Too bad about SRAM ending their IGH production. I've had a hankering for a lightweight folder with SRAM Automatix 2-speed, just for giggles. Something to tote on days when I might need to take the bus or train, or toss the bike into the trunk of a friend's car. I just liked the notion of a bike with fewer cables, maybe just a front brake and rig up the Automatix in hub brake mode.
Tern produced a couple of folders with the Automatix but neither was quite what I had in mind -- a step-through model and a larger Castro with 24" wheels. GT made a version of the 8-Ball with Automatix but it was already discontinued and sold out by the time I heard about it. And I think Xootr offered a Swift model with Automatix, but it was also discontinued.
