Bike Fitting System

TEKFIT PRO is a system specifically designed for bike fitting:

 1. Angle Measurement — Ensures the rider’s posture is comfortable, safe, and optimized for riding efficiency.
 2. Stability Assessment — Evaluates knee joint and pelvic stability during cycling, providing targeted solutions for improvement.

Through real-time visual graphs, TEKFIT PRO helps you easily adjust your bike shoe cleats and frame settings while recording each adjustment's outcome for later review. This system features fast analysis speed and accurately interprets 3D joint dynamics, surpassing traditional 2D technologies by simultaneously measuring multiple joints, offering more comprehensive analysis.Additionally, this system offers an outdoor assessment mode, removing the limitation of only using indoor trainers. It allows for real-world evaluation of stability and performance on actual riding routes.

TEKFIT PRO Dynamic Joint Angle Measurement

Wear seven sensors on the wrist, elbow, shoulder, hip, knee, ankle, and toe to measure the following angles:


  • Elbow Angle
  • Arm Angle
  • Hip Angle
  • Knee Angle
  • Ankle Angle

TEKFIT PRO can instantly quantify angles and record historical data for continuous optimization, helping every rider find their most comfortable and efficient riding posture.

Usage Process

Real-time Motion Assessment Display

  • Real-time motion trajectory of left leg / right leg / pelvic.
  • Display the real-time angle of outward and inward.
  • The maximum varus / valgus rotation angle.
  • The maximum rightward / leftward rotation angle of pelvic.

Report

  • Motion trajectory of left leg / right leg / pelvic.
  • Stability of left leg / right leg / pelvic.
  • Angle of pelvic rotation.
  • Lateral or medial angle of leg rotation.
  • Power balance of left and right legs.
