Trifecta (Worksman) three-wheel now a two wheel
My wife went walking and saw a used bike, told me to buy it and I did what husbands do - take orders from their wives.
Turns out the tire and rim and hub need work. Any thoughts as to where to get another rim for this bike? It is a 20 inch wheel, axle is 5/8" in diameter, and it appears to have a key slot on the axle.
Thanks!
P.S. My bicycle experience includes breaking my front teeth falling off a bike racing down a hill in Oakland in 1966, colliding with a milk truck and being knocked unconscious for about an hour in Napa Valley in 1969, and numerous wipeouts in the 70s jumping everything from 10-speeds to Stingrays off homemade ramps in the neighborhood thanks to Evel Knievel. For the younger people, we didn't have helmet laws and back then social networking meant going outside and doing things with a bicycle that defied physics.
Thrilled to have made it to senior citizen... can't wait to show folks the old fogies on the way to the pool what I can do on a three wheel.

From your handle, I gather that you live in South Florida. If so, you're in luck because these trikes are very common there, and you shouldn't have a problem getting parts or service.
Just to get the terminality straight, bicycle wheels conprise 3 elements; hubs, spokes and rims. So, if you're shopping for a rim, all that matters is size and the number of holes. However, you'll then need to lace it to the hub.
OTOH you can shop for a built wheel, but need to get one with the specific hub, which is keyed to the drive axle. Those hubs are specific to trikes, so you'll need to find a source that knows trikes.
Worst case, ANY decent bike shop should be able to source a rim and lace up a wheel on your hub.
Last thought, your wheel may be saveable, so don't write ot off yet.

some close measuring will probably show the axle to be 15mm (.590"), not 5/8"... the typical trike only drives one rear wheel... the wheel that is driven is typically driven by a flanged hub with a pin in it...the pin mates up to any of three holes in the wheel's hub flange
the keyway is for the central drive from the pedals, and is not used for the wheels, typically.
here's one of the flange drive ones... there are also "D" drive styles...

I'm sure these people can help. Even if only telling you the parts that you can then scrounge.
