SB120 Frame Construction
Although it’s not a commercial-grade bike, the XTERRA Fitness SB120 does have a reasonably durable steel frame; the seat frame section supports a maximum user weight capacity of up to 250 lbs (113 kg).
The structure combines cylindrical and rectangular tubes in its construction for improved aesthetics. In addition, all the steel parts come coated with a light gray corrosion-resistant paint finish.
Of course, the bike also has several ABS parts. The most notable ones are the covers of the drive system. These black and blue sections match the upholstery on the seat and backrest. So, gray, black, and blue is the only color combination available for this bike.
The fully assembled bike is not extremely large. It is only 48.4″ (123 cm) long and 24.8″W (63 cm) wide. However, leaving at least two feet of clearance around it is still advisable for easy access is still advisable.
Speaking of ease of access, the XTERRA SB120 has a step-through frame type. The bike’s front unit with the drive and resistance systems is a few inches from the seat section to offer easy entry and exit. Therefore, it can be quite a plus for users with specific disabilities as it can help position the seat.
The bike isn’t too heavy, either. It is only 53 lbs (24 kg) with all the parts assembled. Thus, one person can carry and build the bike. Once completed, its relocation is accessible via the small wheels integrated into its front base. Also, its rear base features two polygonal ABS caps that can rotate, acting as levelers.
Seat and handlebars
The XTERRA Fitness SB120 features a seat designed for optimal comfort. The seat and backrest pad integrate approximately—1.5″ (4 cm) foam cushioning and durable vinyl covers.
The seat comes equipped with a lever-based adjustment system. Therefore, you can easily adjust its position while seated; you don’t have to get up and use adjustment knobs, as is the case for some other recumbent bikes. The backrest is directly attached to the seat’s metallic frame via four screws, which means it does not adjust independently from the seat.
The seat rail offers a reasonably long adjustment span. Its comfortability accommodates users between 5’1″ and 6’2″ (155 – 188 cm). As I’ve mentioned, the seat supports users up to 250 lbs (113 kg).
The bike comes equipped with two sets of handlebars. One is attached to the seat frame, the other to the front mast of the bike. The seat handlebars have extended grips, slightly curved at the front, for improved comfort. The distance between them is approximately 22″ (56 cm). In addition, they also integrate HR pulse sensors, and the bike’s fitness monitor can monitor your pulse.
The front handlebar consists of a short, slightly angled bar in the middle. They don’t have any sensors, just rubberized covers like the seat handlebars. None of the handlebars are adjustable.
SB120 Drive and resistance
The XTERRA SB120 recumbent bike integrates a belt drive system. This type of drive has several advantages. For example, a belt transmission doesn’t need periodic lubrication; therefore, you don’t have to worry about taking the bike’s front apart to lube the belt. Also, a belt drive delivers less vibration than a chain and promotes a tranquil pedaling motion.
Like most other recumbent bikes, the XTERRA SB120 has an internal flywheel. But since it’s a light-capacity bike, its flywheel is not too heavy. It weighs 8 lbs (4.4 kg), so the first resistance level is light and great for recovery training. It is also bi-directional. Thus, you can pedal in reverse if you want to alternate muscle focus.
The bike comes equipped with a manual magnetic resistance system. Thus, you won’t need an adapter or an external power source. Also, since the resistance system is manual, the bike cannot automatically change the tension levels, and there are no programs on the console.
The resistance system consists of an internal magnetic brake attached to the tension knob through a steel cable. Therefore, by turning the knob clockwise, the magnetic brake moves closer to the flywheel, increasing the pedaling difficulty.
The bike offers eight levels of resistance. The lowest one is very light and great for rehab training. Conversely, the 8th level of resistance provides a bit of extra tension, simulating a hill climb. However, the maximum resistance isn’t extreme due to the light flywheel.
Finally, the bike has a durable crankset featuring steel arms and weighted pedals. Each pedal has a non-slip surface and an adjustable strap.
Since the XTERRA Fitness SB120 is a basic bike, its fitness monitor does not offer many features. Instead, it’s a simple monitor that tracks time, speed, distance, calories, and pulse. In addition, it also has an odometer function, and its LCD has significant digits but without a backlight.
The speed and distance are in MPH and miles; there is no option to change them to metric units. The pulse reading function also requires you to hold on to the integrated pulse sensors. Unfortunately, the monitor is incompatible with wireless HR chest straps or armband pulse transmitters.
The fitness monitor is straightforward to use. It only has one button that covers all of its functions. By pressing the button repeatedly, you can scroll through the workout metrics and select the one you want to view.
There is also a Scan Mode, which you can choose the same way; when in the Scan Mode, the fitness monitor rotates the workout metrics showing each one for a few seconds.
A reset function is also available; you can reset all the numbers on the monitor by pressing and holding the button for a few seconds.
The bike’s fitness monitor is battery-powered, requiring two AA batteries, which come included with the bike. It starts up when you press the button or when you begin pedaling. It also automatically turns off to save battery life after a few minutes of inactivity on the bike.
The device holder is the last feature I can note regarding the fitness monitor. A small shelf is attached to its bottom for holding your tablet or phone while exercising. Unfortunately, the monitor does not have any ports (USB or AUX) to connect your phone or tablet.
SB120 Assembly and Maintenance
The bike’s drive and resistance unit comes pre-assembled and attached to the base frame. However, you still have to assemble the seat and add the two base bars, the front mast, the handlebars, the fitness monitor, and the pedals.
Therefore, it may take up to an hour of your time. However, the task is far from complicated; the manual provides all the necessary instructions and schematics. Also, an essential toolkit comes with the bike.
Once assembled, you don’t have to worry too much about maintenance. The internal parts don’t need lubrication (at least not for a long time). So, all you have to do in terms of care is keep the bike clean, periodically check for loose bolts, and retighten if necessary.
