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?
What happens to an object in motion when you collect its kinetic energy?
Okay, I admittedly know nothing about this, so bear with my ignorance. Aren’t you just moving gears? It would generally be like an auto engine where you have all of these explosions that push gears. You’re just moving the gear in one direction as a click, click, click.

Turn off the engine of your car, does it keep rolling at the same speed forever?

Where are you going to get that power on a bike? Your legs. Do you really want to peddle away to charge a battery at SIGNIFICANTLY reduced efficiency, then with even more loss of efficiency discharge the battery into an electric motor? Or do you just want your energy going directly to the wheels?

The person in the post is trying to come up with an infinite source of energy which is not possible.

All of these points are well taken, but I didn’t understand it as infinite, but more like to get you where you’re going.
