Single Speed / Fixies

Considering getting one of these for a sort of winter commuting bike.....the only problem is none i have looked at tell you the size of the crank ring. All have details on the rear sprocket...
Do these bikes all have a standard size front ring? Or is it a case of asking about each one???

usual can be 42/16-18. but seen higher and lower.
you can always change the chain ring after if you want something different.
which bike did you have in mind?

Max out at 30-31 mph on a flat (130 RPM)
It can be a bit harsh on the knees if you plan on doing ascents, some hills have me down to 5 - 8mph all the way up which is about 20 - 30 RPM!
I previous had 48/18 (70 GI) which is probably the highest you'll need, yes you spin out on most descents but you can maintain decent speeds on flats and climb big hills no problem
I'm looking in to buying a internal gear hub, 3 gears will be perfect for me
This site is very useful for finding out the perfect ration for you

Gearing sounds odd at 55/22 but it is a 68" gear about the same as 44/17 which is common off the shelf setup

I think around 70" is fairly normal but it will vary maybe a tooth either side or that front/back.

The one i'm looking at has an 18 at the back.....i'm just wondering if 42 at the front will be too small? My commute is flat as a pancake, but what i'm looking for is trying to keep the fitness up over the winter...
This is the bike i'm looking at....say what you want about how ugly it is, but i reckon it's bloody gorgeous!
Okay then: it's bloody hideous.
My SS is 50/18, which is a nice commuting compromise for my flat commute.
How about heading to an Evans in the City and trying out different ratios? That way you at least get a flavour for what speed you will be pulling on the flat... Personally the hills wouldnt be a problem.. but spinning out on the flat would be very dissapointing!!

you realise that's 200rpm don't you?
Hill near me I hit 35Mph on and was pedalling all the way : equated to 172RPM ! Was a bit mental but quite amusing for that short time.

Also did a dlub run which totalled 80+miles, rest of the guys were geared and where we turned for home we had a howling tailwind - I was told we were frequently at 35Mph+ and after trying to keep up for probably 15 miles my legs started falling to bits, there was only so far I could keep going like that, on a geared bike I'd have kept up fine.
I run a Trek SS with 44x17 which is 68" and for me it's about a perfect balance for a hilly 17 mile commute, one way I spin out a fair bit and the other I have a good few grinding climbs but on balance I couldn't get away with anything more than 16 on the rear for the ascents, but I'd be able to pedal a few of the descents a bit quicker.
Depends on the route you'll take and your fitness as to what gears you'll need.
Common bike, the Langster, has 42 x 16 = 69.25" so a tiny bit higher than mine.
25Mph for example = 121 RPM, 20 = 97RPM.
I run 48/18 with a 28mm rear tyre which I think gives me around 71in. That suits me fine for general riding around here.
managed to do a 5h 33m 100mile ride on it a few weeks ago, passing hundreds of thousands of pounds worth of gears on the way

I always said that there are actually 3 gears on a so-called single-fixed bike: sitting down; standing up; and the 24" universal gear
Edinburgh have the Langster on offer at the moment. I think they call it their red-label sale, or something like that. Reduced from 499.99GBP to 399.99GBP. I won't be bothering as I've got my eyes on a Genesis.

White, white, and more white. I hope you enjoy cleaning!
Single speed hipsters and road riding are completely different IMO. You said that you want to use it to commute - maybe the commuter forum would be better?
Anyway - check this out - and revel in your "bloody gorgeous" bike!!

The orange and white bike that appeared in an earlier post can't possibly be a single-speed-hipster. It's got more than one caliper brake.
