Welcome to the forum.
Well the nice thing about electric vehicles in general is you can learn as much as you want, or nothing at all. We all tout the benefit of EV's being easier to maintain since there are no oil changes or engines, but at the same time a lot of us love to get into the weeds. Just know that initially, you can simply charge the motorcycle and go. Your next step would probably be some light customization, like storage or comfort upgrades. When things go haywire, you have support on this forum and hopefully a good dealer.
Which Zero did you buy? Do you have an previous motorcycle experience?
The most important thing to know is the lithium battery in the motorcycle is not all that different than a laptop computer or cell phone, just much bigger. Regardless of who makes the lithium battery, they like to be kept charged in the middle of the range. That doesn't mean you can't charge it to 100% before a trip - definitely do that - but you also don't want to let it sit under 20% for too long either. (This is true of laptops and cell phones too, if extending the longevity of your battery is a priority)
