I've ridden a fair few electric two-wheelers in my time. Some might be classed as mopeds; some are true motorcycles, and others are definitely e-bikes.
And while I might have individual features/bugs that I like and dislike about each of them, broadly speaking, they're mostly fine—as long as you have realistic expectations, both of what they are and what they can do.
For example, you need to respect the fact that most EV manufacturers are a little, shall we say, optimistic about their range estimates. A smart thing to do is get to know what your average range is for the things that you specifically plan to do on your e-bike or other electric motorbike. Going up and down hills, whether your model offers some level of brake regen, having a spare battery, head or tail winds, and so on are all variables that impact your range. Weight of yourself and any items you might be carrying will also play a role.
