Detailed Description of Ride Metrics
Power
• Power is the energy per second that the rider produces. It is measured in watts just as on outdoor bike power
meters.
• Power can be displayed in up to 4 digits.
• Given the dierences between outdoor and indoor bikes, and dierences in riding conditions, it is common for
a rider to have a dierent power output on an indoor bike than on an outdoor bike.
For use with the Echelon2 sensor type:
• Power is determined by measuring the position of the resistance mechanism, then a highly rened calculates
power.
• Schwinn validated the power accuracy using an in-house, calibrated dynamometer; margin of error is generally
±5%.
• Proper calibration of the power sensor is crucial to achieving a high level of accuracy.
• Magnet gap is set at the factory, but Schwinn recommends checking magnet gap to ensure it is properly set.
• Instructions for checking magnet gap and calibration the power sensor can be found on the Schwinn
Equipment support website at http://support.corehandf.com/637-4458
• Schwinn does not validate the accuracy of the Echelon2 against commercial road bike power meters since all
power meters measure power dierently. Therefore, it is possible that the power reported by the Echelon2 will
not match the power reported by commercial power meters for road bikes.
• Proper calibration of the power sensor is crucial to achieving a high level of accuracy.
• The accuracy of power output and consistency of power between bikes can be adjusted using a feature in the
CALIBRATION menu called POWER ADJUST.
• The POWER ADJUST feature can also be used in cases where a studio wants to match the reported power of the
Echelon2 to any specic outdoor power meter.
For use with the 4iiii sensor type:
• Power is a direct measurement from the 4iii Powermeter via crank strain
• 4iiii validated the power accuracy in-house; margin of error is generally ±1.5%.
• Proper calibration of the powermeter via 4iiii app is crucial to achieving a high level of accuracy.
• If upgrading from Echelon2 sensor type to 4iiii sensor type, you will see a slight reduction of power based on
the improved accuracy of direct strain gauge measurement from the crank that also considers biomechanical
pedaling technique and ineciencies.
RPM
• RPM measures the rotations per minute of the crank arm and is either measured by the RPM sensor if using
Echelon2 sensor type, or transmitted from the 4iii Powermeter
• There is no minimum RPM requirement for starting the ride timer.
Gear
• Expresses level of resistance. The gear number increases as the resistance knob is turned clockwise.
• Gears cover a range of POWER values.
• Gear display can be turned o in the settings menu if desired.
Calories (CAL)
• Calories on the Echelon2 are calculated directly from the power assuming the rider has an average tness level.
Calories are a measure of energy expended while on the bike.
