Assault Fitness
Assault Fitness, headquartered in Southern California, has emerged as the gold standard for air-bike training gear. Their AssaultBike line—including the Classic, Elite, and Pro X—features fan-based resistance, robust steel frames, and smooth pivot systems built for intense, everyday use.
Originally inspired by legacy Schwinn Airdyne bikes, the AssaultBike was refined throughout the 2010s with input from CrossFit athletes, making it heavier, more durable, and better suited to interval training. It quickly became a staple at CrossFit Games and elite training centers worldwide.
Despite its reputation as a “misery machine,” the AssaultBike supports both anaerobic and aerobic conditioning. It automatically scales resistance to your effort—ideal for high-intensity sprints as well as steady Zone 2 sessions—with low-impact mechanics friendly to joints.
Popular workouts include Tabata-style intervals, HIIT protocols, and even reverse pedaling drills to engage overlooked muscle groups—all tracked through the bike’s onboard console for metrics like watts, time, RPM, and programs based on calorie, distance, or heart rate goals.
Durability is central: Assault bikes are engineered to withstand rigorous daily use in commercial and home gyms alike, backed by features such as sealed bearings, six-seat adjustments, and easy mobility.
For longevity-focused users, biohackers, or athletes seeking efficiency and resilience, AssaultBike offers unmatched cardio durability, multi-modal training capacity, and validated effectiveness in improving VO₂max, insulin sensitivity, and metabolic conditioning.
