XTERRA Fitness FB150 Folding Exercise Bike: Rated & Reviewed

Low impact, high intensity cardio equipment is ideal for losing body fat, boosting endurance, and improving overall health while keeping your joints in good shape. One of the best machines that fit these specifications is the exercise bike.

With countless models to choose from, the XTERRA Fitness FB150 Folding Exercise Bike holds strong in the top ranks due to its comfort, quality, versatility, and more. Don’t go anywhere if you want to know everything about how the FB150, because our guide has everything you need!

Durable Build Quality

As you may already know, one of the most durable materials in the world is steel. The 2-piece X-frame, which makes up the bulk of the XTERRA Fitness FB150 Folding Exercise Bike, is made of exactly that.

Despite being so durable, it’s actually pretty light and easy to move around. All metals are finished with a rust-resistant, chip-resistant paint to ensure that no sweat or regular usage diminishes the quality. Even the pedals come comprised of 3 pieces for added resilience.

Compact Footprint

When fully assembled, the bike is still incredibly compact – even when you’re using it. If you’re tight on space, it’s hard to find a better option than this XTERRA bike.

Portability and Storage

On the front base bar, you’ll find a set of wheels that make it easy to tip the bike and roll it around wherever it needs to go. If you need to stow it away, it’s easy to fold it up into an even more compact size to fit in a closet, behind a door, in a corner, etc.

EKG Sensors

With pulse sensors on each side of the handlebars, you can measure your heart rate. Of course, they’re not as accurate as, say, a heart rate strap around the chest, but they’re better than nothing and give you an idea of how you performed throughout the workout.

Magnetic Resistance Options

With a manual magnetic resistance system, you can adjust difficulty simply by turning the dial clockwise or counterclockwise. You get 8 resistance levels in total, which is more than enough for accomplishing an array of fitness goals.

Contoured Seat

The extra-large seat comes with a thick layer of padding contoured to fit the natural curves of your body instead of working against it. If you’re someone who likes extended cycling sessions, you’ll appreciate this comfy addition.

Easy Assembly

Thankfully, the bike’s main frame comes pre-assembled. That means all you have to do is attach the seat post, seat, handlebars, bases, pedals, and console. If you do it yourself, it shouldn’t take you more than an hour.

Narrow Q-Factor

The Q-Factor (essentially the space between the pedals) on the FB150 is quite narrow, which allows the knees to move in a more natural path. This creates much less stress on the hips, knees, and ankles while pedaling, making it a more logical choice for long-term use and those who have joint issues already.

Comfort, convenience, affordability, real results, and much more is what you’ll find in the Xterra FB150 Folding Bike. While it’s not the most technologically advanced out there, it will help you tone up, improve your health, and clear your mind. If you’re tight on budget or space, you’d be hard-pressed to find a better option than this.

While there's often a direct correlation between price and quality, you'll find that this upright bike breaks all the rules. Made of steel, the X-type frame is incredibly durable and made to support up to 225 pounds, which is pretty impressive for a bike that weighs a mere 32 pounds. To seal in its reliability, it even comes with a rust-resistant, chip-resistant finish.

As you can imagine, the lightweight model is incredibly easy to transport – both inside the house and outside. The built-in wheels in front only facilitate this! One of the biggest reasons people head for the FB150 before any other is its small footprint.

The bike is incredibly easy to fold up and does so with not much more than a push of a lever, so when you're done, you can stow it away without it taking up any room in your home.

Often, smaller bikes end up being stingy on comfort with smaller seats and awkward angles. That isn't the case at all here. Featuring an extra-large seat, it's made to accommodate users of various sizes. With a thick padding and anatomical design, it works with your body's natural curves to ensure your comfort, even during longer cycling sessions.

Covered with a thick vinyl, you don't have to worry about it ripping or wearing down, either. To ensure ergonomics and safety, there are 7 adjustment positions (up and down) to accommodate riders who stand anywhere from 4'10" to 5'10" tall.

Unfortunately, the handlebars are not adjustable, though they feature a multi-grip design with a rubber foam covering for extra grip and comfort. Here, you'll also find stainless steel pulse sensors built in to track your heart rate.

A smooth and efficient ride is guaranteed with the manual magnetic resistance system of the Xterra FB150. To adjust the resistance difficulty, simply turn the integrated dial at the top right or left. You have 8 difficulty levels, which isn't the most but sufficient for the vast majority of riders to continue seeing results in every physical aspect.

A built-in flywheel helps create a smooth riding experience, allowing you to pedal either forward or backward for maximum mobility and results (addressing the hamstrings/quads more equally).

The bike doesn't lack anywhere in quality – even with the pedals. Featuring 3-piece steel crank arms, a metal core, and non-slip ABS footplates, you can pedal hard without feeling like your feet are going to slip off. The adjustable straps will help keep them in place, too.

Finally, to track your progress, you have a straightforward, battery-powered fitness meter. It's not backlit, but it does include an LCD display to track speed, distance traveled, total distance, time, calories burned, heart rate, and scan.

Comparing Different XTERRA Folding Exercise Bikes

You may see other XTERRA Fitness folding bike models and wonder if the FB150 is right for you. Let’s make this easy and compare it with the other 3 most popular to ensure you make an educated decision.

XTERRA Fitness FB150 vs. XTERRA Fitness FB160

XTERRA Fitness FB160

XTERRA Fitness FB160

  • Easy-to-use folding frame design
  • Quiet, smooth lower-body workout
  • Built-in accessory tray holds a phone, tablet, or book
  • Multi-position padded handlebar, padded seat, and oversized foot pedals

First off, the FB150 is just a tiny bit more affordable than the FB160. They’re almost identical, aside from the fact that the LCD display is slightly more advanced and comes complete with an integrated accessory tray for your smart devices on the FB160. The flyweight system is also a couple of ounces less heavy, though this didn’t make much of a difference.

XTERRA Fitness FB150 vs. Xterra Fitness FB350

Xterra Fitness FB350

Xterra Fitness FB350

  • Easy-to-use folding frame design
  • Quiet, smooth lower-body workout
  • Anatomically designed thick padded seat with back
  • 8 levels of resistance

The FB350 is a bit more expensive, and while there are many similarities, there are also notable differences in the seat area. For example, the FB350 comes with a seat back, seat handles, accessory handles, and pulse grip handles. It is a bit larger, though, so it isn’t quite as convenient if you’re tight on space. Aside from that, you can expect essentially the same bike for a slightly higher price.

XTERRA Fitness FB150 vs. XTERRA Fitness FB360

XTERRA Fitness FB360

XTERRA Fitness FB360

  • Large, adjustable padded seat with supportive seat back
  • Easy-to-use folding frame design
  • Quiet, smooth lower-body workout
  • Built-in accessory tray holds a phone, tablet, or book

Just like the others, the FB360 is the more expensive of the two. This is because it includes an adjustable seat back, seat handles, and a built-in accessory tray to hold your book, phone, tablet, etc.

Circuit Fitness' AMZ-150BK is similar but a bit less stable than the FB150. It features very narrow steel tubing, making it more ideal for slow and steady pedaling than intervals or hills.

So, if you’re wondering, "Are Xterra bikes good?" the answer is a definite "yes"! They are affordable, sturdy, versatile, smooth, and reliable.

XTERRA Fitness FB150 Folding Bike Assembly

Assembly is very straightforward, and you'll find everything you need in the original package. The frame is already pre-assembled, so it will take no more than 45 minutes, realistically speaking. However, it's crucial that you pay particular attention that everything is assembled correctly as the frame itself is light and not stable on its own.

In particular, you'll want to make sure the stabilizer tubes in the front and rear are evenly and securely tightened. The seat tube should also be inserted correctly but should never be forced. This is a nice video covering unboxing and assembly from beginning to end (assembly for the FB150 and FB350 is almost identical).

People Also Ask (FAQs)

How do you increase resistance on the Xterra Fitness FB150 Bike?

All you have to do is turn the dial to the right/clockwise.

Bicep curls and tricep extensions are big ones with the FB150. Grab yourself a pair of resistance bands and loop them under the bike, or loop one around the handlebars for some seated rows. This ensures that you work your upper and lower body at once, burning max calories.

How do Xterra FB150 folding bikes compare to other cardio equipment?

You should always wipe it down with a soft cloth damp with a soap/water mix and make sure you dry it properly as well. This is to get rid of any sweat/bacteria that accumulates naturally from use. Make sure it’s always properly oiled, just as it will arrive to you.

Where to buy XTERRA Fitness folding bikes?
