I recently received my order of a (xootr) swift. Came in about two weeks ago. From the xootr folks the only extra stuff I ordered was one of the bottle cage adapters and the fender kit.
For now I have taken the fenders off. You know how when you fold the bike you shove the seat in all the way and the bottom of the seat post presses against the rear tire and keeps the entire thing folded?
Well, with the fenders installed the bottom of the seat post presses right against the rear fender, and the fenders are not super strong. And so if you don't slide the seat post quite all the way down the thing will tend to unfold a bit if you are not careful and you will still end up with the seat post pressed against the rear fender.
Not a big problem, but I figured that for now I will do w/o fenders. The bike rides great for a folder. My wife clocked me going 27 m/h on the way to work a couple of mornings ago (she was following in the truck).
