The Castro M1 is available via mail order. Around $1000-$1200 depending on model. All stainless steel mono-tubed frame. Available as a kick-back two speed or as an internal 3 speed. Built in Spain. Nice bike - I have had for about a year. Main complaint is the 3 speed version does not handle larger tire sizes due to the front brake. The 2 speed could be modified. Has an interesting sideways turning handlebar to make loading in a car or on a train easier, but the frame does not fold. One size that is pretty versatile for fitting. I am 6'0" and I could easily ride it 4 inches shorter or at least 3 inches taller with the adjustments available on the bike. Available in USA from Gessato.
