XTERRA MBX2500 Indoor Cycle | Perfect for Cardio Workouts

The XTERRA MBX2500 Indoor Cycle by XTERRA Fitness is among the lower-priced choices for cycle training at home. Sells for around $500 when on sale, this sturdy ride costs far less than this year’s premium spin bikes.

The main attraction, besides the price, is the XTERRA’s heavy-duty resistance system. A 48.5-lb wheel supports quite smooth pedaling, and 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 heavier than most spin bikes (it weighs about 105 pounds) and can support a 300-pound rider. Both the saddle and handlebars are adjustable for excellent ergonomics.

For tracking performance, the MBX2500 has a small LCD 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

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

Plus, it’s base bars have adjustable stabilizers. 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 covers of the belt, crank, and flywheel has a durable ABS material. 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 a bit larger and more cushioned than the average slim, spin seat. It features a 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. This is quite a plus in case you want to replace it as there are many compatible saddle models in just about any bike store.

The seat offers 4-way adjustability (up, down, forward, backward). 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. It’s urethane-dipped for a secure grip and extra comfort.

Just as the seat, the bike’s handlebar assembly offers 4-way adjustability. Its upright post offers five adjustment positions, while its horizontal slider makes available three other fore-to-aft positions.

MBX2500 Resistance

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

The resistance system consists of a magnetic brake which connects through a steel wire to the tension lever on the main tube of the frame. 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. Considering that the flywheel is pretty heavy, the first level of resistance isn’t exactly light. Conversely, the top level of resistance produces a quite extreme pedal tension, which offers the possibility to obtain a higher muscle burn.

Drive System

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

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. This means it doesn’t deliver highly aggressive inertia, but due to its weight, it does offer a pretty consistent momentum.

It’s also bi-directional, so you can pedal in reverse if you want. 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, being able to support 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. They do not have SPD clips for spin shoes, but they do have toe cages and straps.

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

MBX2500 Console

Since the bike’s resistance system is manual, the included console doesn’t play any role in the resistance adjustment. It doesn’t have any pre-set programs, does not connect online, and is not compatible with any online fitness apps.

The console 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.

There are countdown settings 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 particular function allows you to set up goals for your workouts, and keep a better track of your progress.

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

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

The console uses a CR2032 (3V) battery. To start it up, you can press any of the two buttons. It also has a standby mode which starts if the console doesn’t detect any activity on the bike for 4 minutes.

MBX2500 Assembly and Maintenance

The core of the bike comes pre-assembled. You’ll have to attach the seat with its post, the handlebar, with its post. And lastly, the console, and the pedals. This shouldn’t take more than 30 minutes. The required tools for assembly (are included). 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. 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!
