The Dynamic Fluid M850 UBE (Upper Body Ergometer) is a premium, full-commercial-grade arm cycle designed to deliver versatile upper-body training for fitness, rehabilitation, and performance conditioning. Built for both seated and standing use, it provides a smooth, low-impact workout that targets the arms, shoulders, core, and upper torso. At the core of the M850 is Dynamic Fluid Fitness’s patented Twin Tank Variable Fluid Resistance system, offering 10 adjustable resistance levels. This system delivers a consistent, “on-water” feel with resistance that remains smooth at any speed. Users can easily shift from light rehab intensity to high-performance training, with the ability to change resistance and direction (forward and reverse) even during the workout. The M850 is equipped with a Bluetooth-enabled Interactive Performance Monitor (IPM) featuring auto-detect technology. This console tracks key metrics such as time, speed, distance, stroke rate, calories, and watts, while also supporting heart rate monitoring—helping users track progress and optimize training sessions. Designed for maximum adaptability and accessibility, the machine features a fully adjustable ergonomic setup, including customizable crank height, crank length, and handle angle. The contoured seat adjusts smoothly and can be removed entirely, allowing use with a wheelchair, fitness ball, or in a standing position—making it especially suitable for rehabilitation and inclusive training environments. Constructed from high-quality steel and aluminum, the M850 offers a rigid, stable frame built for heavy daily use. Its self-powered design requires no external electricity, allowing flexible placement in any gym or home setting.
