Driving an electric bike in Ubud

Hello all!

I'm planning to stay in Ubud long term, but don't have a driving license, and will not be riding a scooter.

Instead, I want to buy an electric bicycle. A couple of questions.

\-Are electric bicycles common there? \-Do you need a license to ride one? (might seem like a silly question since it is a bicycle. But I've heard conflicting things). \-Are they easy to buy in Bali?

Thank you!
