Spirit Fitness MU100 Medical Upright Bike - Rehabilitation & Medical Ergometer

The Spirit Fitness MU100 Upright Bike addresses lower-body conditioning with advanced options for optimal knee positioning. Clinicians are able to input desired knee flexion angles and the software will suggest the pedal and the seat 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 Spirit 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.

Key Features:

  • Adjustable pedal cranks: enable a clinician to adjust the bike to accommodate a patient’s range of motion performance capabilities. This includes independently, single side or bilateral adjustments from a limited range of motion as small as 15 degrees through full range of motion
  • Multiple seat adjustments: up/down seat position detents, fore/aft patient positioning, and hand-tight, positive locking knobs
  • Documentable patient positioning with numbered indexing seat and pedal crank adjustments for consistent patient set-up from visit to visit
  • Bidirectional resistance: with both forward and reverse pedaling for instantaneous retro-cycling
  • Symmetry monitoring to measure bilateral power (example: Left 41 watts - Right 34 watts)
  • Multiple resistance modes: constant resistance, constant power and Isokinetic resistance
  • Work rate range from under 5 watts up to 750 watts
  • Dynamic braking minimizes impulse loading
  • Software assisted patient set-up
  • Sub-max VO2 testing (YMCA protocol)


  • Frame Type: heavy gauge steel welded
  • Power Train (Belt Drive): 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.
  • Braking Device: 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 provide a controlled Isokinetic resistance and our unique dynamic braking mode.
  • Resistance Modes: constant resistance, constant power and isokinetic resistance
  • Resistance Range: 150 Levels (5w, 10w, 15w at 50 Levels Each)
  • Watt Range: 5-750 Watts
  • Bidirectional: Forward and Backward Pedaling
  • Adjustable Cranks: 12 Adjustments (25-158mm)
  • Seat Adjustment: Up/down; fore/aft patient positioning
  • Seat Adjustment User Range: 1290-1970mm
  • Recommended Patient Positioning
  • Symmetry Report & Program: Left Leg vs Right Leg Power; Symmetry Index
  • Multi Function Dot Matrix LED Display: Time and Segment time remaining, RPM, Watts (Left and Right), METs, Symmetry Index, Heart Rate, Calories, Work Level.
  • Power: 100–240 volts AC (standard power supply)
  • Assembled Weight - 181 lbs / 82 kg
  • Assembled Dimensions - 145cm x 58cm x 135cm/ 57 x 23 x 53 in
