Not a fan of these ultra folders, but thought some of you might be interested. Kaidomain has what looks like a Sinclair A-bike clone for $169 USD shipped. It looks like other countries besides the U.S. can get these shipped free. go to the kaidomain (dot) com site and search for "LDN-002".
I'm not a shill for this company so I didn't want to post a direct link to the product. Make you work for it.
