Is it true that I will need one quarter HP plus whatever is lost into the gears to generate 1875 watts? Or is that a matter of speed etc. I saw a device that will spin a no load wheel fast enough to generate electricity, but I think once they put a load on it would come to a stop, All I want to do is maintain Â¼ HP pedaling a two stage increase in speed. What wattage can I expect? And is it true that I could get a higher output than a car generator (running at the same low rpm), with a bicycle wheel rigged as a generator with 36 magnets and coils?
