"...Maybe if I was 170-180lbs, I might have enjoyed it more. It always felt fragile to me thought I never busted anything but spokes. I thought that once the spokes bedded in that issue would go away. For me it never did. The Pantour hub on my never provided me any benefit and I had to watch the brake adjustment so that under full compression they pads wouldn't hit the tires.

If you want a really fast folder and you aren't big, this might be a good option." -Wavshrdr

I don't think your weight played any part in your old bike's perfomance, Wavshrdr. I am far more lighter and smaller than you are and also test rode a similar model to yours during the last Southern California Bike Expo a couple of years ago. The bike suffered a flat tire even over perfect riding conditions as an indoor test rink could provide. I think that the bike must be able to be to fully ride before it's abilty to be fast could be appreciated.
