No worries Trey
...I've never built an e-bike...
Don't sweat it even a little bit as building a hub ebike is literally no more complicated then swappin' out any bicycle's rear wheel and adding a rack & handgrip/throttle...
...and yer done lol
I've actually had a couple few offers, folks that like my ebike & want me to build them one - but I balk at the idea every time as I'm not a businessman, I'm more interested in just riding then customer service & such shenanigans. So each & every time I ask them the honest question, "Can you change a wheel to fix a flat?" as if they can, they can build their own ebike & if they can't... well, should they really have an ebike yet? Shouldn't they learn that first & then wouldn't the other follow?
Weirdly, interest then seems to evaporate despite my ready offer to help for free - which ofc makes me wonder if they were all that likely to pay up in full or see even such a minor project to completion *shrug* but you've also a different customer base, college kids with disposable income that don't wanna get their hands dirty - I can see the attraction.
In any case, the only two "tricky" bits I've ever encountered with hub motor ebikes is axle thickness & width. You
might need to file the dropouts to fit snug & flush with the oversized, flat-sided axle & it just might be a bit too wide to fit without spreading the stays a touch... but these are simple & easy tasks too, stay spreading is well covered on the forum if it's needful
