How about a nice e-Tricycle with a basket on the back?
I'd prefer not to go tumbling to to ground or into traffic if I make a mistake on my bike or someone else makes a mistake and I fall down for it.
That'd be truly entry-level.
For extra wierd, try the diesel Aixam Coupe (https://www.aixam.com/en/licence-free-car-coupe/gti). In the UK these are classified as quadbikes and can be driven by moped-only licensed drivers (aged 16+, normally you need to be 17 to drive).
Unfortunately, the issue with tricycles is the additional space they take up and their reduced maneuverability. They are hard to use on most extant cycle infrastructure, hard to transition to sidewalks or off street paths, hard to park, and quite heavy.
They do enable a people to ride who might not otherwise be able to, but without better infrastructure (protected bike lanes of sufficient width) or slower more forgiving car traffic, they just aren't practical.
