XTERRA Fitness MBX2500 Indoor Cycle | Bring Adventure Home

The XTERRA Fitness MBX2500 Indoor Cycle is perfect; whether you’re looking to shed a few pounds or prepare for the bicycling adventure of a lifetime, bring home the training power you need. It doesn’t just look amazing with its sleek styling – the innovative rear drive frame design combines the quality and high performance that XTERRA Fitness has become known for with features that riders of all fitness levels can appreciate.

The main attraction, besides the price, is the XTERRA’s heavy-duty resistance system. A hefty 48.5 lbs precision-balanced flywheel is chrome plated to prevent corrosion and has a protective shield around the outer edge to help avoid touching the moving flywheel during workouts. You can manually shift among eight resistance settings.

Another selling point is the bike’s small size; the machine is under five feet long. Still, the MBX2500 is more massive than most spin bikes (weighs about 105 pounds) and can support a 300-pound rider. In addition, both the saddle and handlebars are adjustable for excellent ergonomics.

For tracking performance, the MBX2500 has an LCD fitness monitor. It has an RPM graphic and simultaneously shows the elapsed time, calorie estimate, distance, speed, and pulse. I also like how the bike is compatible with a wireless heart rate transmitter and provides other exercise feedback.

MBX2500 Frame Construction

XTERRA Fitness MBX2500 Indoor Cycle

The XTERRA Fitness MBX2500 features a steel frame that combines ovalized with round and hexagonal bars. As a result, it has a low center of gravity, which considerably improves its stability. On the other hand, it’s a pretty heavy trainer; it weighs 103.6 lbs (47 kg), which is twice the average mountain bike’s weight, an influence that plays an essential role in its total stability.

Plus, its base bars have adjustable stabilizers. So although it’s a rather heavy exercise bike, its relocation shouldn’t be a problem. The front base also features a set of transport wheels, and by using these wheels when moving the unit, you will handle only approx — 40 % of its total weight.

The bike’s main base bar curves at the rear, improving the unit’s overall sturdiness. It also inclines the user a few degrees forward, which results in a better racing posture with a slightly higher impact on the core muscles.

The belt, crank, and flywheel covers have a durable ABS material. In addition, the middle section between the handlebars tube and the seat tube is highly durable and can be (used) as a stepping pad. Thus, the trainer can support just about any spin workout.

The XTERRA MBX2500 is a bit larger than other spin bikes. With the frame fully assembled, it is 56.3″ (143 cm) long and 20.5″ (52 cm) wide, while its highest point is the top of the console, which reaches approx. 53.2″ (135 cm) above floor level.

The bike’s frame is a corrosion-resistant and abrasion-resistant paint finish. The primary color used is black, with the XTERRA logo painted white. The flywheel, the seat post, and the handlebar post have a chrome finish, though.

Seat and handlebars

The XTERRA Fitness MBX2500 indoor cycle has a spin seat, which is slightly larger and more cushioned than the average slim spin seat. In addition, it features double-stitched, highly durable vinyl upholstery. It also has a longitudinal groove for improved comfort and airflow under the user.

The seat has a standard connection system to its post. Thus, it is quite a plus if you want to replace it, as there are many compatible saddle models in any bike store.

The seat offers 4-way adjustability (up, down, forward, backward). In addition, the upright bar offers ten adjustment positions, while the horizontal slider also provides several inches of front-back adjustment. Therefore, the bike can accommodate users with an inseam up to 38″ (96.5 cm), or differently put, users between 5’0″ and 6’5″ (153 – 196 cm).

Also, in terms of weight capacity, the seat assembly and the whole frame, in general, can support users up to 300 lbs (136 kg).

The bike’s handlebar features a multi-grip design with a loop aero bar in the middle. It offers the possibility to adopt five types of grips and postures. In addition, it’s urethane-dipped for a secure grip and extra comfort.

Just like the seat, the bike’s handlebar assembly offers 4-way adjustability. In addition, its vertical post offers five adjustment positions, while its horizontal slider makes three other fore-to-aft parts available.

MBX2500 Resistance

This XTERRA fitness exercise bike has a manual magnetic resistance system. Therefore, you don’t have to connect it to a power source to adjust resistance. The console is also merely a fitness meter and (is not required) for the bike’s resistance control.

The resistance system consists of a magnetic brake connecting the tension lever on the frame’s top tube through a steel wire. As you press the bar down, the brake increases the internal magnetic field, which results in an increased pedal resistance.

The bike offers eight resistance levels. The flywheel is heavy, so the first resistance level isn’t light. But conversely, the top level of resistance produces quite an extreme pedal tension, which offers the possibility of obtaining a higher muscle burn.

Drive System

XTERRA Fitness MBX2500 Indoor Cycle

There are three main elements to cover here, the flywheel, the crankset with its pedals, and the transmission regarding the bike’s drive system.

The XTERRA Fitness MBX2500 has one of the most massive flywheels available. It weighs 48.5 lbs (22 kg). However, it doesn’t have a perimeter-weighted design, which means it doesn’t deliver highly aggressive inertia, but its weight offers a pretty consistent momentum due to its weight.

It’s also bi-directional so that you can pedal in reverse. This way, you can put plenty of diversity into your workouts.

Just like other spin bikes, the XTERRA MBX2500 features a 3-piece crankset. Its arms are substantial, supporting all users up to 300 lbs (136 kg) in standing-up pedaling routines.

The pedals are metallic alloys. They have standard 9/16 threads, so you can easily find compatible replacements for them if it’s the case. Unfortunately, they do not have SPD clips for spin shoes but have toe cages and straps.

Finally, this trainer features a belt transmission like most other bikes with a magnetic resistance system, and it integrates a heavy-duty v-belt resistant to stretching. As a result, the belt doesn’t need periodic lubrication; instead, a chain drive. It also delivers a smooth pedaling motion with less vibration than a chain.

MBX2500 Fitness monitor

Since the bike’s resistance system is manual, the included fitness monitor doesn’t affect the resistance adjustment. In addition, it doesn’t have any pre-set programs, does not connect online, and is not compatible with any online fitness apps.

The monitor features a 6-window LCD. The top, larger window indicates RPM. The three smaller windows on the left show time, distance, and calories burned, while the right bottom windows indicate pulse and speed.

XTERRA Fitness MBX2500 Indoor Cycle

Countdown settings are available for time, distance, calories, and pulse. You can select a target value for any of these metrics, and the console will count down from the chosen values until it reaches zero. This function lets you set your workout goals and track your progress better.

The bike’s handlebars do not have pulse sensors, but the monitor can track your pulse via an HR chest strap transmitter. This accessory is not included with the bike, though.

The fitness monitor is straightforward to use. It has only two buttons, SET and MODE/RESET. The SET button allows you to set workout goals, while the MODE/RESET button confirms all the settings. For example, you can press and hold the MODE/RESET button for several seconds to clear all the values to zero.

The monitor uses a CR2032 (3V) battery. To start it up, you can press any of the two buttons. It also has a standby mode, starting if the console detects any bike activity for 4 minutes.

MBX2500 Assembly and Maintenance

The core of the bike comes pre-assembled. Next, you’ll have to attach the seat and the handlebar with its post. And lastly, the fitness monitor and the pedals. Therefore, it shouldn’t take more than 30 minutes of your time—the required tools for assembly come with the bike. Also, the manual provides precise assembly instructions.

Since it’s a magnetic resistance bike, its brake doesn’t require any lubrication, nor does the belt. So you only have to keep the unit dust-free and periodically check for loose parts and bolts.

  1. This indoor bike is a little different from the most common since it has the wheel at the back. I don’t know if that could make the bike a bit unstable. What you think about it, or does it make a difference? Apart from that, I think it looks outstanding quality.

    • Hello Hector, thanks for your interest in the XTERRA MBX2500. This bike has a low center of gravity which makes it extremely stable. It also weighs a little over 100 lbs which contribute to its stability.

      Aside from appearance, the main advantage of having the flywheel in the rear is to prevent sweat from dripping down onto it while exercising. Besides, it looks cool!

  2. You’ve written another great review of the Xterra indoor cycling bike. I was slightly concerned about the weight of the cycle compared with other exercise bikes, but with the inbuilt transport wheels that reduce the weight by 40%, it should not be a problem to move it around. 

    I love the fact that one can also pedal backward, as that way, you can also use different muscle groups. It is a serious contender for my home gym as it is an excellent value for the price. 

    • Hi there, 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 MBX2500 bike or any other exercise equipment? I’m always happy to help.

      Kind regards, Robert

  3. You’ve written another excellent review of the Xterra indoor bike. The MBX2500 is perfect for people who don’t have much time for exercise. Having at-home exercise equipment is convenient, saving you on gym memberships and gas, which are expensive now. In addition, you can adjust the seat for the entire family to use. Thank you so much for reviewing like this.

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