Is the XTERRA FB350 Foldable Exercise Bike robust and durable?

The XTERRA FB350 Foldable Exercise Bike measures at dimensions of 50.5” x 20.5” x 20” when folded. Thus, you can easily store it away in your small closet when not needed, which is made more mobile with the built-in transport wheels.

The bike has a robust, X-frame design, which is both minimal and efficient. The frame is thick steel tubing that provides the necessary durability and strength as your exercise.

A fully functional, 2” x 1” LCD helps you keep track of your exercise metrics. It keeps track of the total speed, distance covered, elapsed time, the total number of calories burned, as well as pulse- which is measured by handlebar-mounted pulse sensors.

The FB350 is a well-rounded bike that offers a comprehensive list of features, even for its minimal price tag. It offers eight levels of manual magnetic resistance, giving you ultimate control over varying the intensity of your workout. The magnetic resistance also provides a smooth, fluid, and noiseless operation of the machine.

FB350 Frame construction

The XTERRA Fitness FB350 exercise bike features a durable X-type frame, made of steel tubing. Its central part consists of two parallel tubes slightly curved at the top where the handlebar attaches. The seat bar goes through these two parallel tubes and connects to them in the middle. The drive and resistance elements are attached to the bottom section of the seat tube.

All the steel parts in the bike’s frame are powder coated with a corrosion-resistant finish. The color used is light gray, this being the only color available for this model. The covers of the drive system are ABS material, their colors being blue & gray.

The bike has a folding design. The two main frame elements can be folded together from the middle and locked in a folded or unfolded position via a pop-pin. With the frame folded, the unit’s footprint is approx. 20″ x 21″ (51 x 53 cm), while its height reaches approx. 50.5″ (128 cm).

Conversely, with the frame unfolded, the bike isn’t huge either. Its base takes approx, 31″ x 21″ (79 x 53 cm), but the unit’s full length from the backrest and to the front grips of the handlebar, is approximately 40.5″ (103 cm). Therefore, the bike should fit a minimum usage area of 60″ x 50″ (152 x 127 cm).

The fully assembled bike isn’t too heavy, either. It weighs approximately 42.3″ (19.2 kg). This means it can be transported and assembled by only one person. Plus, once assembled, its relocation is quick and easy via its front transport wheels.

One last aspect to mention here regards the unit’s weight capacity. This XTERRA exercise bike has a maximum user weight of 225 lbs (102 kg). It’s also for seated workouts only; it does not support spin workouts or standing on the pedals.

Seat and handlebars

The bike’s saddle is similar to the one on the FB150 model. It is approx. 14″ (35 cm) wide, and has a contoured surface to provide optimal comfort. It does not integrate air-cell cushioning such as the seat on the Exerpeutic 4000. However, it does have an internal layer of foam padding. Its top is durable vinyl material with a synthetic mesh patch at the rear.

The backrest is attached to a durable, dual bracket. It’s not extremely large but does have a thick layer of foam padding. It provides excellent lumbar support, and can also fold over the seat when the bike is stored.

The seat is 2-way adjustable (up, down). Its post features seven adjustment notches. It’s designed to accommodate users between 4’10” and 5’10” (147 – 178 cm), and up to a weight of 225 lbs (102 kg).

The bike’s handlebar is non-adjustable. It attaches directly to the front part of the mainframe element via two bolts. Its side sections are covered by a layer of rubber foam material to provide a comfortable and secure grip. It offers the possibility to adopt several grips, including parallel grip, close grip, or front grip.

The side grips of the handlebar come with metallic pulse sensors. Therefore, if you hold on to them when pedaling, the console can track and display your pulse rate.

FB350 Drive system

Since it’s a light-capacity exercise bike, the XTERRA Fitness FB350 doesn’t have a super-heavy flywheel. It weighs approx. 3.3 lbs (1.5 kg) and has a balanced design to provide a smooth pedaling motion.

It is also bi-directional, which means it offers the possibility to pedal in reverse. However, you cannot coast on the bike; when pedaling in reverse, the resistance remains constant.

The bike’s internal drivetrain uses a v-belt. Moreover, the pedaling motion is almost entirely silent. It also does not require lubrication as a chain transmission.

The crankset features strong steel arms. The included pedals have a metallic core and a durable, non-slip ABS surface. They’re weighted and also equipped with adjustable straps so that you can secure your feet.

Although the crankset is pretty durable, standing up on the pedals is not recommended. It may lead to excessive internal wear. However, due to the frame design, the position would also be very awkward and may lead to losing balance.

The bike has a pretty narrow Q-Factor (spacing between the pedals). Its exact dimension is not specified, but it should be somewhere between 150-160 mm. Your feet are naturally placed on the pedals, and there isn’t any additional lateral stress on the knees and ankles during pedaling as for bikes with a wider Q-Factor.

Resistance system

The Xterra FB350 exercise bike features a mechanical, magnetic resistance system. Therefore, it does not require an external power source. Also, the console plays no role in the resistance adjustment.

The bike’s resistance system consists of a small magnetic brake that is attached to the dial at the top of the front part of the frame through a steel wire. By turning the dial clockwise, the brake moves closer to the flywheel, which results in an increased pedaling difficulty.

The unit makes available eight levels of resistance. The first one is light, great for recovery training, or warming up. Conversely, the 8th level does provide a distinguishable increased pedal tension, giving you the possibility to reach a higher cardiovascular rate in a shorter time.

FB350 Console

The console offers the same feature range as the one included with the Sunny SF-B2721. It features an LCD with significant digits which tracks the essential workout metrics. Among them, we can count time, distance, total distance, speed, calories, and pulse. The speed is shown only in miles per hour, while distance is in miles; the unit display metric units.

The console is not telemetric. This means it can only read your pulse through the integrated stainless steel sensors. It cannot communicate with Polar or other types of HR chest strap transmitters.

The console is not compatible with any online fitness apps and does not have any preset programs. It also does not have goal settings. It only features one button which covers all of its functions. By pressing the button repeatedly, you can select the desired workout metric on the display.

The Scan Mode rotates all the metrics showing each one for four seconds. It also covers the Reset function; by pressing and holding it for a few seconds, you can clear all the values on the meter to zero.

The unit requires two AA batteries (included) as a power source. It starts up when you press the button, or when you begin pedaling. It also has a sleep mode to which it will enter after four minutes of inactivity on the bike.

FB350 Assembly and Maintenance

The two main parts of the frame come already attached, while the drive and resistance elements are also pre-assembled. Therefore, you only need to connect the bike’s base tubes, the seat, the backrest, the handlebar, the pedals, and the console.

This shouldn’t take more than an hour. The manual provides clear, step-by-step assembly instructions and the necessary tools come with the bike.

Once assembled, maintenance doesn’t require much. You only have to check for loose bolts and parts from time to time. The internal components should not require any lubrication or maintenance for an extended time.

  1. I am intrigued by this bike, because at the moment I use a regular exercise bike for my warm ups, and this one looks like every bikers dream. The best thing about it is that it is foldable, so I would be able to pack it away in my small apartment. My favourite features would be the back pad, the fitness monitor and the wheels to move it around. I also like the feature that makes it operate quietly. For that price, I find it quite reasonable. Thank you for this introduction

  2. This bike seems like a really good option for someone just starting out with exercise who doesn’t want to spend too much money, or someone with limited space. While it does have a lot of good features, its lack of app integration would be the aspect most likely to dissuade me from buying but otherwise it seems like a pretty good product.
