Maybe. But electric bike adds more weight. More weight is more work on the man. You cant get around that fact. Solar panel instead of a battery MIGHT work but again the panel adds more weight/more work. A iift balloon on top could off set the weigh..... but that adds drag slowing you down if you want to proceed forward which adds more work on the man. And then...... no matter what...... a man has got to pee sooner or later! That would lighten the load a bit .... but did you ever try to take a pee while peddling a bicycle?
