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?

Do most e-bikes not charge from the pedals? Combine that with regenerative coasting/braking, and this isn't really that dumb. Like yeah, obviously thermodynamics, but an E-bike with pedal charging isn't a closed system.

"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.

It's almost like, it regenerates its energy

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.

No.

An alternator draws energy from the engine spinning but the draw uses more energy than the alternator puts out. It is a conversation system from mechanical to electric power.
