Photo screenshot is from http://www.bikecalculator.com/ and uses my data from bike and rider as if no electric assist, so we can discover the power contribution from electric.

466 - 271 = 195 Watts of electric assist.

If 466 calculated per bikeperformance.com screenshot and excluding 50lb bike weight then 446 - 235 Watts average = 231 electric assist.

Correction 466 not 446.

If 466 calculated per bikeperformance.com screenshot and including 50lb bike weight then 466 - 253 Watts average = 213 electric assist.

VO2 Max now removed from health data. Was guessed at 39 ml/kg/min, so not known exactly. This now looks like more realistic data. Bike weight is 50 lbs. Rider backpack 15 and rider 215 giving all up weight of 280 lbs.

Rider power output is estimated from calories burned, assuming a 24% efficiency and the all up combined weights above. As a result, the numbers produced are not perfect – however, they are accurate enough to be useful. In addition to the information above, the duration of the ride and rider's average heart rate are used. As a result, a ride must have heart rate data in order for calorie or power data to be available.
