Ebikes + renewable energy is more efficient even than a human riding a traditional bike! The energy has to come from somewhere.
Ebike for short distance and electric train on long distance.
The french TGV can do 312km while enjoying only 1kg of CO2
Why should regular bikes use more energy, given they’re only manufactured once (as are bikes), have no degenerating batteries and don’t need electricity are less efficient than ebikes?
I don’t think this is true. Ebikes are actually not very sustainable: https://solar.lowtechmagazine.com/2023/02/can-we-make-bicycles-sustainable-again/
But if it replaces a car, it is still very nice!
It’s strange that they didn’t include the food offset by the ebike though. This link tries to give a comparison between the two accounting for a typical European diet (which is also far more sustainable than the typical American diet).

I think it is reasonable to ignore food, since it will be more or less equal to the energy you would spend exercising in other ways (jogging, gym, …). Especially when commiting in a city (<10km).
But your link still shows a nice overview when taking that into account specifically!
Yeah, doesn’t quite make sense unless it’s implying that it’s within the average lifespan of the vehicle. Maybe then you can get further on an eBike than you can on an equivalent regular bike before it falls apart?
Doubtful, given that it is much more sustainable replacing cogs and chain wheels only than to also replace the motor…
But you also pedal way less on an eBike. Not sure if it’s enough to offset that though.
How does a bike emit CO2
A person riding a bike has to consume extra food to burn energy in their muscles to propel them. The energy has to come from somewhere. There are CO2 emissions associated with producing food.
@bonkerfield I really need to go back to biking (also just testing if my reply on Mastodon bubbles up there 🚲)
