If you want to get an inexpensive exercise bike, then the XTERRA SB150 Recumbent Bike is for you. The frame of the SB150 is strong and durable and comes with a maximum user weight capacity of up to 265 lbs (120 kg). It also features a walk-through design. As a result, it is easily accessible.
The SB150 has a decent flywheel that provides a smooth pedaling motion and delivers consistency. Moreover, the flywheel is also bidirectional. As a result, you can pedal backward and still have a proper intensity. The flywheel weighs 11 lbs (5 kg), so you can only expect the bike to offer a light resistance. However, it has up to 24 levels of resistance.
The XTERRA SB150 comes equipped with a 3.7” LCD with a blue LED backlight. It tracks all the essential workout metrics, including time, distance, calories burned, speed, RPM, and pulse. Additionally, it has 12 preset programs, four customizable workouts, five heart rate programs, and a manual.

SB150 Frame construction
The XTERRA SB150 features a reasonably sturdy frame rated for users up to 265 lbs (120 kg). It comes in two main pieces: the front part, which holds the drive and resistance elements, the console mast and the console, and the rear aspect with the seat assembly.
Most of the bike’s frame is steel tubing. The only exceptions are the covers of the drive and resistance parts and the seat base covers. These are durable ABS materials.
The frame features a step-through design. Thus it offers easy access to the seat. This can be quite a plus for users with specific disabilities.
All the steel bars in the bike’s frame are double-coated with a chip-resistant and corrosion-resistant paint finish. The color used is black, this being the only color available for this unit.
This XTERRA exercise bike is not an extremely large fitness machine, but it’s not too small either. With the frame fully assembled, its footprint is approx. 58.3″L x 24.8″W (148 x 63 cm). On top of that, it’s advisable to leave at least two feet of clearance all around it for safe operation.
The bike is not extremely heavy, either. When fully assembled, it weighs only 69.5 lbs (31.5 kg). However, the front base also comes equipped with a set of wheels to facilitate its transport.
The bike’s rear base comes with a set of adjustable levelers. There’s also an additional adjustable leveler in the middle of the mainframe bar. Therefore, the bike will correctly stabilize on any floor.
Seat and handlebars
The XTERRA SB150 comes equipped with an adjustable seat attached to an oblique rail system. It can be locked into a position closer or farther to the pedals.
The adjustment bar offers several positions so that the bike can accommodate users between 5’0″ and 6’0″ (153 – 183 cm).
The adjustment system involves a turn-and-pull pin placed on the right side under the seat. For the seat adjustment, the user must not be seated. Both the seat and backrest integrate 2″ (5 cm) of foam padding, delivering optimal comfort.
Their upholstery is a durable vinyl material. The backrest is not adjustable independently from the seat; it has a sturdy backbone and excellent lumbar support.
This XTERRA exercise bike also comes equipped with two handlebars; one connects to the seat assembly and the console mast. The seat handlebars feature a set of stainless steel pulse sensors. In addition, the console can track your heart rate and use the HR-based workout programs by holding on to them.
The front handlebars don’t have pulse sensors but do offer a multi-grip design. In addition, both sets of handlebars are non-adjustable and have rubberized grips for superior comfort and hand adherence.
SB150 Drive and resistance
The XTERRA SB150 integrates an 11 lb (5 kg) flywheel. It’s perimeter-weighted and balanced, delivering a pretty consistent momentum and a smooth pedaling motion. It’s also bi-directional, allowing you to pedal in reverse; however, coasting on this bike is impossible.
The bike’s transmission is belt-driven via a poly-v belt. Therefore, the pedaling motion is almost entirely silent. The belt doesn’t require lubrication. Also, it produces considerably less vibration than a chain drive.
The crank arms are solid steel material. However, being a recumbent bike, standing up on the pedals is not advisable, nor is it comfortable. The included pedals are a durable nylon material. They’re weighted, so they always turn face-up when you remove your feet from them. They also come equipped with adjustable straps to stabilize your feet if needed entirely.
In terms of resistance, the SB150 features an eddy current motorized brake. It consists of a magnetic bracket and a small servo motor. As you adjust the resistance, the motor will move the magnets closer or farther to the flywheel, increasing or decreasing the resistance.
The unit’s resistance system is exclusively digital. This means the resistance is adjustable only from the console. In addition, the bike requires a connected power source to adjust the resistance settings (a power adapter comes included).
Also, the console programs control the bike’s resistance. Thus, if you’re going to use one of the onboard programs, the cycle will auto-adjust the pedal resistance.
There are 24 levels of resistance available. Due to the relatively light flywheel, the first resistance levels are fair, generating minimal impact. Conversely, the top resistance settings can produce a considerably higher difficulty level, simulating a reasonably steep climb.
Although the console does not have Bluetooth functions and is not compatible with any online fitness apps, it offers plenty of features to keep you motivated. First, it features a 3.7″ LCD with a blue LED backlight and significant digits, providing excellent readability.
You can assign target values to time, distance, and calories. This way, the console will count down the selected target value until it reaches zero, rather than showing the elapsed value. Thus, you can create goals to take down for each one of your workouts.
Distance and speed display in English units. Thus, there are no settings for metric units. The console is also not telemetric; it can only measure your pulse rate through the integrated sensors. It doesn’t work with wireless HR chest straps.
SB150 Workout programs
There are several workout programs available on the console. The first (P1) program is the Manual mode. This program allows you to exercise freely, adjusting the resistance manually, as you like, during pedaling from the Up/Down buttons.
The following 12 programs (P2-P13) are preset. To give you an idea of their setup, here’s their name list: Steps, Hill, Rolling, Valley, Fat Burn, Ramp, Mountain, Intervals, Random, Plateau, Fartlek, and Precipice. If one of the preset programs is selected, the bike will auto-adjust the pedal resistance.
The P14-P17 programs are custom programs. Each one allows you to create your program, designing duration and resistance for each segment. In addition, you can save any of the developed programs in the console’s memory.
The P18-P22 programs are heart rate programs. The first four have a preset HR interval; these intervals are 55%, 65%, 75%, and 85%. The fifth program allows you to set your custom HR interval. The bike will automatically adjust the resistance to keep you within the chosen interval when an HR interval program is selected.
There is also Pulse Recovery and a Body Fat function available. The Pulse Recovery function gives you a fitness score between F1 (excellent) and F6 (poor), depending on how much time your heart takes to return to normal after your workout.
The Body Fat function is a unique program that calculates users’ body fat ratio and offers a specific loading profile. It requires you to input data such as height, weight, and gender.
The bike’s console also offers two amenity features. These are the sound system and the tablet holder (or reading rack). The sound system consists of a small speaker placed at the bottom of the console. It is compatible with most smartphones and MP3 players. The sound rendered is not super, but it is louder and more profound than the sound produced by most smartphone speakers.
The tablet holder is right above the speaker. It’s a small shelf that can hold most phones or tablets. However, a tablet placed on it will cover the console buttons and the LCD.
SB150 Assembly and Maintenance
The bike’s assembly is far from being difficult. First, you’ll need to connect the two main pieces of the frame, then attach the two base bars, the console mast, the console, the seat, the backrest, and the pedals.
This shouldn’t take more than an hour. All the assembly instructions come included with the manual. In terms of assembly tools, Allen wrenches come included with the bike.
Maintenance pretty much requires keeping the bike clean and checking its joints periodically. The internal parts do not require lubrication or any maintenance whatsoever.
