If you are having a hard time finding a source, it’s probably because there is none. Riding short distances burns very little calories and most calories the body needs are from idle consumption. Which the battery has to solve degree too
Riding a short distance vs riding a long distance is irrelevant. Both systems require an amount of energy per unit of distance. Because the energy is supplied in different ways, there is a different total amount of carbon emitted of per unit of energy. For ebikes, that amount is lower than it is for traditional, human powered bikes.

IIRC cycling is the lowest joule/km form of transport available.
