The TMM technology originally was developed for the application on electric bicycles. The sensitivity and accuracy of the TMM sensors is however high enough for power measurement.

IDbike already has equipped several bicycles with a TMM sensor to measure power. Also a display has been developed on which the following information can be shown: 

 

 1. Crank Torque
 2. Crank speed
 3. Crank power
 4. Hearth rate frequency
 5. Bicycle speed
 6. Time and Training time
 7. Average values
 8. Total distance, energy and calories
 9. Left/right leg power comparison
 10. 2 Graphs for Torque/Power/HF/Crank speed

The display has a USB connection to transfer the measured information to a PC. There the signals can be viewed and evaluated. Also a real time display is possible, for instance to evaluate the left/right power distribution and "roundness" of pedalling.

Prototype bicycles that have been equipped with the IDbike power measurement system are:

  1. Several Mountainbikes
  2. BMX bicycles for the Dutch Olympic team
  3. A trial bike to evaluate the torques at trail biking
