Assault Fitness
Human-powered conditioning equipment built around air-resistance bikes and curved manual treadmills with no drive motor.
What they're known for
A cardio platform where resistance rises directly with athlete output instead of being prescribed by a motor or class screen.
Assault Fitness builds self-powered cardio equipment for home and commercial training. Its AssaultBike family uses a fan and moving handles so resistance increases with pedaling and upper-body effort, while AssaultRunner Classic, Pro, and Elite models use curved motorless belts driven entirely by the runner. The common design idea is mechanical feedback: harder effort creates more resistance or more speed without a programmed motor controlling the session.
