Somebody has asked me to track down an ITChair for them. It is an aftermarket child set for a Brompton but I am told they are out of production at the moment. http://www.itchair.info/ Does anybody know where a new or second-hand one might be found?
Clever Cycles in portland OR had one in stock when I ordered one a month ago. They may still have them. I did see one on ebay yesterday though but not sure if the person would ship to your location. We really like it.
Since the company that used to make them is no longer making them I am tempted to try my hand at making a second one for when our youngest child gets older. We have 2 bromptons and 2 kids, it only makes sense.
