Dynamic Fluid Fitness M850 UBE Upper Body Ergometer

Upper-body cardio and strength, built to include every body.

The M850 UBE is a dedicated upper-body ergometer with 10 levels of patented fluid resistance and bidirectional operation. The seat is removable, so a wheelchair user can roll up to the same machine a standing user just stepped off — same workout, same metrics, same equipment.

The crank height and grip positions adjust through a wide range, which is why you’ll find this exact machine in rehabilitation clinics, physiotherapy practices, and serious home gyms that don’t want to skip leg-injury weeks.

Patented Variable Fluid Resistance Tank

• 10 adjustable levels with smooth, instant transitions.
• Bidirectional operation — forward and reverse.

Auto-Detect Bluetooth Console

• Auto-detection of resistance level on the Bluetooth console.
