Sturmey Archer used to make a three speed fixed hub according to an old chap I met in the street twenty years ago. According to him, and I have no reason to doubt him, it was based on their standard 3spd hub and just like the standard hub has a 'neutral' between 1st and 2nd. Anyone who has used a maladjusted Sturmey hub has experienced the testi/toptube interface potential of 'neutral' which is a just the gap between gears. Folks used to adjust them so that they could use it as a freewheel. When one of the top cyclists of the day got herself killed when her gears engaged and bucked her off under a milk van the hub was withdrawn from sale and actually banned in law. You're not allowed to have gears on a fixed wheel.

Fixed gear is having only 1 gear which is irrespective of +/-freewheel. Thus a fixed-gear bike can be both Single-speed (with freewheel) or Fixed-wheel (no freewheel)skwerl said:
No freewheel is Fixed-wheel.

Fixedgear/fixedwheel=no freewheel. A bike with a freewheel isn't a fixedwheel. Simple.
They did indeed make a three-speed fixed hub, called the ASC. I have one from 1951.mickle said:
I'm not sure the rest of this is true, though - it doesn't have a neutral anywhere unless it has been bodged, it was sold to time triallists for winter training so there was no sense in buying Sturmey's specialist fixed hub and then making it freewheel, it wasn't withdrawn from sale and I'm never seen anything about it being banned.
If it is illegal, mickle, I'd like to see chapter and verse.

I have no evidence, just the word of a long dead old codger. The neutral was a bodge according to him, by adjusting the cable to allow use of the tiny gap between 1st and 2nd as a freewheel.

hmm. I seem to remember being one of the original contributors to that site. I remember it's birth from C+. Didn't put that comment in though.
Just cos you read that definition on a website doesn't make it right. Convention says otherwise. Convention doesn't have to be exact so fixed vs s/s may not technically be correct enough but the majority of riders will go with fixed* being the non-freewheeling and a s/s being the other, useless version.
To be pedantic I think you'd probably opt for 'single-gear' fixed or single-gear freewheel vs multi-gear freewheel (ie derailleur, hub-gear etc)

Fixed means not free(wheel). 'S/S' assumes a freewheel. 'Fixed' assumes one gear. End of.

We might just have to agree to differ.
I personally wouldn't listen to the doubters. I think this is a lovely idea for a project and I think you should give it a go. Ignore the received wisdom, if you think you can make it work then who is anybody else to say that you aren't going to succeed?! This 'chain suck' that is spoke of probably exists but I wouldn't have thought you would get it unless you actually try and brake by back-pedalling. Just install (keep) brakes and use them in the normal way.
To think where we would be in this world without cyclists with a bit of innovation... christ - it's a rum poor do if they just get slapped down!

The fact that bonj thinks it is a lovely project should make you wary, Yellow Fang.
Chain suck isn't an inconvenience on a fixed wheel, it's a what my Norton Owners Club manual used to call "a grave danger i.e. a danger which may lead to the grave". If your chain stops running for any reason, the back wheel stops going round. Instantly. You carry on down the road at whatever speed you were doing, often on melting rubber and with no steering. At best you will wreck a tyre and your rear mech, at worst you will kill yourself.
There are lots of things you can experiment with on a bike, cheered on by people who know diddly squat about fixed wheel riding. This is not one.
