New to eBikes - where to start?

Hey everyone!

Just joined the forum and super excited to dive into the world of eMTBs! I've been riding traditional mountain bikes for years, mostly on singletrack and some technical trails, but I'm really feeling the pull of an e-assist for those longer climbs and epic adventures. For those of you who made the jump, what was the biggest "aha!" moment or piece of advice you'd give someone looking to buy their first electric mountain bike? I'm eyeing full-suspension models, probably looking at 20-30 mile rides with a good mix of climbing and descending. Any must-have features or things to avoid?
