best electric bike motor image
Q. I want to convert my current bike to an electric bike for less than $200. I'm really not that handy with electronics, but if some instruction to put A into B I can do it, I just wouldn't be able to figure out that A goes into B with out the instructions. Anyways, does anyone have some tips? All the sites that I've found are very unprofessional or non-specific so it's really hard to figure out anything from them. I would be willing to buy a kit.
Answer
An electric bike has to have a motor, controller, throttle, and battery pack.
Hub motors are the easiest to install.
overview:
You remove your old front wheel, put the new wheel where the old one was, align the wheel in the slots, adjust the brakes, secure the controller and the battery pack on the rear rack, put the throttle on the handle bars, route the wires safely and tie-wrap, connect the connectors together, turn every thing on and test.
To be of much use, you have to have at least 250watts, and hopefully more.
Largo scooters has a decent kit (go Hub)for $600 and is nice. Every once in a while you can find a WE or BD36 for maybe $350.
A Largo kit has keyed connectors so you cannot hook it up wrong.

Can an electric motor take different voltages?
SILVRSWT
I am interested in buying an electric bike that has 2 batteries that opperate at 12v @ 10 amp hours. They are designed to work together to deliver 24v to a 450 watt (peak) motor at the front wheel. Unfortunately these are heavy SLA batteries, and I would like to replace them with state of the art Nanophosphate Litihium Ion batteries.
Now the kicker: I can only find 36v versions for use in DeWalt power tools (though they are very energy dense).
So what I am wondering is if I can buy 2 / 4 of these and wire them to deliver no more than 36v continuous to the 24v motor and will it improve performance or just burn up the components.
Also as an added question, if it is not possible to run 36 volts directly is there a controller that could accomplish this.
Thanks!
The motor is from Currie Technologies, specialists in electric bikes.
I should add that the motor is DC as will be the current delivered to it.
Answer
Just replacing the 24V pair of batteries with a 36V group will very likely cause something to fail. It is possible that a controller could be designed to allow a 36V group of batteries to work with the motor, but it isn't something that you are likely to be able to easily find and mate up to the existing motor.
Additional information:
If you get a 36V PWM controller and set the current limit to the maximum continuous rating of the motor, that might keep you out of trouble. If the motor has a higher short-time current rating that you want to utilize, that might be difficult to set up.

It looks to me like Currie Technologies offers some models with a 3X12V 36V battery package, 36V controller and 450W motor.
