The XTERRA UB120 is one of the upright bikes released by XTERRA fitness in 2020. It’s a pretty basic stationary bike, similar to the Marcy NS-1201U, or the TechFit B400. As opposed to the TechFit model, it lacks the seat horizontal slider feature, but the saddle does offer more cushioning.

Frame construction
Although it’s a light-capacity exercise bike, the XTERRA Fitness UB120 features a steel frame with a 
weight limit of 250 lbs (113 kg), which is not bad for a model in its category. All the steel tubes in its construction are coated with a corrosion-resistant paint finish. The color used is metallic gray, this being the only color available for this bike. Also, the side covers of the drive and resistance elements are made of ABS material, combining the blue and black, the characteristic colors of XTERRA fitness equipment.
The bike has quite a compact design. Its footprint is only 34.8″L x 21.9″W (98 x 56 cm). However, it still is recommended to leave at least two feet of clearance all around it for ease of access. Its highest point is given by the top of the handlebars which reach approx. 48.8″ (124 cm) above floor level.
The bike is fairly light as well. It weighs only 38.6 lbs (17.5 kg) so it can be carried and unboxed by only one person. Its front base has transport wheels for easy relocation. Also, its rear base is equipped with adjustable stabilizers.
Seat and handlebars
The XTERRA Fitness UB120 includes a large saddle, designed to provide more comfort and contact surface than a race saddle. Its top is made of polyurethane material with an internal layer of foam cushioning. The foam is thicker in its rear section. Also, the surface of 
the saddle is contoured for improved breathability.
The seat post features a triangular plate attachment system. The saddle attaches to this plate via three screws. As we’ve mentioned above, it doesn’t have the horizontal slider for front to back adjustment like other upright bikes. But nonetheless, its upright post features 8 adjustment positions. This being said, the bike is made to accommodate comfortably, users between 4’10” and 5’10” (147 – 178 cm).
The XTERRA UB120 upright exercise bike features a multi-grip handlebar. It offers the possibility to adopt a standard grip, a climbing grip, and a parallel grip. Both its sidebars are coated with a thick layer of rubber foam material for extra comfort.
The bike’s handlebar is non-adjustable. Its post does not adjust vertically, and the handlebar itself does not have the angle-adjustability feature, like the Circuit Fitness AMZ-594U, for example. It attaches to the upright post via two screws.
The side grips of the handlebar are equipped with metallic pulse sensors. Not all basic upright bikes offer this feature, so it’s a plus. Evidently, the included performance monitor has a pulse reading function as well.
Drive and resistance
The XTERRA Fitness UB120 upright bike is equipped with an 8.8-lb internal flywheel. Evidently, it 
doesn’t offer similar inertia to the 40-lb flywheel of the average spin bike but does have a perimeter-weighted design for extra inertia. Plus, the magnetic tension system provides extra pedaling difficulty.
The bike’s flywheel is bi-directional. It allows reverse pedaling, but coasting on the bike is not possible. Also, when pedaling in reverse, you will benefit from the same resistance as when pedaling forward, and the monitor will continue to track distance traveled, calories burned, etc.
The XTERRA UB120 features a manual magnetic resistance system. This means you don’t have to connect the bike to a power source, and you won’t be needing an adapter or power cord for it. But on the other hand, it cannot adjust the resistance automatically.
The bike’s resistance system consists of a magnetic brake. This element is connected to the tension knob on the front upright post of the bike through a steel wire. By turning this knob clockwise, the brake moves closer to the flywheel and adds more pedaling difficulty.
There are 8 tension levels available on the bike’s resistance adjustment knob. The first level provides a very light pedaling difficulty. For this difficulty level, the brake barely adds any resistance, so you will basically be working out only with the weight of the flywheel. Conversely, the 8th tension level provides considerably more resistance, simulating a hill climb and offering the possibility to perform a more intense workout.
Needless to say, since it’s a light-capacity upright exercise bike, the XTERRA UB120 is not meant for spin workouts. Therefore, it is not recommended to stand up on the pedals. However, the crank arms are steel made and the pedals are pretty durable. They’re made of sturdy polymer (probably polypropylene) and integrate weight elements. Therefore, they are self-leveling; they always turn face-up if you remove your feet from them. They’re also equipped with adjustable straps.
Performance monitor
The XTERRA UB120 upright bike is equipped with the same type of performance monitor as 
the XTERRA SB120 recumbent bike that we’ve already covered here. It’s a basic fitness meter without workout programs but does integrate a tablet holder.
The monitor unit features an LCD display (without backlight) that tracks time, speed, distance, total distance, calories burned, and pulse. It’s pretty easy to use; it only has one (Mode) button. By pressing the button repeatedly, you can select the workout metric that you want to view on the display. However, you can also select the unit’s Scan Mode and it will rotate all the metrics showing each one for 6 seconds.
The unit’s pulse reading function only works with the integrated sensors. The monitor is not telemetric. In other words, it cannot read your pulse from a wireless heart rate chest strap.
The performance monitor unit is battery-powered. It requires two AAA batteries which are included. It starts up when you press the Mode button or when you begin pedaling. It also automatically turns off after 4 minutes of inactivity on the bike.
Assembly and Maintenance
The main unit of the bike with all the drive and resistance elements comes pre-assembled. You only have to attach the two base pieces, the front upright bar, the performance monitor, the handlebars, the seat post, the saddle, and the pedals. This shouldn’t take more than 30-40 minutes of your time. All the necessary instructions are provided by the included manual, and a basic toolkit is also included.
The bike’s maintenance doesn’t require much. All the internal components are pre-lubricated from the factory, and since the bike has a belt drive system, it doesn’t require any lubrication. Thus, all you have to do is wipe the dust from the frame and periodically check for loose parts and bolts.
