At what average speed? What does your bike weigh?

I average 8Wh/km on a hilly route with an average speed of 30km/h. This is about 13Wh/mi at about 20mph. The trike weighs 70lbs.

No. We have already gone over this. You end up losing speed and don't know if you are gaining any distance. If you didn't lose the speed, you could have gone farther on your kinetic energy.

Yup. With any unmeasured human involvement in a riding cycle the regen numbers are meaningless.

i generally agree with you, SpecialX. Voltage can be a very poor measure of SoC, but it can also be fairly good. It depends on the batteries and the conditions under which the voltage is measured. ...

Cool. You can also go to a more efficient motor to get range. The motor I use is at least 10% more efficient than an average hub motor.

You put in additional effort to enjoy some additional assist time at the end. Okay. Whatever turns your crank. You just can't call it 15% range extension or 15 extra km for the same overall energy...
