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?

Physics's older brother gonna be looking for this guy.

I don't claim to be an engineering student, why is this a bad idea? Wouldn't he just put a "collector" of energy (like a wind turbine) on the wheels?

It could be an OK idea that just wasn't explained right. Maybe he just wants regen braking but with one wheel for charging and the other wheel + separate battery for power at any given time. Energy would come from pedalling and hills. None of that was explained though

Maybe you can join his team!

But I can forgive a non engineering student… its impossible.

I see a lot of people clowning on this guy but is it possible that something like this could come in handy for commutes with elevation changes?

Coast to work and charge the battery, use pedal assist on the way home uphill.

Seems too niche to sell a bike for this, though.

"Electric bikes are the future of transportation"

Buddy have you ever heard of a motorcycle?! 🙄😂

"Doing research on efficiency and energy conservation"

I refuse to believe that you know energy conservation, because anyone who does know, knows that for a system to be conserved you must take into account all mechanical forces for that system, and that isn't even taking into account resistance of the wire, and current being lost by heat through induction. But carry on with your idea.

or get a better battery since ur saving a lot of weight by not doing any of this. My research idea is not doing his.

It's almost like, it regenerates its energy
