One of the coolest things about riding a folder of any kind is the responses you get from people who think that they are; slow, only suitable for sidewalks, twitchy, incapable of handling any distances, or rough riding.
My P20 is fast, smooth, and I have built it up to use as a separable touring bike... it took me 5000 km last year and has seen further modifications.
Quite a few of my friends have folders and have taken my P20 out for a spin and come back saying that it is as stable a bike they have ever ridden and really bleeping fast.
I have yet to restore the fenders and build new racks and even with that extra weight and my touring kit the little bike just buzzes down the road at good speed.
