A friend of mine who is an avid bicyclist had to quit due to multiple
injuries. As a move perhaps of desperation, he bought a pedal forward
RANS bike frame and built it up with high grade components.
This is pretty much what it looks like:

I tried it and found it to be extremely pleasant to ride. I think people
starting out riding would prefer this greatly over any conventional bike
including those 'comfort' bikes.
What I enjoyed was the seat as opposed to a saddle. He put a seat
similar to a recumbent seat which you sit on rather than straddle.
I liked the up high like a bicycle (as opposed to a 'bent) sight line
but also the upright posture which means I was looking at traffic and
the scenery without having to crane my neck up.
I also enjoyed that I just got on the bike with my full street clothes -
even hiking boots - and the ride felt natural. It struck me as a highly
practical form of transport because you don't need to be specially
clothed to use it.
I'm unsure if I'll get one, but I was very impressed. I suppose a
conventional bike like a 'racer' type would go faster, but this thing
seems to have it made for comfort and practicality.
BTW, my friend was in the middle of a casual 70 + mile ride when I
interrupted him for a demo ride. It's not like you are restricted in
range by the unusual configuration.
I'm impressed.
