I have a better one: charge from temperature gradients as it moves through new areas.

so, obvious reasons why this cannot work.

Is there anyway to like, siphon off the energy though? Like say, you pedaling produces 600kJ/hr. You have 400kJ/hr going into the bike to produce motion, but then 200kJ/hr goes into a battery. You'd move slower but generate stored potential energy.

I'm not really sure why you would want this, other than the concept of a self-charging electric bike, but on paper it sounds possible?

You would need to output far more than twice the energy that you would get out of it and the effort to pedal would be significantly increased as you would have additional weight to the bike on top of whatever it was drawing.

Taking 1/3 if your pedal power would be like trying to bike through deep mud just to have a small boost later.
