Hi,
I’m in a similar situation. I’ve never driven a bike before but I do know how to drive stick. I would suggest that you learn stick if you have a friend who has stickshift car. At least so you know how the clutch works and get a better understanding of the system. I would recommend also that you sign up for the MSF course. I signed up for mine but its not until september 
I wouldnt sell my car for a bike. You never know when you’ll find you need to go somewhere and its raining…
You can still ride I guess but its just that more dangerous.
Just my .02c, take it for what its worth since I’ve never been on a bike and I’m just starting. Been doing lots of research though 
This site helps alot.
