Missus left her bike outside a local shop, today, while she went in to buy some stuff.
The bike was locked but some r-sole decided to take advantage of the quick-release seat adjuster to nick the saddle and seat-post.
Kind of annoying because I wouldn't be surprised if it was just done "for the lulz" and the saddle's probably in a hedge somewhere nearby.

Anyway, I measured the frame tube and thought "Okay, it's about 28mm", and went online to order a replacement, which is where things became tricky.
Turns out that 27.2mm and 28.6mm are both fairly common sizes for a seat-post and I'm not certain what size it needs.

The bike's a MuddyFox Recoil 26.

Anybody know, for sure, what size seat-post it'll be?

You measure diameter inside a seat tube to know what diameter of a seatpost you need. You need calipers to measure inside tube diameter correctly. You measure outside diameter of a seat tube to know what size of clamp you need. In the second case it's not always 100% matching with available clamp sizes, then you pick which one is the closest one. If it's between two standard sizes go for a bigger one.

P.S. I've checked the bike model. It's a rather budget line of products, isn't it :) Which means manufacturer even on their own website provides literally no details about geometry. You will have to measure it correctly yourself, or just pop into your local bike store and just ask politely what size of seatpost will fit. It would probably be even cheaper to just buy locally than shop online.

My "local bike shop" is 80 miles away, for a 160 mile round-trip.... to buy an item that's about £15 off the interweb.

I was hoping that MuddyFox uses a standard seat-post size across all their range, which somebody might know.

Failing that, I suppose I could phone up a bike shop and pester them for info'.... and then buy a suitable item off the internet.

As Caramel said, measure the inside diameter for seatposts. It's v. probably 27.2, that is by far the most common. Worst case you can sent the post back and get the alternate if you order via the web. You can also look for secure seatpost clamps as well - for urban use the seat quick release is pretty pointless.

Why not contact Muddyfox to ask if they sell the piece directly ?

I'm guessing you haven't looked at that very closely? ;)

You have to pick from a very limited range of topics and then, when you submit a question, you have to include your "order reference" (and you can't just enter "not applicable" in the box).
Seems like MuddyFox only want to hear from new customers, relating to online orders. :(

I guess I'll just phone a bike-shop tomorrow and see if they can help.

Annoyingly, speaking as an engineer (who does understand the difference between th ID and OD of a tube) I normally have a digital vernier caliper for this stuff but, alas, I got something nasty on mine a few days ago and killed the display so I'm currently waiting for a replacement to arrive.
It occured to me that I could get a short length of tube/bar, turn it down until it's a suitable fit inside the frame-tube and then measure that with a micrometer but, jeez, that's a lot of faff when you'd think the information would be fairly easy to find.

Ah ok, I thought you could try to send an email directly without going through the site.

This kind of information is usually very easy to find when it comes to big reputable bike manufacturers. You get a whole schematics of geometry with a sheet full of values and parameters. Unfortunately brands like MuddyFox are on different kind of market, if you know what I mean. It is very likely they use whatever is the industry standard because it simplifies and makes everything cheaper for them, but it wouldn't be new for the kind of brand to have some very proprietary part dimensions for absolutely no apparent reason.
