What about the e-bike, how many MJ goes to electricity and how many to human power?
(Also for the human-powered case, biking often displaces some other exercise. And of course using gas is bringing about the climate catastrophe so it's unethical, money isn't everything)
Replying to myself, apparently a 25 km/h ebike does about 4.25 Wh/km of battery power which would be 0.15 MJ of electricity for 10 km. A bit more considering losses in charger.
