An automatic two-speed SingleSpeed - oh my!

Yes, I think so. It's this hub...

Cheers, @Delftse Post . It's a centrifugal clutch so maybe it's the same one - I didn't see the make. But it looks like you don't buy a bike with 2-speed, you buy a 2-speed hub for €76 and go on a short wheel building course. Don't like it and you put the old one back on but you've still acquired a new skill.

When I was at the SPIN London exhibition on Saturday with @dktd @deptfordmarmoset @Mice (and others no doubt) I was quite taken by what at first looked like a SingleSpeed that did in fact have two gears. The idea (and practise) being that you start off in a nice easy gear and once you breach 9mph the hub 'auto-changes' into a higher gear.

I gave it a whirl and was really impressed. Am I being a total bumpkin for being so impressed by this? This potentially solves the problem of having to have my SS so highly geared.

I've written about it a bit on my bike blog...

And it's a fixed gear? If so, I'd like to try that.

Sturmey Archer now offers a fixed gear three speed hub, S3X, along the lines of their classic ASC hub from 60 years ago. I have the S3X on one of my bikes and I like it a lot. But it is more like riding a three speed hub than like riding a fixed gear. There's just enough slop in the hub that one can't do track stands or the like, so I don't get quite the same feeling of connection to the road as I do with a simple fixed gear; and having three gears to chose from, I don't have the fixed gear mindset that I must strain to maintain a decent cadence and hammer up every hill. So as much fun as the S3X is, it doesn't actually seem to add to the fixed gear experience.

Nah, it was SS

Don't worry when your change dog wears out on the S3X and you can only use high 95" you will soon remember to hammer up every hill. Oh and the 13 week wait for a new dog to arrive from SA will be good exercise for you too.

Single cog maybe, but not a single speed!
(Anyway I have a second 'gear' for my single speed, they're called feet, 2x12=24".)

Decathlon 's BTwin Tilt, folder range has a model (7 iirc) with this sort of 2 speed auto hub. It's set to switch at 19kmh.

This Tilt has 2 speeds: pedal speed and motor speed...http://www.decathlon.co.uk/tilt-700-eapc-id_8245153.html
