The electric bodaboda
https://yubabikes.com/cargobikestore/electric-boda-boda fits people down to 57" tall. I have very short legs, 28" inseam, and mine left fits me fine. Be sure to specify drop frame, the other one is for taller people.
There are some non cargo bikes out there for short people; I think juiced goes down to 17" frame, which is the distance handlebar stem to seat post. Look at stepover height spec in court's reviews. I think premium trek has a selection of frame sizes, too.
If you don't like turquoise or white, the 2 colors bodaboda is sold in this year, painting a new bike is not much of a problem. I touch mine up where I've dinged it frequently with krylon spray which comes with built in primer now. Put plastic bags over parts you don't want painted, or cover with masking tape. Tie bags on with vegetable (kale) ties.
You'll find bike shops will not stock frames for short people. You have to pay up front and you're stuck with it if it comes in and you don't like it. Still, having a bike shop cover the warrenty for you is important, as electric bikes occasionally come with electrical bugs that are difficult to diagnose. Santa Cruz is in the center of the e-bike world, and LA & SF are the heartland. I have a selection of one brand here in flyover country, or I could drive 165 miles to Chicago, if I had a car.
