18" might be a good middle ground? (eg. Birdy; Tyrell IVE)
If not, options for 1.75" or 2" might be a good thing to consider as well.
I am more of a value guy. I ran a bike shop for 30+ years and sold it to my son. I really like my 20" folders. I put Schwalbe 1.1" tires on my Dahon Mu d10. It is certainly much much harsher ride than the 2" tires it came with. The speed difference is significant also---way faster. I live in Montana --the 4th largest state in the US---I doubt any shop in the state has an 18" or 14" tire or tube in stock. But every one of them will have 406 tires and tubes.
I ride in the dark early mornings a lot. I ride my 26" mountain bike converted to an e bike at night with 2.1 smooth tires. I'm worried about bumps I don't see at night.
But as a tire seller I am totally into 406. The variety and price of 451 and the 16" and 18" tires are so limiting. All three of my folders are 406. (Swift, Mu d10, IGH 8 Mu).
