This is my current bike:

I'll take it to a local bikeshop here, the one I bought it from is out of business. This other place has been in business over 50 years, maybe they'll be able to fix it's shifting. I'm handy around the house, but when it comes to mechanical stuff, that's a bit out of my wheelhouse.
I think the consensus seems to be use manual bike for now, or buy a ebike that's less expensive.
Smaug1 I have considered a grocery run, the grocery story I go to is only about 4 miles away, but there aren't bike lanes that direction for any of the route, and I'm near a lot of factories so there's a lot of semi travel, that concerns me. If I bought a $4k ebike, I'd probably be too concerned about it being stolen to do a grocery run, though the store does do curb side pickup. One the plus side, the elevation change in that direction is only 100 feet over those 4 miles. Pretty flat.
Something I'll have to keep in mind.
