RangeMaker® Attachment
For Limited Knee & Hip Movement Problems
RangeMaker ® is an adjustable bicycle pedal attachment bracket to improve knee range of motion.

This means that when limited knee movement prevents riding a bicycle, the RangeMaker pedal bracket can be adjusted for completing full pedal revolution without pain or stress on the knee joint.

By gradually moving the pedal bracket, improved knee movement can occur in just a few short weeks.

You can go from a 1 inch radius setting



(example of limited knee movement)

 To a 5 inch radius setting



(example of improved knee movement)

RangeMaker ® offers control over both hip and knee range of motion through easy adjustment of the exercise bike's pedal crank radius from 1" to 6.5".

  • A 1 inch pedal crank radius requires only 5° knee bend to pedal the exercise bike.
