Welcome to the forum!
There are also some people, who for whatever reason, can’t keep a bicycle upright. You’re better off finding out if you can balance on two wheels on something that is slow and light to fast and heavy. (yes, I know at speed the motorcycle keeps itself upright, but try doing a slow race without a natural sense of balance)
We have several bicyclists on the forum; I’m sure that they’ll be more than happy to help you with any questions you might have.
