    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.

    Good catch, SpecialX. Watt-hours are cumulative. Although a Watt-Hour is a measure of energy and is the product of Watts X hours rather than Watts per hour.

    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. ...

    I was informed the Bafang crank arms are 170mm. I have purchased Schlumpf crank arms to bring them down to 155mm on a recumbent.

    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.

    I'm not sure what you are really measuring. You should measure Ah or Wh. Use a standard course with and without regen and don't pedal.
