An automatic two-speed SingleSpeed - oh my!

[Andrew_Culture]

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...

I didn't get on it because it's voodoo, and a 2-speed single speed defies the laws of the universe. It might have been while you were taking it for a spin but James(?) was explaining that it worked with a centrifugal clutch. Which I suppose explains another curious thing about it: the moment you stop pedalling it changes down and not just when you slow down to 9mph. I twigged immediately that the centrifugal clutch bit was simply a ruse for covering up the witchcraft, though.

It was good to meet you @Andrew_Culture and @dktd - and fab to see @deptfordmarmoset obvs! (Sorry I didnt make the Sunday London Ride - I was gadding about Berkshire on my Brommie) http://www.the5milecyclist.com/apps/blog/show/42028668-brommie-miles-around-reading-30-03-14

The next time you are in London you should pop into http://www.velorution.com/ as they have some amazing range of unusual bicycles. Definitely not cheap but definitely interesting .

Oh the Velorution stand was one of my favourites, I gave it a special mention here - http://cycling-health-tips.blogspot.co.uk/2014/03/velorution-spin-london.html

Was charming to meet you

Been around for years. Dead popular on town bikes in that Europe. Sachs does em iirc and there are different spring rates to determine the speed at which the shift happens yes?

Only if you take them apart!

I think if I wanted to have a simple 2sp hub on my singlespeed, I'd prefer the manual kick-shift of the Sturmey Archer S2

Should have a fixed instead. Don't need any of those shenanigan's .

Two different models I think.

Cheap nasty unreliable pos. Steer well clear unless you like carrying your bike to the nearest railway station on a Good Friday morning.

That is chuffin' gorgeous.

Do you know whether it works on the same centrifugal clutch principle?

I regret seeing that because I want one now...

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