Where can I find the bike's serial number?

The serial number of your Charge bike can be found on the Warranty Card that comes hanging from the handlebars of your bike. 

 

The serial number can also be found on a sticker located on the underside of the frame of your bike, in the area between the pedals.  It is 7 characters long and begins with "M" (see detail image below).
