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?
