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.

Real-time feedback
Real-time feedback

Real-time feedback

The pedal forces are shown live in real time. The rider looks at the monitor whilst he pedals and sees two circles in front of him. These are his pedal forces, depicted in circular form – his pedal stroke, in other words. Any changes in the stroke are displayed immediately. This is the perfect basis for feedback training. The all-round pedal stroke is no longer a myth.



The Smartfit Powerforce is simply mounted between crank and pedal: unscrew pedal, screw sensor into crank and adjust, screw pedal into sensor. Every athlete can ride on his own crank system and pedals. The pedalforce system may be used both on a normal bike and on an ergometer.

Analysis and report
Analysis and report

Analysis and report

The data are analysed automatically while the measuring process is still going on. The average value over several crankshaft revolutions is calculated for all force components and displayed along with the crank angle. You can compare various situations and different riders or do pre-post comparisons. The printed plot is available five seconds after the measurement.

  • 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.“
