As most of you know, all computer devices include hardware (electronic components and circuit boards) and computer code (the software/firmware that controls the electronics and processes the data). While we have typically referred to the iBike's internal code as Firmware, we believe that Operating System is a better-understood term.
What is being introduced today in OS2 is the first revision of the iBike's original "Physics Engine" (the code that converts iBike sensor signals into cycling measurements including Power, Wind Speed, Hill Slope, and more). The original Physics Engine was written in 2005--an eon ago in computer technology time!
OS2 includes a complete re-write of the iBike Physics Engine, resulting in these major improvements:
1) iBike sensor data is processed 50% faster in the iBike's microprocessor
2) Sensor resolution is increased, resulting in higher measurement sensitivity
3) Wind speed measurement accuracy is significantly improved
4) Power measurements are more accurate, consistent, and significantly smoother, even when filtering is not applied
5) Short-interval power efforts (15 seconds or less) are more accurately measured and recorded in the ride file
6) Snapshot CdA and Continuous CdA measurements (requires Newton+) are more accurate and consistent
7) The second-to-second correlation factor R**2 between DFPM and OS2 ride files is comparable to DFPM/DFPM R**2 (i.e. two DFPMs installed on the same bike). In short, second-to-second iBike power measurements are much closer to those measured by DFPMs.
Once you have installed OS2, you'll see it listed in your Setup screen. You won't need to do any new calibrations; you'll just find that your Newton works better... :
We are really, really excited about the performance of the iBike Newton with OS2, and we hope you share our enthusiasm!
And to answer one question that some of you will likely have: we won't be more specific about how we did it. It is our secret sauce
OS2 is a free upgrade for all iBike Newton products and is available immediately through Isaac software.
Please note that OS2 is not available for iBike Gen I/II/III models.
