It has both a 17-21 fixed cog and freewheel on the flip flop hub. The chainrings are 46x42.

A colleague had a folding Brompton with a similar set up. On a long ride, the chain tensioner fell off and we could not find the pieces. It was ride-able but very frustrating. I don't believe your...

If you want simpler, do a 1x setup rather than what you propose. It just doesn't seem simpler to have to manually change the rear. None of the points you have listed are any real issue. I tour on a...

The idea of a 6 speed Uniglide hub is good. I’d go a bit farther and find a 7 speed Uniglide/Hyperglide freehub body with a thin flange and mount it to a deep flange hub. I’ve done this with a...

Pulley drag is negligible. Use ceramic bearing pulley whells if you are concerned about that, but it doesn't make any difference. IME even most racers don't bother with that.

+1 Front shifting under load is far more problematic than rear shifting. The major negatives I see with your proposal are:

What problem are you trying to solve by ditching the rear derailer? IME rear gear changers work better than front, especially with triples. The added loss from 2 pulley wheels versus 1 is...
