Sorry if this has already been discussed. I have a dc motor generator that produces 12v at 150 rpm. I'm hoping to mate this to an Etek style brushed motor that produces 8hp at 48v. This would be in a small lightweight trike for personal transportation. I would set it up almost recumbent bike style except the pedals would turn the generator at about 8 to 1 or 10 to 1 ratio. That would send power to the motor which would then turn the rear wheel. My question is would this generator motor be capable of handling the load placed on it? Would a blocking diode make any difference on this load? If not, I am prepared to accept plan B. Which is to insert four 12v batteries and use the pedal powered generator to simply charge them as I go. I would use some sort of slider throttle on the batteries for speed control. Sorry I don't have all the tech specs but would this work? It's not free energy if I'm pedaling.
