Business across the street tossed this to the curb last night:
Seems to be a Vivi MT20: https://viviebikes.com/products/vivi-mt20-step-through-folding-electric-cruiser-bike
Front fork is tweaked hard:
No key, missing front wheel. Battery is in in but without the key you can't remove it. Trying to decide if I try and fix it, or strip it for parts to use on a future project.
Nice score! FWIW, the battery lock may be surprisingly easy to pick.
If it were me, ride on electrically propelled cooler.

Mucked about with it a little more last night. I'll try picking the lock before I drill it. The battery charging port looks a lot like the one for my escooter, so maybe I'll try it. If I can get the bike to power on that makes a big difference in how I proceed. If it won't power up, I'll just part it out.
If it was a mid-mount motor I'd have already yanked it apart and started working on mounting to a go kart frame.
Ebay air fork for $100 and ride it?

It's alive!!!!
Today I pried the battery off it and hotwired the ignition switch. The motor still works!!!
Now to un-pretzel the front fork...somehow.

Back in business!! I took two floor jack handles, shoved them in the forks, and made a wish. It isn't perfectly straight but it works. I snagged a 20" wheel from a surplus BMX bike and took a test ride. It works! It has a throttle like a motorcycle, or you just pedal and it assists. No idea what ot do with it now.
I wouldn't trust those forks now that you've bent them back. Way cheaper to pay for a new fork than for dental work.

In reply to the_machina :
True. I'll keep an eye out for a parts bike. I need a proper front wheel too. The BMX wheel doesn't have provisions for a brake disc, and this thing needs all the braking it can get.
Google the following:

I've now put maybe 30 miles on the bike and I have to say I'm really enjoying it. I tweaked the back brakes to have almost no slack, to the point I can lock it up (but don't). I blew out the rear tube so it now has a heavy-duty tube in it. Took it to the beach and used it like a second car. My family went to the beach in the car in the morning, I stayed at the house to work until noon. then I biked to the beach to meet up with them. Worked great.
Current plan is to keep an eye out for a used front wheel and buy a new fork once I research the specs. Otherwise it has been a solid little bike.
