Smartfit Powerforce

Pedal force measurement for the scientific study of cycling biomechanics. Delivers real pedal forces in two dimensions, right and left, and with every pedal system.

You can use Smartfit Powerforce to conduct scientific studies, to take a holistic approach to the analysis of mobility problems and to improve pedalling technique by giving feedback during training. With Powerforce the all-round pedal stroke is no longer a myth.

For scientists, sport biomechanicians and professional bike fitters.

Cycling Biomechanics with Smartfit Powerforce

Pedal force measurement

The 2D force sensors record the tangential (Fe) and radial (Fu) pedal force on the right and left side. This enables you to distinguish between propelling force and unused force, to identify pressure, drag and thrust in the pedal pattern and to illustrate side differences. The resulting force vector shows how the rider treads the pedals.



Die Pedalkräfte werden live in Echtzeit gezeigt. Während der Fahrer pedaliert, schaut er auf den Monitor und sieht zwei Kreise vor sich. Das sind seine Pedalkräfte, dargestellt in Kreisform – so wie man tritt. Veränderungen im Tritt werden sofort angezeigt. Dies ist die perfekte Grundlage für Feedbacktraining. Der runde Tritt ist kein Mythos mehr.



Zur Montage wird das Smartfit Powerforce einfach zwischen Kurbel und Pedal eingeschraubt: Pedal abschrauben, Sensor in Kurbel einschrauben und justieren, Pedal in Sensor einschrauben. Jeder Athlet kann sein eigenes Kurbelsystem und seine Pedale fahren. Das Pedalkraftsystem ist sowohl am normalen Rad als auch am Ergometer nutzbar.

Analyse & Report

Die Auswertung der Daten erfolgt automatisiert noch während der Messung. Der Mittelwert über mehrere Kurbelumdrehungen wird für alle Kraftkomponenten berechnet und inklusive Kurbelwinkel ausgegeben. Vergleichen Sie verschiedene Situationen, unterschiedliche Fahrer oder Prä-Post. Der gedruckte Plot liegt 5 Sekunden nach der Messung vor.

  • Neil Martin, cycleright.cc

    „We knew the Smartfit system would enable us to sell more bike’s and that our customers would benefit from bikes that fitted them properly. What we did not expect was the demand we had to fit customers existing bikes. The success that we have had with the Smartfit system has been phenomonal, with lots of happy customers.“
