@B: (from bottom of the page to which you've linked) "The warranty on the frame, handlepost, and fork may be upgraded to a lifetime warranty if the original owner fills out the online registration. The warranty is activated when the bicycle is tuned and adjusted by a professional mechanic before the owner’s first ride."

For me, all of these folding bikes are going to have issues. I have several of several different mfctrs, like many here. The warranty is important to me knowing that there will be some recourse when this happens. Also likelihood that company will be around in 5 years. Resell value is important as well. A few of the bikes I've bought have appreciated or lost almost no money.
