Assault Fitness AssaultBike ProX In-Depth Review:
Price:
Priced at $899, the Assault Bike ProX represents a significant investment. However, financing options are available through Affirm, with monthly payments around $82. This positions the ProX above the AssaultBike Classic ($699) but below the Concept2 BikeErg ($1,100). A notable financial benefit is the inclusion of free shipping, a considerable saving for equipment of this size and weight.

Materials, Build, and Construction Quality:
Weighing 125 pounds and supporting a maximum user weight of 330 pounds, the Assault Bike ProX is engineered with a heavy-duty steel frame and a durable black powder coating, enhancing its resistance to corrosion and wear. This construction is reminiscent of high-performance gym equipment, such as the Rogue Echo Bike, known for its rugged build. However, the ProX offers a more compact footprint, measuring 51.73 inches in length, 24.52 inches in width, and 52.51 inches in height, making it more adaptable to smaller training spaces. The seat provides ample cushioning and offers extensive adjustability, with 11 height settings and six directions of fore-aft movement, mirroring the versatility of its predecessor, the Assault Bike Pro. The rubberized handlebars ensure a secure and comfortable grip during intense workouts. A key design feature is the inclusion of footpegs on the handlebars, enabling users to isolate their upper body for targeted training, beneficial for recovery or specific arm-focused sessions. Based on its superior materials, robust construction, and thoughtful design elements, the ProX receives a perfect 5 out of 5 stars for build quality.
Delivery and Assembly:
The Assault Bike ProX is designed for user-friendly assembly, arriving approximately 75% pre-built. This significantly reduces the time and effort required for setup. Users need only attach the LCD console, pedals, handlebars, seat post, and saddle. Assault Fitness includes all necessary tools, and the assembly process typically takes between 35 to 45 minutes. This streamlined approach contributes to a positive initial user experience, earning it a 5 out of 5 stars rating for delivery and assembly.
Performance:
The ProX distinguishes itself with a notably smoother and quieter ride compared to other fan bikes, such as the Titan Fan Bike or the AssaultBike Classic. This enhanced performance is primarily attributed to its belt-driven system, which not only minimizes noise but also requires less maintenance than chain-driven alternatives. The resistance mechanism is dynamically responsive, with the steel fan wheel generating increased resistance as the user pedals harder. This design ensures that the intensity of the workout directly correlates with user effort. However, the inertia of the fan wheel means that once pedaling ceases, the wheel stops, requiring more effort to re-engage momentum. This characteristic can present a challenge for individuals unaccustomed to high-intensity interval training (HIIT), demanding a higher level of exertion to initiate and sustain a workout. Consequently, the Assault Bike ProX is rated 4 out of 5 stars for performance, acknowledging its exceptional smoothness and responsiveness while noting the demanding nature of its resistance system for less experienced users.
Included Workouts:
The ProX’s LCD monitor features seven pre-programmed training sessions and a competition mode, offering a foundational set of workout options. Furthermore, integration with the Assault Fitness App unlocks access to instructor-led programs and the ability to create custom workouts. While these built-in programs are beneficial for users seeking guidance, they are not as extensive or interactive as those found on more technologically advanced bikes like the Peloton. Nonetheless, their inclusion provides a valuable starting point for individuals new to fan bike training. The rating for included workouts is 3 out of 5 stars, reflecting their utility but acknowledging the availability of more comprehensive digital fitness platforms.
Heart Rate Monitoring:
A significant upgrade from the AssaultBike Classic, the ProX supports Bluetooth connectivity for heart rate monitors from various brands, including Garmin, in addition to the Polar T34 chest strap. This enhanced compatibility allows users to integrate their preferred heart rate tracking devices seamlessly. Although a compatible monitor must be purchased separately, which is a common practice across the exercise bike market, the ProX’s advanced connectivity earns it a strong 4 out of 5 stars for heart rate monitoring capabilities.
Display and Stat Tracking:
The Assault Bike ProX is equipped with a 5-inch by 8-inch LCD monitor, a standard size for fan bikes, powered by four included AA batteries. This high-resolution display provides clear readouts of key performance metrics, including calories burned, distance covered, heart rate, speed, power output (watts), and revolutions per minute (RPM). Its connectivity with the Assault Fitness App further enhances its data-tracking capabilities. Testers particularly appreciated the inclusion of watts and RPM, metrics that are absent on the monitor of the Rogue Echo Bike, offering a more comprehensive measure of power output and training intensity. This advanced data tracking distinguishes the ProX and contributes to its perfect 5 out of 5 stars rating for display and stat tracking.
Conveniences:
The Assault Bike ProX boasts several user-centric conveniences. Its battery-powered operation eliminates the need for an electrical outlet, offering unparalleled placement flexibility indoors or outdoors and removing potential tripping hazards in commercial gym settings. The integrated device holder and water bottle holder are practical additions that keep essential items within reach during workouts. While comparable conveniences are found on some competitors like the Titan Fan Bike, others, such as the Rogue Echo Bike, require separate purchases for these accessories. The inclusion of these features as standard enhances the overall user experience. A minor drawback noted by testers is the absence of a built-in wind guard, which would mitigate the direct blast of air during intense sessions, particularly in cooler environments. This accessory is available separately for an additional $39. Despite this, the ProX garners a 4 out of 5 stars rating for conveniences.
Workout Apps and Subscription Options:
The Assault Bike ProX integrates with the Assault Fitness App, a feature lauded by product testers. This free application, available on the App Store and Google Play, offers a wide array of instructor-led workouts and virtual competition options. The app’s ability to incorporate other training modalities, such as dumbbells and kettlebells, provides users with well-rounded programming. However, a notable limitation is the app’s current unavailability on the most recent Android versions, which may restrict access for users with newer devices. Consequently, the app receives a rating of 4 out of 5 stars.
Bluetooth Connectivity:
The Assault Bike ProX’s Bluetooth connectivity is a standard but valuable feature, particularly when considering its inclusion alongside other advanced cardio machines. While not revolutionary, its presence distinguishes the ProX from less technologically equipped alternatives, including Assault Fitness’s own classic model. This seamless wireless connectivity enhances the user experience by enabling data synchronization and integration with other fitness devices. The ProX achieves a perfect 5 out of 5 stars for Bluetooth connectivity.
Noise Level:
Thanks to its belt-driven system, the Assault Bike ProX operates with significantly less noise compared to chain-driven fan bikes like the Schwinn Airdyne. The smoother mechanical action contributes to a more peaceful workout environment, which is especially beneficial for home gyms where noise can be a concern for other household members or neighbors. While the airflow through the fan wheel will always generate some sound, the ProX offers a quieter experience overall. It is rated 4 out of 5 stars for noise level.
Portability:
The Assault Bike ProX is equipped with transport wheels at its base, allowing for relatively easy relocation by tilting the unit and rolling it. However, its substantial weight of 125 pounds can present a challenge for some users when moving it across different areas of a gym or home. Despite this, the inclusion of wheels provides a degree of portability that is appreciated. The bike earns a 4 out of 5 stars rating for portability.
Warranty:
Assault Fitness provides a competitive warranty for the ProX, featuring a three-year warranty on non-wear parts and a seven-year warranty on the frame. While the non-wear parts warranty excludes components subject to normal wear and tear, such as the seat and pedals, this is a common exclusion in the industry. The extended frame warranty is particularly noteworthy when compared to competitors; for instance, the Rogue Echo Bike offers a two-year warranty, and the Titan Fan Bike has a one-year warranty. This robust warranty coverage contributes to the ProX’s long-term value and earns it a 5 out of 5 stars rating.
