Spirit Medical Systems Bi-Directional Upright Lower-Body Ergometer - The MU100 Medical Upright Bike by Spirit Fitness is a commercial ergometer cycle designed for use in medical and specialized care applications for muscular and cardiopulmonary rehabilitation and physical therapy. The MU100 addresses lower-body conditioning with advanced options for optimal knee positioning. Clinicians may input desired knee flexion angles and the software will suggest the pedal and the seat’s fore/aft position. Variables such as body symmetry and limb length can be taken into account for clinicians to finely tailor to every patient’s needs.

The MU100 is equipped with the standard MA900 Rehabilitation Adjustable Crank, allowing clinicians to address lower extremity range of motion differences by individual positioning of the pedals.

Spirit Medical Systems Group, the medical division of Spirit Fitness, offers a full series of medical-grade cardio equipment including bi-directional treadmills, recumbent steppers, upright ergometer bikes, and recumbent ergometer bikes. Spirit medical cardio machines offer specialized functionality, ergonomics, programmability, and accessibility designed to meet the needs of both doctors and patients alike. In addition to standard hospital and physical therapy application, Spirit Medical Systems treadmills, steppers, and cycle ergometers are ideally suited for use in Veteran Affairs medical centers (VAMC), university research hospitals, Wounded Warrior care centers, sports rehabilitation centers, neurological clinics, elderly care facilities, and pediatric treatment centers.

Purchase Spirit Fitness Commercial Medical Upright Exercise Bikes on GSA contract - All Spirit Fitness Medical Series cardio equipment can be purchased from Ironcompany on GSA Contract GS-07F-0104M and CMAS Contract 4-12-78-0066A.


  • Adjustable Pedal Cranks: Enables a clinician to adjust the bike to accommodate a patient’s ROM performance capabilities. This includes independently, single side or bi-lateral adjustments from a limited range-of-motion as small as 15 degrees through full range-of motion.
  • Bi-Directional Resistance: Forward and reverse pedaling for instantaneous retro-cycling
  • Multiple Resistance Modes: Constant resistance, constant power and Isokinetic resistance
  • Dynamic Braking: Minimizes impulse loading
  • Work Rate: Range from under 5 watts up to 1,750 watts
  • Documentable Patient Positioning: All seat and pedal crank adjustments have numbered indexing for consistent patient set-up from visit to visit
  • Multiple Seat Adjustments: Up/down seat position detents | Fore/aft patient positioning | Hand-tight, positive locking knobs
  • Intuitive interface for ease of operation
  • Unique knee angle data input: Allows entry of desired ROMs to determine seat and pedal crank settings minimizing the guess work
  • Set-up mode: Allows quick entry of patient data, resistance resolution, settings, and how the information is displayed
  • Large, easy-to-read displays: Time, RPM, Watts, Calories, METs, Heart Rate, Power, and much more
  • Multiple Programs include: Quick Start, Manual Mode, Preset Hill, Plateau, and Interval profiles; Custom Facility protocol program, VO2 sub-max YMCA protocol, Isokinetic speed based resistance (from 25 to 100 RPM)
  • Unique Symmetry program: Measures and displays power around the pedal stroke; Biofeedback encourages patients to maintain power between right and left leg
  • Measurement of Bi-Lateral Power: Example: "Left 41 watts - Right 34 watts"
  • Software Assisted Patient Set-Up
  • Heavy Duty, 8 Groove Poly-V Belt for smooth, quiet operation
  • Dual Spring Loaded Idlers provide a low start-up resistance and forward/reverse pedaling motion
  • Pedal to Brake Ratio provides smoother pedaling motion
  • Electro-Magnetic Resistance: Allows for very small increments of workloads (5 watts per level at 60 RPM, 2 watts per level at 30 RPM
  • Dual Electromagnets: Provides a controlled isokinetic resistance and unique Dynamic Braking mode

Advantages and Clinical Applications:

  • Closed kinetic chain: Begin exercise earlier, safely, and impact free within the pain free ROM thereby reducing the patient’s “fear factor”
  • Patient positioning: Adjustable swivel seat position, seat back, and pedal crank for easy patient set- up, knee and hip angle adjustments
  • Exercise in both directions: Active movement in both directions
  • Bi-lateral symmetry: Monitoring assists in improving limb deficiencies and walking gait
  • For Patients with: Patella femoral conditions, total knee replacements, ACL, MCL, and PCL repairs, other ligamentous repairs, arthritic conditions, tendonitis, and many more conditions will benefit

OPTIONAL Accessories:

  • MA901 Neurological Pedal Set: The MA901 enables patients with neurological dysfunctions to exercise in a closed chain environment. This is achieved by having the patients’ feet secured to the pedal with a heel cup and 2 straps. The MA901 offers the following features:
    • Sold as a set (pair)
    • Available option for MU100 Upright Bike and MR100 Recumbent Bike
    • Increases motor learning and range of motion
    • Promotes strengthening and skill building
    • Adjustable tightness ensures that the feet do not move during closed kinetic chain exercise
    • Can replace most existing 9/16” threaded bike cranks, converting a standard exercise bike into a clinically effective rehabilitation tool
