Hello I am wondering if anyone can help me understand something. I read a similar thread on here where someone wanted to setup an alternator on the rear wheel of their e-bike. Everyone was very helpful in explaining the energy losses that would result from that setup. I just wanted to piggy back off of that person's question. What if I rigged the alternator to be connected to the pedal drive chain so that I would be charging the battery via the alternator when I manually pedaled. Im sure It wouldn't give a great deal of energy to the battery to the point of a complete recharge but enough to extend the battery range right?
