Have you ever ridden anything at all that is similar?
If you can balance a bike, you can balance a scooter.
Scooters and mopeds are very easy to learn, they have automatic transmissions and simple controls. They aren't like a motorcycle where you would have to learn to use a clutch, shift, break correctly, etc.
If you are worried you could start out in a parking lot or back street and you'll figure it out in like 10 minutes, they are pretty forgiving.
