I’ve read that unless the person riding the bike is vegetarian, the ebike actually has a lower carbon footprint than the normal bike. They’re still both far better than the car (ice or EV).
I’m not sure I understand what you’re trying to say. Do you think you get energy from some source other than food?
If I burn 100 kilocalories pedaling a bike, my body will be using 100 kcal of energy that I got from food. There is a certain amount of carbon dioxide emission associated with the production of 100 kcal of food. That amount varies with what type of food I eat and what farming practices are used. If I choose to simply not eat extra food to replace the energy I used, my body will simply have less stored energy afterwards. My energy absolutely comes 100%, 1:1 from the food I eat, and that food has an environmental impact.
Now, if I ride an ebike, my body will use less energy. I will use energy generated by the power plant. The energy created at the power plant may actually have less environmental impact than the farm creating the food I would have eaten.
Maybe your basal metabolic rate will change because you bike more.
Since you’d have to bike like 30 miles a day for calories from biking to surpass calories from basal metabolism, small changes is basal metabolism will mater a lot
I’m still having a hard time understanding your point. Sure, becoming more fit and replacing fat with muscle may slightly increase your basal metabolic rate but I feel like were onto “I don’t use plastic straws” levels of insignificance.
If you’re biking a few miles to work each day and this ends up being such vigorous exercise that you increase your basic metabolic rate by 50 calories a day or so, you’re still using nowhere near the amount of energy and creating far less pollution than would have been required to drive to work. Small changes in basal metabolism will mean very little.

I might dispute the idea that there’s a 1:1 relationship between marginal calories expended exercising and marginal calories eaten.
A UK study showed ebikes have a smaller carbon footprint due to how much meat British people eat.
