How is the Echelon2(G) console and power upgrade different from the Echelon?
• The Echelon 2 can be easily identified by its black polymer face plate and red body
compared to the Echelon 1’s all-red construction.
• The power sensor has been replaced with a new sensor that is more stable and more accurate than the previous
power sensor, and consumes less energy.
• The new power sensor uses an all new algorithm that provides more accurate and consistent power readings.
• The new power sensor has been simplified by removing the power sensor firmware.
• Now only the console contains the firmware that drives the whole system, and firmware updates for the entire
system can easily be done through the USB drive.
• There is now a dedicated ON/OFF button at the top.
• The END button has been replaced by the AVG/MAX button.
• The term WATTS has been changed to POWER, though the units of power are still measured in watts.
• The speed display has been removed, and the heart rate, calories, and optional gear display have been moved
up to the third line.
• There are now AVG and MAX power displays in the STAGE and TOTAL ride timers so that riders can see their total
ride average power at all times, and they can now see their stage average power.
• The function of the STAGE button has changed so that one press starts a stage, a second press ends the stage
and freezes the data, a third press clears the stage and begins a new stage.
• When a rider stops pedaling and the console enters Pause mode, the timers now will continue running for as
long as the e is in Pause mode; however, the console will not continue counting average power until the rider
begins pedaling again.
• The console connector has been redesigned and now has a protective cap that prevents the connector from
accidentally being unplugged.
• The data file that can be uploaded to a USB drive displays summary data for the entire ride and for each stage,
as well as total ride data.
• Improved battery life.
The Echelon2(G) console seems to report higher or lower power (watts) than the Echelon. Is the Echelon2(G) less accu-
rate than the Echelon?
• The Echelon2(G) has been designed, tested, and validated to be more accurate than the Echelon. In some cases,
the Echelon2(G) may report lower power (watts) than the Echelon due to improved accuracy. If riders are used
to higher numbers and want to see higher numbers, then the PWR ADJUST feature in the service menu can be
used to adjust the power display to be higher (or lower if desired). The PWR ADJUST feature allows you to adjust
the power up or down between -99% and +99% to change the level of power that is displayed for a given level
of resistance.
How does the Echelon2(G) measure power and how does that method of measurement differ from how other group
cycling bikes measure power?
• The Echelon2(G) uses a simple and robust position sensor to measure the angle of the resistance mechanism.
The console then uses an algorithm to calculate the power based on the angle of the resistance mechanism.
The algorithm was developed using a laboratory dynamometer to validate the accuracy of the power algorithm,
achieving a level of accuracy that is comparable to other group cycling power meters.
