it seems like a way to make things unnecessarily difficult for yourself.
IA’s response mostly covered it (IME)
I like the light + sturdy non-nonsense simple/pure feel of the singlespeed bike. And I like walking/pushing when have reached my pedal-limit. And being properly out of breath like a kid pedalling my first bike (it was a singlespeed).
At first you ride in fits and starts. Go to limit – catch breath – go to limit. Then the re-learning to ride begins to happen.
And the swinging/hanging like an ape from the bars on climbs, while gurning. You become more aware of your arms and torso so it becomes something like a meditative full-body workout on extended rides.
I live in rolling hilly country. ymmv
Most of all because I find it fun. Making things necessarily difficult for myself. Like swimming. I could hardly swim ten years ago. So going from zero to putting in 45 mins a day at the pool made things ‘necessarily difficult’ for my gasping self. Of course, I could have grabbed a float and flippers…
