Keep in mind that although an electric bike might use more energy input than a regular road bike, it uses a much cleaner type of fuel. Even the most dirty coal power plant in the world has a significantly lower CO2 output per watt hour than the food you are eating to power a bicycle. Even if you are vegan
A plant based diet has a CO2 intensity of ~1 g / Wh
Yes, and since our metabolism is very inefficient you actually need to eat almost 4 watt hours worth of food for 1 watt hour of energy output, everything else just turns into body heat. Meanwhile ebikes have an efficiency of roughly 70-80% when accounting for charging losses and motor efficiency.

We should probably just stop eating.
