How much did your lunch cost? How much fossil fuel was burned farming and transporting the food you ate? You probably got around seven hundred calories out of it, which you could easily burn going twenty miles on a pedal bike. An electric bike will burn around 400Wh to go the same distance. Where I live, that much electricity costs less than three cents. Of course, there are side benefits to using food as fuel, like getting your exercise and the pleasure of eating. But I think you've got to stretch pretty far to call it more efficient than an ebike.mi7d1 said:A pedal bike is much more efficient than an ebike.

Edit: On a related note, Justin at ebikes.ca (which seems to be down right now...?) wrote a paper on the subject:

Only the consumables of both transportation modes will be considered in the
comparison. Electric bikes have the same components of an ordinary bike, with
the addition of a motor, motor controller, battery pack, and battery charger. They
therefore have a larger up-front cost to produce. However the electric motor,
controller, and charger, are all maintenance-free with an indefinite life-span, so
beyond their initial manufacture there is little associated environmental cost. The
one component that does require replacing is the battery pack and this will be
included in all calculations.
This treatment is also ignoring all secondary effects. For instance, the health
benefits and costs of exercise will not be addressed, nor will the disposal of toxic
materials in batteries be considered. Accounting for the former would be a
complex task, while the later is less of an issue as battery recycling becomes
more commonplace.
