The aerodynamic situation of a bicycle is so disadvantageous that the easiest way to get a long range e-bike is to simply ride more slowly. People internalize beliefs about energy-range ratios from electric cars, but they don't translate well to bicycles.

The exact same thing applies to electric cars, though -- going slower significantly increases your range.

  • But cars have much larger constants and linear terms in their efficiency equation and they hit peak efficiency at 15 MPH or higher, whereas a bicycle peaks at half that.

It is kind of a shame that recumbent bikes are expensive and bike nerd coded. A recumbent e-bike with an aeroshell would be fantastically efficient and useful in so many situations, but if you tried to buy one today it is going to cost as much as a car and have everybody else sneering at you.
