MONARK 939

Reliable exercise assessment starts with a workload you can verify and a riding position you can reproduce. The Monark 939 Upright Cycle Ergometer brings both together for rehabilitation clinics, hospitals, occupational health programs and professional testing environments. Its Electronic Pendulum System, EPS, provides electronically controlled resistance with mechanical and electronic calibration, helping clinicians compare performance across sessions with greater confidence.

Two operating modes support different assessment and training goals. Constant power maintains the selected watt output as cadence changes, while constant force maintains the selected resistance in kiloponds. This distinction gives practitioners control over how effort is prescribed and measured. The 20 kg (44.1 lb) flywheel supports consistent pedalling, while the Novo Duo monochrome touchscreen presents cadence, workload and session information clearly.

When equipment is difficult to access or adjust, positioning can take valuable time away from exercise. The 939’s low step-through frame, wide padded saddle and horizontally and vertically adjustable seat and handlebars help accommodate individual needs. For active aging, rehabilitation and adaptive programs, these adjustments support considered positioning, with assistance matched to the user’s transfer ability and balance.

RS232 and USB-B connections support integration with compatible ECG and cardiopulmonary exercise testing systems. Bluetooth Low Energy and ANT+ expand connectivity, allowing the ergometer to serve both standalone sessions and connected assessment programs. For facilities investing in supervised wellness or clinical services, that versatility supports broader use from one station.

Manufactured in Sweden, the 939 combines an anti-corrosion-treated, powder-coated frame with recycled plastic covers. Verifiable calibration and access to service support help protect its long-term usefulness. At Resolution Fitness, I can help review user requirements, system compatibility, placement and ongoing maintenance so your equipment supports the work you need it to do.
