I editorialised the title as the original was clickbait, but the video itself is quite good. Interestingly, e-bikes are claimed to have lower emissions than acoustic bikes, although it likely depends on diet (the author didn’t specifically compare a vegan diet between the two types but did indicate that vegan + electric is the most carbon efficient form).
You’re right that the calories burned while riding the E-Bike would also need to be considered. The site you linked gives 220 kcal/hr for “Motor scooter, motorcycle” and 630 kcal/hr for “Bicycling, 12 - 13.9 mph, leisure, moderate effort”. This corresponds to 1960 kcal / 100km excess calories for biking (at 75kg weight). Going slower than that (which I certainly don’t do ;-) ) somewhat reduces the difference. But then the E-Bike is faster and you somehow have to account for that… I’m sure that people have written scientific publications on such considerations. My napkin math certainly doesn’t have that level of rigor.
Overall there’s certainly better ways to reduce your CO2 footprint than switching from a bike to an E-Bike. But perhaps E-Bikes are better than their reputation.
e-bikes have a reputation? Im not claiming they are bad. They are better than any form of transit as far as I know outside of walking and biking. One thing that has not been mentioned is getting excersise is also a general society benefit outside of the strict carbon footprint thing and pollution. Im not sure if public transit could beat it although in my city there is an electric train that does not use batteries so I suppose that might and they are electrifying some busses but the weight makes me wonder if it still could given how light the e-bike is. I keep hoping in the US they will do that tax incentive they abandoned. One thing not related to the article is they tax incentivize electric cars but not bikes but many people simply can’t do an electric car because they can’t plug it in while an e-bike could be brought in the apartment although usually the batter is removable to charge at your desk or whatever.
