"Electric bikes are the future of transportation"
Buddy have you ever heard of a motorcycle?! ππ
"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.

Did not pay much attention in high school
Look out for v2.0 which also features a sail on the front which you blow to go faster.
Okay, but blowing on a sail to go faster is actually a thing. Mythbusters even stated that they did their experiment in the worst method (i.e., not using modern designs and methods), and still found that a fan on a sail could make it move. It's not free energy, but let's not ignore how cool sails are.
This sounded very wrong to me, so I googled and apparently they had a setup where the reflected air from the sail caused a net flow in the opposite direction allowing them to move forwards. But that is less effective than just blowing the air straight backwards without a sail.
When the battery runs out, you pull over and "pedal" to recharge the battery, then you're good to go again!
now that is genius!
I don't own one of these, but that sounds actually useful if for example I'm about to climb a big hill and want to pedal at a less strenuous pace (but for more time) than would be needed to overcome the slope.
Assisted modes already exist, and regenerative braking already exist
But this joke is more funny :)
The traditional method of pedaling uphill less strenuously is to drop to a lower gear. You might go slower, but I'd bet even on existing e-bikes with pedal assist, this is something that's already pretty reasonable now days.
Nice to get a moment to pull out a classic
As someone who sucks at physics, I'm convinced that Trollface has proposed so many solutions around the internet to provide free energy, but the capitalists are conspiring to sabotage him, just as they did to N.Tesla.
This is satire⦠right? I hope it is
Yet another "engineering student" who hasn't learned his Newtonian physics yet. Which I'm pretty sure is covered in grade school, but you never know.
I had this exact idea... when I was 7. That was before I was introduced to newtonian physics.
Looks like it could even be AI style with all the emojis.
Either way, thanks I hate it.
Likely not only drafted with AI, but only pursued because he entered the idea into ChatGPT and asked "is this a good idea?," and uncritically took ChatGPT's enthusiastic support as vindication.
Perpetual motion machine aside, where tf is bro going that the range of an ebike isn't enough, but the speed is
This guy apparently doesnβt understand the first and second laws of thermodynamics. However, in his defense, this is sorta how regenerative braking works, but with less complexity.
Mechanical engineering student huh? Good to know he didn't attend class on day 1 of dynamics
Mechanical engineering student huh?

This is a normal trajectory for college freshmen. Get introduced to a bunch of basic ideas. Spitball and try to see how you can apply them. Start running into all kinds of caveats and engineering hurdles. Go back to class. Bother the RA. Maybe actually learn more about what you're trying to accomplish. Become a better engineer.
Either he's lying about being a mechanical engineer or the barrier to entry to become a mechanical engineer is embarrassingly low.
It this guy seriously proposing a perpetual motion machine for the purposes of EV charging? Also not that it really matters but who the hell has range anxiety on an electric bicycle. You get 30 miles out of those things easily, what sort of bike rides is he doing where you have to recharge that more than once a month?
He should try recharging a solar panel with a light powered by the solar panel. Just achieving infinite power.
Why not cut out the middle man and directly charge battery 2 with battery 1? Switch and repeat.
Newton? Never heard of him.
With this many emojis and em dashes, he's probably engagement farming using llm content, regardless of the thermodynamics gaps in logic
This is dumb as shit ofc, but it gave me an idea that's probably nearly equally dumb as shit:
Regular bicycle, but with an extra gear that can selectively connect to the chain or wheel or w/e, that's connected to a coil torsion spring on a kind of ratchet release.
Basically you flip the switch when it's a good time to rob some energy like when you're on level ground or going down hill. That energy makes you a tad less efficient (but you don't care cuz it's level or downhill), and uses that energy to wind up the coil torsion spring up until a max amount of torque is stored.
Fast forward a bit: now you're approaching an incline, so you flip the switch the other direction and that torsion spring regurgitates that energy back into forward motion, giving you a nice forward burst when going up a hill.
Not free energy by any stretch, but a strategic use of what you're already spending.
Feel free to explain why this is a horrible idea - I'm about as far from a physicist as it gets.
That's effectively what hybrid cars do.
Essentially regenerative braking. Should work, though the question is how coat effective.
Wrong question.
Right question: When the fully torqued spring inevitably fails, who is liable for the deaths of the rider and nearby pedestrians?
F1 has been using this principle for years
It's almost as if one object perpetually moves something that creates a form of motion perpetually to continuously move that first item. Like a continuous motion machine or perpetual movement apparatus. Something like that. I feel like my naming is close, though.
Seems like satire to me. Pretty funny too.
The Law of LinkedIn:
If you think it's satire, it's probably actually just a really stupid individual.
Techbros rediscovering old principles, a tale as old as....well, since the tech industry.
This guy is only telling us part of the truth. You actually need three batteries. The third battery is hooked up to a solar and wind generator. Only then can you achieve true energy independence.
