looks like he's SOL. heres the oregon law
"Are scooters, mopeds, electric assisted bicycles and personal mobility devices legal on Oregon public roads?
Some of these vehicles are legal in some situations if they meet the specific definitions and restrictions in Oregon law. Also, riders must be at least 16 years old and not have driving privileges suspended or revoked.
Although a driver license is not required for motor-assisted scooters, electric assisted bicycles and personal mobility devices, riders must be at least 16 years old (ORS 807.020 and 814.512) and be eligible for driving privileges.
It is also possible for a person whose driving privileges are suspended or revoked to be charged with operating any motorized vehicle while suspended/revoked - including a motor-assisted scooter - on public roads.
Driving any motor vehicle on a public road while suspended is a Class A violation with a maximum fine of $720."
