XTERRA FB150 Upright Bike | Convenient Folding Design

The XTERRA FB150 Upright Bike has a sturdy and durable X-frame that can carry a maximum user weight of 225 pounds and folds down to only 18 x 18 x 50.5 inches; when you’re not using it, roll it on its transport wheels to free up space. It is a good option for burning calories, losing weight, and getting in shape, but you don’t have much space.

The 3.3-pound precision-balanced flywheel has frictionless magnetic resistance and a silent belt drive system, so you can pedal smoothly and quietly without needing maintenance. It is a quiet bike, and you won’t disturb people in the house or your neighbors downstairs.

The XTERRA FB150 features a fitness monitor that’s easy to read and use, as it offers you feedback with stats like time, distance, calories, speed, and pulse. In addition, the Scan function lets you see these indicators one by one without pressing a button.

The FB150 is a comfortable exercise bike with a large, ergonomic contoured, thick-padded seat and multi-grip padded handles. Both of which offer you support and comfort during lengthy workouts. People between 4’10” and 5’10” can comfortably ride this bike as the seat can be set pretty low, close to the pedals.

FB150 Frame Construction

The XTERRA FB150 features a two-piece frame with an “X” structure; the two connect in the middle. Although the bike’s frame is steel, the whole unit is relatively light; it weighs only 32 lbs (14.5 kg) with the fully assembled frame. In addition, the front base bar has small wheels that facilitate the unit’s relocation.

XTERRA FB150 Upright Bike

This XTERRA upright bike isn’t giant. With the frame fully assembled, it is approx. 31.5″ (80 cm) long and 18″ (46 cm) wide, while its highest point is given by the handlebars, reaching approx—50.5″ (120 cm) above floor level. The frame also folds to save space; with it folded, the unit’s footprint becomes 18″D x 18″W (46 x 46 cm).

It is advisable to leave at least two feet of clearance on each side of the bike and at least one foot at the front and rear for easy access and safe operation.

The bike’s rear base is a straight bar, not curved like other bikes. The cycle doesn’t have a reinforcement bar for the seat, so its maximum weight capacity is only 225 lbs (102 kg).

One last aspect to note here regards the unit’s paint finish. All its metallic parts come with a gray, rust-resistant, chip-resistant paint finish. In addition, the ABS covers of the flywheel and drive belt are blue.

Seat & handlebars

The XTERRA FB150 comes equipped with an extra-large seat. It’s approx. 14″ (35 cm) at its widest point; therefore, its comfort accommodates users of all sizes as long as they don’t exceed the maximum user weight capacity of 225 lbs (102 kg). The seat integrates a layer of padding to provide optimal comfort. Also, its top is made of durable, thick vinyl material.

If you’re wondering, the seat doesn’t have the typical collar design like most bike seats. Instead, its post features a triangular plate at the top to which the seat attaches via three bolts. It is replaceable, and seats with this attachment system are available for sale, so it is possible to find a replacement if you want a different seat type.

The seat is only two-way adjustable (up, down). Its post features seven adjustment positions. Thus, the bike accommodates users between 4’10” and 5’10” (147 – 178 cm), promoting a complete leg extension.

The bike’s handlebars are non-adjustable. Instead, their metallic, curved bar attaches to the front part of the frame via two bolts. The handlebars have a multi-grip design, and a layer of rubber foam covers them for a secure grip. In addition, they also integrate stainless steel pulse sensors so the fitness monitor can track your heart rate.

FB150 Resistance system

The XTERRA FB150 upright bike features a manual magnetic resistance system. A steel wire integrates a small magnetic brake attached to the dial at the top of the frame’s front.

The brake’s position on the flywheel changes by turning the dial clockwise or counterclockwise, which results in an intensity shift of the internal magnetic field, leading to more or less pedal resistance.

Since the bike’s resistance system is manual, you do not have to connect it to a power source. Also, the monitor doesn’t play any role in the bike’s resistance adjustment.

There are eight levels of resistance available. The first one is light, great for recovery training or warming up. Conversely, the 8th level does provide a different pedal tension, but it’s still pretty weak. The bike is not for highly intense muscle burning like spin or heavy-duty upright bikes.

Drive system

Since the bike features a magnetic resistance system, it has a belt drive system. Therefore, the pedaling motion is very smooth and quiet. In addition, the bike doesn’t require any lubrication.

The integrated flywheel is very light, as well. It weighs 3.3 lbs (1.5 kg) and doesn’t provide highly aggressive inertia or strong momentum. In addition, it’s bi-directional, so you can pedal reverse to add diversity to your workouts. When pedaling in reverse, the fitness monitor will track your distance traveled, calories burned, etc.

The bike has a solid, 3-piece crankset featuring steel crank arms. The included pedals have a metallic core and a durable, non-slip ABS surface.

They’re weighted, which means they always turn face-up when you remove your feet from them. Furthermore, they also come equipped with adjustable straps to secure your feet. And finally, they have standard threads, so you can easily find replacements if you wish to replace them.

Since it’s a small bike, the XTERRA FB150 also has a narrow Q-Factor (spacing between the pedals). Its exact dimension is not specified, but it should be between 150-160 mm.

Therefore, your feet are positioned correctly on the pedals. Unfortunately, this doesn’t allow additional lateral stress on the knees and ankles during pedaling, like bikes with a wider Q-Factor.

FB150 Fitness monitor

The XTERRA FB150 includes a fitness monitor. Furthermore, other trainers do not have a fitness monitor, so this accessory is a plus. The monitor features an LCD indicating speed, distance, total distance (ODO), time, calories burned, and pulse.

It has a SCAN function that rotates all the fitness metrics, keeping each one on-screen for several seconds, but you can also select one to view at all times if you want. You will have to hold onto the pulse sensors integrated into the handlebars to track your pulse. Unfortunately, the monitor is not telemetric.

The fitness monitor is pretty easy to use and has only one button. It turns on when you push the button or detect flywheel movement. The monitor will rotate the values showing each for several minutes by selecting the SCAN function. However, you can choose any of the values to be on display at all times.

Finally, the fitness monitor is battery-powered. It uses two AA batteries, which come included with the bike. It also has a sleep mode to enter after several minutes of inactivity on the bike.

FB150 Assembly & Maintenance

The bike’s mainframe is pre-assembled, with the flywheel, crank, belt, and resistance system attached to the frame bar. Therefore, you only need to connect the seat post, the seat, the handlebars, the two bases, the pedals, and the fitness monitor.

Therefore, it shouldn’t take longer than 40-45 min of your time. The manual provides clear assembly instructions, and the necessary tools come included with the bike.

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, for maintenance, you’ll need to wipe the dust from the frame, periodically check for loose parts and bolts, and retighten if necessary.

  1. Upright and recumbent bikes are on the increase in home gyms to running machines. They take up less space meaning more people can fit them in their homes. The other positive aspect of upright bikes is that they are not weight-bearing. The people using them are less likely to injure their joints.

  2. I have a passion for maintaining my weight and figure. This upright bike is ideal for losing weight. This will be a welcome addition to aerobics. I love the fact that it can fold away saving space. And its LCD screen encourages the user to exercise more, seeing the steady daily progress displayed. 

    • Hi Juliet,

      Are you in need of a bike? This XTERRA FB150 is very affordable and as you said it’s ideal for weight loss. If I can be of any help to you just let me know.


  3. I have been looking for an exercise bike that does not need a power supply connected to make it work, and the Xterra FB150 bike might be the answer. The magnetic drive system makes it quiet, and the eight resistance levels should provide enough of a workout without straining the muscles.

    The fact that it folds away into a very compact size makes the XTerra FB150 perfect for anybody living in a small space to store it away when not in use quickly. 

    • Hi there, thanks for stopping by and sharing your thoughts with us. Would you please let me know if I can assist you with the XTERRA FB150 or any other exercise equipment? I’m always happy to help.

      Kind regards, Robert

  4. The features on the Xterra FB150 are pretty good for such a small machine. I am getting older, so the light weight of 32 pounds is great. We spend a great deal of time in a relatively small motor home. This machine will fold easily and fit into a storage compartment, not adding much weight to our motor home. I have never used a machine with a magnetic drive, but friends have told me it is incredibly smooth. The price is not bad either. I am going to show this to my wife. It’s a piece of equipment I would like to carry with us.

    • Hi Collins, thanks for stopping by and sharing your thoughts with us. Would you please let me know if I may further assist you with the XTERRA FB150 bike or other exercise equipment? I’m always happy to help.

      Kind regards, Robert

  5. Hello!  Thank you for the comprehensive review!  I like that this bike can be folded down and stored away.  One thing that I wish this bike had was adjustable handlebar height.  As someone short, I worry that it would be higher than comfortable.  Do you have a recommendation for a similar bike that would be good for shorter people?

    • Hi Danielle, thanks for stopping by and sharing your thoughts with us. XTERRA rates this bike for users between 4’10” and 5’10”. Sorry, but I don’t know of any cycle for shorter users.

      Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert
