance levels of the resistance system provide easy to difficult workout challenges suitable for weight loss, and overall health improvement.  

A tension control knob which is used for adjusting the level of resistance is located on the top of the drive train covers. To increase or decrease the resistance turn the tension knob clockwise and counterclockwise, respectively.

Since there is no friction in the process of generating resistance, no part will be affected by wear and tear. Thus, no part replacement will be needed in the long run, and no sort of maintenance will also be required.  

Furthermore, the bike’s operation remains smooth and quiet regardless of whether the resistance is engaged or not.  

The Console of the XTERRA Fitness SB120 Recumbent Bike

The console of the XTERRA Fitness SB120 Recumbent Bike

The console featured on this recumbent bike is simple and basic. It has an LCD monitor that tracks workout stats such as Time, Distance, Speed, Calories, and Pulse. The heart rate data shows up on the display if the user grasps the seat handlebar with the heart rate sensors.  

Speed and Distance measurement units are in mph and miles.  

The monitor has a small display window; hence it can’t display all the metrics simultaneously. Instead, it has a SCAN function that continuously displays the workout stats one at a time.  

If you desire to only view a certain workout stat, you can override the SCAN function by setting the workout value you wish to observe.  

The monitor is battery-powered (2 AA batteries included). 

There is only a single button on the console for navigation purposes and it is easy to use. Everything you need to know about it is outlined in the bike’s instruction manual.  

The Accessory 

The XTERRA Fitness Recumbent Bike has a built-in tablet holder for smartphone/tablet device placement. Therefore, users can use a device to watch workout and entertainment videos. 


This recumbent is not bulky. It is compact, lightweight, and portable.  

A storage area with measurements of 4’ (123 cm) in length by 2’ (63 cm) in width can accommodate it. The built-in transport wheels at the front base allow users to easily move the unit around.
