Boulder, CO: 4iiii Innovations Inc. requested a study to independently test the accuracy of the PRECISION Powermeter technology at the Locomotion Lab. The complete results of the tests have been released in a white paper written by Rodger Kram, Ph.D. and Wouter Hoogkramer, Ph.D., both of the University of Colorado, Boulder and Scott Cooper, P.h.D. of 4iiii Innovations Inc.
These third-party test results prove the accuracy of PRECISION and Podiiiium PRECISION Powermeters.
The tests included multiple PRECISION PRO and Podiiiium Pro PRECISION Powermeters on alloy and carbon cranks being compared to power calculated by a bike treadmill for outputs ranging from 150-350W. Results showed an average error in power reading of 1.58% for PRECISION PRO Powermeters and 0.84% for Podiiiium Pro PRECISION Powermeters on carbon cranks.
Following the results of the test, 4iiii CEO Kip Fyfe issued a challenge to the rest of the cycling power meter industry. “We’d like to establish a new gold standard for testing in the industry,” said Fyfe. “We challenge all of our competitors to have their technology independently tested by the lab in Boulder.”
