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.
