They're 650c not 26". Planet X do have some of these though. http://www.planetx.co.uk/i/q/TYSCMDT/schwalbe-marathon-dureme-evo-folding-tyre They are cheap but very hard wearing and you won't get a puncture unless you roll over an IED.
They are out of stock for the 26" 40mm version - were they in stock when you posted or was just the 26" 2" version available - if you can remember? A little gutted.

This may be a compete novice's question (well it is) but if my bike came with, as standard, a 2.1" tyre and the inner tubes and rims to fit that width tyre then:
1) If I were to change the tyre width to 1 3/8" would I need to get a new inner tube to fit the 1 3/8" tyre and slimmer rims or will the inner tube and rims handle the 1 3/8" tyre?
2) What is the max size up and down I could fit onto an inner tube and rim designed for a 2.1" width tyre?

Thank you.

If you are talking about a 26 by 1 3/8" size it is an old 26 fraction tyre and won't fit on your mtb.
Rear on this bike is a 26x1 3/8 and front 26x1.35

So these in a 26" X 1 3/8 won't fit the wheels on my BeOne Spirit Sport (link in the first post)?

Would these 26" x 2" be suited to my bike rims and inner tubes? I would imagine so as my bike's original tyre is 26" x 2.1".

I would like a narrower tyre for road use but without having to replace the inner tube and rims, is there a narrower tyre I could use on my original inner tubes and rims?

Thank you for your effort in posting a picture for example purposes.
 
The front wheel of bike in my pic is a standard 26" mtb wheel. That rim has also had a 2" wide tyre on it in the past.
You need the modern 26 decimal tyre. For eg : 26x1.5
If tyre size quoted in fraction it will not fit. The old fraction is similar in size to a 700 wheel.

Ok, I understand now. How narrow can I go on a tyre that will fit my original rim and inner tube? Would a 1.25, or no less than a 1.50 width to fit an original 2.1"?
 
Typical mtb 26 tube will be for tyres 1.5-2.5 wide. There's alot of tube to squeeze into a 1.5 tyre and easy to pinch when fitting.
You can get pr cityjets and narrow tubes for around £24 from Helfrauds.
1.25 tyres will fit onto your rims but definitely recommend narrower tubes with them
