I do not believe there is a 50cc only license test, any scooter with a petrol powered engine requires a license. Not sure about now, but when I did my scooter tests electric scooters didnt require a license, but since the Gogoro craze i would not be surprised if they now require a license.
Scooter license - petrol scooters
Car license - … cars!
Motorcycle license = bikes over 600cc? i think it was, requires both a car and scooter license.
Then there is light truck, heavy ect…
Scooter license is doable in a day, computer test and practical. Prac is simple as pie, ride straight line, stop, use indicators, do a semi circle and stop before a line after reaching speed.
Car requires computer test, then 30 days of practice, thats every day, for 30 days. Then prac test.
