i wanted to make an electric bike but i dont know how to make the chain spin... how does it work?
does electricity and battery make it spin or what how does this all work?
Answer
You are right. An electric motor and battery are what is needed.
But most electric motors are either direct drive in the rear hub OR there is a roller that drives the front wheel directly. With your level of expertise I'd recommend getting a kit. Australia do some good ones.

i am trying to make an electric bike for my granddaughter. can anyone give me some suggestions on how to accomplish this? what size motor would i use? can the battery be recharged while in use? any info would be appreciated.
Answer
To answer your question, 24 to 36V would be more realistic. 12V will be a very slow e-bike (maybe that's what you want?)
That said, this is a classic make-vs-buy proposition. Let me hazard a guess that you want this by Christmas, and it needs to work, right?
I suggest buy.
The reason is, motors for e-bikes are much more robust than those you might find in a hand tool, kid's ride-on toy or a starter. A typical e-bike motor will be 500W or more sustained duty, and so will have the extra mass and cooling to handle it. A tool or starter motor just isn't built for that kind of duty and will fail in short order.
Plus, the kit will come with a speed control - and if done right the controller will do regenerative charging too.
Lucky for you, there's lots of e-bike kits, both the in-hub style and chain drive. Looks like they run about $400, with the bulk of the cost being the motor and battery.
First link below is to a site that sells both parts and complete kits. (Lots more if you google "electric bike kit" - second link is just an example).
BONUS: sub-8 second electric drag bike (last link.) Just because.
