Assault Fitness AssaultBike Pro X Review (2024)

The Assault Bike ProX is one of the best cardio machines currently offered, as it provides a full-body, low-impact workout that can still be high-intensity. Popular in the CrossFit community, this fan bike consists of a belt-driven system and a heavy-duty steel frame, making it a great tool to build both endurance and strength. 

Here at Breaking Muscle, our experts include athletes, strength and conditioning coaches, and certified personal trainers who are intimately familiar with this fan bike. We put it through hours of strenuous cardio workouts to see if it could take on the challenge. In this Assault Fitness AssaultBike Pro X review, we’ll highlight our results, how well the bike ranked in testing, and how it compares to other fan bikes. 

Key Takeaways

• The Assault Bike ProX is a great choice of cardio equipment for those who want a total-body workout. This fan bike, also termed an air bike, requires you to engage in full-body exercise using both the handlebars and bike pedals to generate movement through a belt-driven system.
• The LCD monitor tracks stats such as calories, distance, speed, watts, and RPM, all of which can help you understand energy output.
• The Assault Fitness App, which you can access through your phone and connect to the bike’s Bluetooth-enabled console, allows you to take part in virtual and instructor-led programming.

Assault Fitness AssaultBike ProX Pros

• The AssaultBike Pro X features a smooth belt-driven system to keep the workout efficient and quieter than chain-driven fan bikes. This makes it a great piece of equipment for a home gym, where limiting noise can ensure your workouts aren’t a nuisance to your roommates or family members.
• With 11 height settings and six front-to-back settings for adjustments, the seat can move upward, downward, forward, and backward to help accommodate your body proportions.
• Made of a heavy-duty steel frame that makes it pretty stable for exercise, the AssaultBike ProX has a weight capacity of 330 pounds, so even heavier athletes can safely use it.

Assault Fitness AssaultBike ProX Cons

• Running at $899 at the time of this writing, it’s relatively expensive and may be out of reach for those with tight budgets. In comparison, the AssaultBike Classic and the Titan Fan Bike are both around $699. 
• The Assault Fitness App, although interactive and a step up from other brands, has been termed “glitchy” through the many reviews at the Apple store. As such, it only has a a 2.1 out of 5 star rating.
• The ProX has a large footprint, especially 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 take up too much room and prevent you from doing workouts off the bike safely.

Assault Fitness AssaultBike ProX Rating

At Breaking Muscle, we know exercise equipment. We have a product testing team that has put hundreds of machines through the wringer, using them for everything from gentle warm-ups to high-intensity interval training (HIIT) workouts. Many of our staff members are home gym owners themselves and use these products nearly every day.

With the knowledge we’ve gained over the years, we created a proprietary scoring system that we used to rank the AssaultBike ProX in various categories. Not only did we evaluate how the bike performed on its own, but we also compared it with nearly 30 other exercise bikes to see how it stacked up against the competition.

Assault Fitness AssaultBike ProX Overview

From the founders of the AssaultRunner (one of the best treadmills to train with), the Assault Bike ProX is made with a heavy-duty steel frame finished in a black powder coat that helps keep it corrosion-resistant and capable of standing the test of time. It is a top-tier fan bike that can provide a brutal workout for any athlete.

In addition to its tough and durable frame, it incorporates a belt-driven system for a quiet, smooth training experience. It also requires less upkeep than chain-driven systems, which should come as a relief to busy individuals who can’t be bothered with complicated maintenance protocols.

Price

At the time of writing, the Assault Bike ProX costs $899. Fortunately, there is also an option to finance it at around $82 a month through Affirm. For comparison, the Assault Bike ProX is more expensive than the AssaultBike Classic at $699 but cheaper than the Concept2 BikeErg, which costs around $1,100. 

The Assault Bike ProX also provides free shipping, which is a big deal for equipment this size. Buying an air bike from another brand could set you back another $100 in shipping costs.

All of the above considered, we’ve rated this bike 4 out of 5 stars for its shipping rate, finance options, and value.

Materials, Build, and Construction Quality

The Assault Bike ProX weighs 125 pounds, has a max user weight of 330 pounds, and boasts a heavy-duty steel frame with a corrosion-resistant black powder coating finish.  We love this type of frame and finish because it means less maintenance over time. 

It’s also similar to what you would see with the Rogue Echo Bike, which has a black powder coating and almost looks like it was built from scraps of a heavy-duty squat rack! But the Assault Bike ProX isn’t as bulky as the Rogue Echo Bike, making it more compatible with small spaces, which our product testers enjoyed. For comparison, the ProX is 51.73 inches long, 24.52 inches wide, and 52.51 inches high, while the Echo Bike is 55 inches long, 29.5 inches wide, and 52.25 inches high.

The Assault Bike ProX provides a wide padded seat that can adjust to 11 different heights and six different directions either forward or backward. These adjustments were the same on the Assault Bike Pro, which the ProX replaces. The rubber handles on the ProX help you maintain…
