Assault Fitness AssaultBike Pro X Assessment (2023)

The Pro X Assault Bike is among the leading cardiovascular machines currently available. It offers a comprehensive, low-impact training that can still be high-intensity. Well-liked in the CrossFit community, this air bike is comprised of a belt-driven mechanism and a sturdy steel frame, making it an excellent instrument for developing both stamina and power. 

At Breaking Muscle, our specialists consist of athletes, strength and conditioning coaches, and certified personal trainers who are extensively acquainted with this air bike. We subjected it to extensive cardiovascular workout sessions to evaluate its capabilities. In this review of the Assault Fitness AssaultBike Pro X, we will outline our findings, the bike’s performance in testing, and its comparison with other air bikes.

Essential Points

• The ProX Assault Bike is a superb option for individuals aiming for a full-body exercise. This air bike, also known as a fan bike, necessitates engaging in full-body workouts utilizing both the handlebars and bike pedals to create motion through a belt-driven system.
• The LCD monitor monitors parameters such as calories, distance, velocity, watts, and RPM, all of which aid in understanding energy expenditure.
• The Assault Fitness App, accessible via your smartphone and connectible to the bike’s Bluetooth-enabled console, enables participation in virtual and instructor-led programs.

Assault Fitness AssaultBike ProX Advantages

• The Pro X AssaultBike features a seamless belt-driven system to ensure the workout is efficient and less noisy compared to chain-driven air bikes. This makes it a fantastic piece of equipment for a home gym, where noise control can ensure that your workouts do not disturb your roommates or family members.
• With 11 height adjustments and six front-to-back options for customization, the seat can be moved up, down, forward, and backward to suit your body proportions.
• Constructed of a robust steel frame that renders it considerably stable for exercising, the ProX AssaultBike has a weight capacity of 330 pounds, allowing even heavier athletes to use it securely.

Assault Fitness AssaultBike ProX Drawbacks

• Priced at $899 at the time of writing, it is relatively costly and may be unaffordable for those on tight budgets. In contrast, the AssaultBike Classic and the Titan Fan Bike are both priced around $699. 
• The Assault Fitness App, while interactive and an improvement over other brands, has been described as “buggy” in numerous Apple store reviews, resulting in a 2.1 out of 5 star rating.
• The ProX has a considerable footprint, particularly when compared to the AssaultBike Elite. The ProX is 51.73 inches long, 24.52 inches wide, and 52.51 inches high, while the Elite is 50.95 inches long, 23.34 inches wide, and 50 inches high. Depending on your home gym setup, the Pro X may occupy too much space and hinder your ability to safely perform workouts off the bike.

Assault Fitness AssaultBike ProX Score

At Breaking Muscle, we are well-versed in fitness equipment. We have a team of product testers who have extensively evaluated numerous machines, using them for everything from mild warm-ups to high-intensity interval training (HIIT) sessions. Many of our team members are home gym owners who utilize these products on a near-daily basis.

With the knowledge we have accumulated, we developed an exclusive scoring system that we used to assess the ProX AssaultBike across various categories. In addition to evaluating the bike’s individual performance, we conducted comparative assessments with nearly 30 other exercise bikes to gauge its standing against the competition.

Assault Fitness AssaultBike ProX Overview

From the creators of the AssaultRunner (one of the finest treadmills for training), the Pro X Assault Bike is fashioned with a sturdy steel frame finished in a black powder coat that enhances its corrosion resistance and durability. It stands as a top-tier fan bike capable of delivering a strenuous workout for any athlete.

In addition to its robust and enduring frame, it incorporates a belt-driven system for a tranquil, seamless training encounter. It also demands less maintenance compared to chain-driven systems, providing a welcome relief for busy individuals who prefer not to hassle with complex maintenance procedures.

Assault Fitness AssaultBike ProX Comprehensive Evaluation

Price

At present, the Pro X Assault Bike is priced at $899. Fortunately, there is an option to finance it at approximately $82 per month via Affirm. In contrast, the ProX is more expensive than the AssaultBike Classic at $699 but more affordable than the Concept2 BikeErg, priced around $1,100. 

The Pro X Assault Bike also offers complimentary shipping, a significant benefit for equipment of this size. Purchasing an air bike from another brand could incur an additional $100 in shipping expenses.

Considering the above, we have awarded this bike a rating of 4 out of 5 stars for its shipping rate, financing options, and overall value.

Materials, Build, and Construction Quality

The Pro X Assault Bike weighs 125 pounds, has a maximum user weight of 330 pounds, and features a robust steel frame with a black powder coating finish that resists corrosion.  We favor this frame and finish type as it indicates reduced maintenance over time. 

This model closely resembles the Rogue Echo Bike, which exhibits a black powder coating and gives the appearance of being constructed from salvaged materials.The heavy-duty squat rack has been replaced by the robust squat rack! On the other hand, the Rogue Echo Bike, even tho it is not as bulky as the Assault Bike ProX, has a smaller size that our test users found suitable for compact spaces. For instance, the Echo Bike is 55 inches long, 29.5 inches wide, and 52.25 inches high, while the ProX is 51.73 inches long, 24.52 inches wide, and 52.51 inches high.

The ProX is equipped with a broad cushioned seat, which can be adjusted to 11 different heights and six different directions either forward or backward. These same adjustments were present in the Assault Bike Pro, which the ProX supersedes. The rubber grips on the ProX help ensure a steady grip and keep your hands comfortable during the entire workout. 

This air bike also comes with foot supports at the base of the handlebars, giving you the option to perform an upper body-only routine, which is ideal for injury recovery or arm day. 

Due to the quality and structure of the Assault Bike ProX, we granted it a 5-star rating. 

Delivery and Assembly

We bestowed a 5-star rating to the AssaultBike Pro X for delivery and assembly due to its uncomplicated assembly process. The bikes reached our testing facility at 75 percent completion, requiring attachment of the LCD console, pedals, handlebars, seat post, and saddle. Assault Fitness supplies all necessary tools for assembling your air bike, and the process should take around 35 to 45 minutes.

Performance

During the testing of the Assault Bike ProX, we noticed a smoother and quieter ride compared to other air bikes, such as the Titan Fan Bike or the AssaultBike Classic. This is mainly due to the belt-driven system. Unlike a chain-driven system, a belt-driven system demands less maintenance but is more challenging to use. When you pedal, the steel fan wheel creates resistance based on your exertion. The more force you apply while pedaling, the greater the resistance. 

However, when you stop pedaling, the fan wheel halts, requiring more effort to restart it. This may be challenging if you are unprepared for a high-intensity workout. Therefore, we awarded the Assault Bike ProX a 4-star rating for performance. 

Included Workouts

The Assault Bike ProX’s LCD monitor includes seven built-in training programs and a competition mode for those eager for a challenge. The Assault Fitness App, which we’ll discuss later, offers instructor-led programs and the ability to create custom workouts. 

All in all, we have given it a 3-star rating in this category. The included workouts do not match the depth of those in a more interactive bike like the Peloton. Nevertheless, we find them useful, particularly for individuals unsure where to begin. 

Heart Rate Monitoring

While the AssaultBike Classic was only compatible with the Polar T34 heart rate chest strap, the Assault Bike ProX can link to other brands such as Garmin, using its Bluetooth feature. However, a compatible heart rate monitor needs to be purchased separately. Hence, we have given it a 4-star rating here (although this is common for most exercise bikes). 

Display and Stat Tracking

The Assault Bike ProX is equipped with a five-inch by eight-inch monitor, a standard size among other fan bikes. This high-quality LCD monitor operates on four AA batteries, provided by Assault with your purchase, and is excellent for tracking various stats such as calories, distance, heart rate, speed, watts, and RPM. It also connects to the Assault Fitness App. 

Our product testers appreciated the ability to track power output along with distance and speed, offering a great way to quantify workout intensity. The Rogue Echo Bike monitor lacks feedback such as watts and RPM, giving the Assault Bike ProX an advantage. 

All things considered, we awarded this bike a 5-star rating for its display and tracking capabilities. 

Conveniences

During testing, we discovered several conveniences with the Assault Bike ProX. Firstly, it requires no electrical outlet, providing the flexibility to use it anywhere. This feature is advantageous for commercial CrossFit gym owners as it prevents concerns about members tripping over power cords. 

Other conveniences include a device holder and a water bottle holder, features also found in some fan bikes like the Titan Fan Bike. However, they are not available on bikes such as the Rogue Echo Bike, although they can be purchased separately. We appreciate the addition of these little extras, making all your workout essentials easily accessible. The only reason we deducted a point is that we wished the bike included a wind guard to prevent cold air from blowing in our faces when training in a cold garage. It is available to purchase separately for an additional $39. Our testers rated the conveniences 4 out of 5 stars. 

Workout Apps and Subscription Options

The Assault Bike ProX is part of the Assault Fitness line of workout machines that utilize the Assault Fitness app. The app is one of our product testers’ favored features. 

Available for free download from the App Store and Google Play, the Assault Fitness App presents a variety of instructor-driven workouts. Users can perform these workouts alone or virtually compete against other athletes. Many workouts also integrate different types of equipment, such as dumbbells and kettlebells, enhancing the overall programming. 

Although we enjoyed the app, we only awarded it 4 out of 5 stars since, at the time of this writing, it is not available on the latest version of Android. Users with newer Android phones might encounter compatibility issues. 

Bluetooth Connectivity

The Assault Bike ProX features Bluetooth connectivity. While we do not consider this a standout feature, as numerous cardio equipment includes this functionality, it remains a useful addition. 

A number of the machines we have tested now come with it. Nonetheless, we have also experimented with low-priced cardio equipment lacking this feature, and even Assault Fitness’s classic AssaultBike doesn’t possess Bluetooth capabilities. Consequently, we awarded the ProX 5 out of 5 stars here.

Noise Level

When comparing other fan bikes we assessed, the Assault Bike ProX produced lesser noise due to its belt-driven system. The belt-driven system functions more smoothly than chain-drive systems, such as those on the Schwinn Airdyne. A noisier system can make it challenging to carry out workouts at home, especially if you exercise early in the morning or late at night when others are asleep.

That being said, no fan bike can be completely noiseless, so some noise should still be expected as air circulates through the flywheel. For this reason, we rate the noise level of the Assault Bike ProX at 4 out of 5 stars.

Portability

The Assault Bike ProX offers some mobility, courtesy of two small transport wheels at the front. To relocate it, simply tilt it onto its wheels to effortlessly slide it across the floor. Nevertheless, while it might be effortless for a few athletes to transfer this fan bike, others might encounter difficulties owing to its 125-pound weight. Based on these observations, we rate the portability of the Assault Bike ProX at 4 out of 5 stars.  

Warranty

The Assault Bike ProX comes with a three-year warranty for non-wear parts and a seven-year warranty for the frame. The three-year warranty for non-wear parts does not cover normal wear and tear on elements like the seat, pedals, and handle grips. This might appear as a downside, but in our experience, this is standard in warranties for fan bikes from other brands. Nevertheless, the duration of Assault’s warranty is lengthier when compared to Rogue, who only provides a two-year warranty on their Echo Bike, and Titan, who only offers a one-year warranty on their fan bike. We awarded 5 out of 5 stars to the warranty of the Assault Bike ProX for this reason.

Assault Fitness AssaultBike ProX Specs

Overall Dimensions

The Assault Bike ProX measures 51.73 inches in length, 24.52 inches in width, and 52.51 inches in height. In comparison to the classic AssaultBike, these dimensions are larger by one to two inches in each category. If you are torn between the two, we highly recommend ensuring that you measure accurately to select the one that suits your space best.

Resistance

The Assault Bike ProX is a fan bike, whereby the resistance builds up based on the amount of air you draw in the fan wheel during your workout. The more vigorously you pedal, the greater air resistance is exerted, intensifying your workout. 

In addition to air resistance, the ProX utilizes a belt-driven system, meaning it only engages when you start pedaling. If you cease pedaling, the machine ceases movement. This makes it more challenging to operate compared to a chain-driven system, such as what is seen with the AssaultBike Classic. 

Weight Capacity

The weight capacity of the Assault Bike ProX is 330 pounds. This is higher than the capacity of the Classic bike, which supports 300 pounds, but lower than that of the Elite, which accommodates up to 350 pounds. 

Seat and Handlebar Adjustments

The Assault Bike ProX can cater to most body sizes with 11 different height settings and six front-to-back settings. These adjustment levels are quite standard based on our observations of other fan bikes. However, some rivals like the Rogue Echo Bike only offer five front-to-back seat settings. 

Electrical Requirements

Since the Assault Bike ProX does not necessitate an electrical outlet, you can relocate it wherever you desire — indoors or outdoors. However, the monitor does require AA batteries to function. 

Assault Fitness AssaultBike ProX vs. Echo Bike

Initially, it appears that the Assault Bike ProX and Rogue Echo Bike share numerous similarities. Examining them in-depth, however, reveals several fundamental disparities between the two. 

Below are the dimensions of both fan bikes:

Although the Rogue Echo Bike uses bulkier materials and has larger dimensions, it shares the same 330-pound weight capacity as the AssaultBike ProX. Furthermore, both these fan bikes are movement-powered, therefore not needing an electrical outlet. Also, weighing in at 123 and 125 pounds, respectively, the Rogue Echo Bike and the Assault Bike ProX are equally portable, particularly considering they both have wheels.

Lastly, both products utilize belt-driven mechanics, providing a smooth and noiseless riding experience. Nonetheless, the Assault Bike ProX offers more metrics on the monitor, including watts and RPM. This feature alone could be a deciding factor, depending on how critical tracking is in your training.

Assault Fitness AssaultBike ProX Customer Reviews

The Assault Bike ProX holds a solid 4.6 out of 5-star rating on the Assault Fitness website. Numerous users assert that it is remarkably straightforward to set up, demands minimal maintenance, and stands out as a top choice in their home gyms. Customers also commend its durability and its capability to withstand intense workouts. 

One user reported that the left peg became loose during their workout. Another buyer mentioned that the AssaultBike ProX was notably loud and did not seem to be as steady as indicated in other reviews — it’s worth noting, however, that grievances of this nature are in the minority.

Overall Assessment: Is the Assault Fitness AssaultBike ProX Worth the Investment?

Following thorough examination and trials of the Assault Bike ProX, we can confirm that this air bike is indeed worth considering. Constructed with a robust steel frame finished in a black powder coating, it can handle the most challenging workout sessions. It is perfect for individuals seeking a full-body, high-intensity interval training device to enhance both endurance and strength. 

The smoother and quieter operation achieved with the Assault Bike ProX is attributable to the belt-driven system seamlessly incorporated into its design. Despite the potential increased exertion required by this system, this bike can still be an excellent investment for CrossFitters and fitness enthusiasts alike.
