I wrote this along time ago when I owned both bikes:

I also have a Tikit. I'm not sure why you are scared of it. The wheels are only 2" smaller in diameter (406mm vs 349mm rims, 25.4mm to the inch), the fold is much better, and it rides about the same. You don't pedal faster, the gearing is higher to make up for the smaller wheels.
The Swift Folder basic fold is faster than the NWT and stays together better. The NWT fold is smaller. The Tikit is smaller and faster than either of them, and holds itself together nicely.
I didn't like flying with the Swift Folder, that was my primary reason for selling it. Packing it into a 29" Oyster suitcase takes a long time. I never tried packing it into a F'Lite suitcase, that is probably better.
All are good bikes, you just need to decide your reasons for having a folder.
