Electricity Generating Bicycle

[Treedubz]

I am currently attempting to create a system for a bicycle that generates electricity, and I got stumped when I couldn't find a 24v lead acid battery.  I was wondering if I could spin a 24v motor to power a 12v lead acid battery.  Please only respond if you know what you are talking about, and thanks in advance.

just connect 2 12v batters in series

you can spin any motor at any voltage, its the controller that you gotta worry about.

I run a 1500W motor at 48V and 30A (or more, I got it peaked out at 2200W), or 36V 41A, or 24V or 12V or 1V

but its my controller that cuts off the juice.

will this bicycle just be for a proof of concept or do you intend to actually generate power with this?

 

If you want this to create power you will be greatly disappointed by how little a human can actually generate.

Even if you are well trained you will not be able to generate more than a constant 250W over an hour so one hour of heavy cycling is not enough to power an average computer for the same duration, not to mentioned the conversion losses you will have additionally.

Golf cart batteries are often 24v.
