Well certainly very late to this party but just got myself a new one of these at a good price and am trawling through all the posts in this thread!

So far this is what I have been trying

1. 130mm adjustable stem riser (I like a really upright ride)
2. New bars also with a 50mm rise.
3. I didn't even try it with the stock Kendra tires and whipped them off to fit Kojaks which is still my favorite tire.
4. Also trying a set of Big Apples

So far I like the ride, its VERY quick. I already own a Moulton TSR and a Brompton and I have to say the Xootr certainly adds to the mix. I would say it rides as well as the TSR though maybe a little more bumpy (the TSR is suspended both ends) though still not bad. Its also half the price. I quite like the fold and in some ways its easier than the TSR "split". will be fine for the car or taking into my office. My Brompton is still my bike of choice when going in and out of shops/restaurants.

I will be back later with some pics once I have had chance to get another (I only have one) big apple 20" tire to fit. I tried the one I had on the back and it does fit though you have to pull the wheel back to the outer stop (mudguard screw) in the rear dropout to clear/stop the tire side rubbing the chain stays.

Finally are these later ones a little heavier, mine was nearer 11kg than 10kg stock ?

Hmm just read this on their website

"Weight. 11.3 kgs (25 lbs.).
Note: this is inherently a very light bike due to the structural efficiency of the TrusFold frame system. We do equip it stock with some rugged 65psi tires and tubes, which actually adds almost 2 lbs (1 kg) to the weight. We also equip the Swift with a generous saddle. If you want to skimp on weight, just put on a lightweight tire/tube set and a racing saddle. "
