Motion Analysis
The bikefitting.com Motion Analysis provides a very precise picture of the biomechanical aspects of cycling. Motion Analysis analyses the motions of the knees, shoulders and pelvis. The motions are analysed in real-time under high loading factors. Two cameras follow the motion of both knees, the shoulders and the pelvis. During this dynamic analysis, any deviations or irregularities in the pattern of movement are quantified very precisely. While cycling, the biomechanical picture changes under the influence of the motion and the loading factor (the applied pressure). Small biomechanical deviations are magnified as a result. For example: a cyclist with a small length difference between both legs can usually sit up straight on the bicycle, but when subjected to a (heavy) load, the pelvis will start moving asymmetrically.
The unique advantage of Motion Analysis is that it makes it possible to immediately visualise the effect of possible modifications and adjustments.

Professional measurement
The Analyser determines the exact proper seat angle of the frame. The correct seat angle follows directly from the ratio of upper and lower leg length and is displayed digitally. The final result is a correct sitting position relative to the crankshaft, leading to optimal power transfer and a stable position on the saddle.

The seat angle measurement can be carried out quickly and easily. It is also closely linked to the practical experience of the cyclist, as the cyclist’s own bicycle is taken as point of departure for the measurement.

Digital Calibrator
The Analyser can digitally calibrate a bicycle with regard to the following settings/adjustments:

• saddle height
• saddle setback
• difference in height of saddle and handlebars
• distance from saddle to handlebars

The Digital Calibrator is built from components used in the machine construction sector, including a precise guidance system. A laser pointer ensures that the measurements are read out very precisely.

The Digital Calibrator only measures and reads out the points of contact between the cyclist and the bicycle. Accordingly, the specific frame geometry does not play a role in making adjustments to the bicycle, unless the geometry deviates so greatly from a correct geometry that a correct adjustment is no longer possible. In such cases, the importance of a correct frame size and geometry becomes very evident.


The screenshot below illustrates the optimum X- and Y-coordinates deduced from the measurement. The Digital Calibrator translates the measurements and applies them to the bicycle.

In addition, the Digital Calibrator can copy the exact position and geometry of one bicycle to one or more other bicycles.
