BB Generator - Chainless?

Hey all
First time poster, long time lurker.
Seems strange posting this as my first post, but it just kinda peaked my interest and I wanted to submit something before I forgot.

I saw a video the other day of a guy who hooked up his front hub motor directly to his rear hub motor, (reversing polarities?) so when he spins the front tire, the back tire auto-spins. My background is in software and mechanical and I am not a super electrical guy so bare with me...

Does charge from a generator correlate directly with the RPM's going into it?
My idea (more of a thought experiment until I can physically experiment) is to run the cranks off a generator mounted at the bottom bracket... instead of driving a chain to the rear wheel, the generator would send direct power to the rear hub motor.
Would peddling a generator even produce enough power and torque to essentially remove the chain drive completely from the bike? This would obviously still be a highly peddle-power bike with no throttle...and as a mechanical minded person, my brain is telling me "less mechanical wear = more electrical problems", but I was curious as to the feasibility of removing the bike chain.

Thanks
...now maybe I should start writing up some actual junk about my bike for my second post

Whoops...can you please move this to appropriate ebike section?

If you want a constant RPM generator, it's easy to make one: Select a motor/generator with an appropriate kv, a rectifier and pedal away.
There are some examples here in the forum, lurke some more... :wink:

And yes, this topic is on the wrong place, perhaps ebike/technical.

A guy here made one a long time ago. the pedals only spun a generator. He said it was fun when he came to a stop at an intersection, and he would lean against a light pole and continue to pedal and put watts back into the battery pack while he was at a stop. That being said, the losses between generating watts with your legs, and then those watts being fed to your motor are gpoing to be very large.

Charging your battery from a wall socket provides energy that is measured in pennies per mile. The big cost of an electric bike is amortizing the cost of a $500-$700 battery over 3 years or so (of daily use). If properly sized for the job their given, motors and controllers should last decades, but batteries still wear out.

Because of the losses when putting watts into the battery, and then even more losses when taking watts out of a battery to feed the motor, your most efficient use of leg energy is to pedal-assist along with the motor, so the motor sips watts instead of gulping them.

Also, even if I use my E-bike as an electric scooter...with the pedals being only foot-rests, having no chain means walking home when the inevitable system issue arises.
