Where will the serial number be located on the Pride Mobility GoGo Folding scooter?

While the serial number for most Pride GoGo scooters can be found wrapped around the seat post of the scooter, the S19, Pride GoGo folding scooter does not have a seat post. 

The serial number will be on one of the 'X' supports for the seat or near the floor mat on the scooter.
