read on another source:"There was an incident reported to me this weekend of a steerer failure on one of the early production bikes. It appears that the lower weld at the base of the steerer failed and the steerer tube separated from the locking body." I think this occurred in Hong Kong.
Helix is (relatively) light, has a nice (relatively) compact fold (the better to allow it to reside in the trunk of my car), and has reasonable sized wheels (the better to be ride over minor potholes. This recent (presumed weld) failure together with limited and (apparently) diminishing tire options is causing me to back away from placing an order for one. It's a shame, as I've sat on the fence for quite a while (primarily while waiting for owner/user reviews).
