Bike size ID

I am probably looking for 18" though I can probably do OK with 19.5", but
certainly not any larger. I am 5'9.5" with a 33" inseam.

Thanks, Roos

If you're looking for a mountain bike and are 5'9.5" then you should
really be looking at something like a 17" frame.

17" tends to be the "medium" frame size for a lot of manufacturers. Try
a few out in the shops before you buy. A 19.5" frame would probably be
more suited to someone taller.

Don't forget, the fit for a mtb is different to fit for a road bike, as
the geomtries are totally different.

What's your budget by the way? There's a FAQ on the WhatMTB website with
decent beginner bikes listed at lots of price points.

Have a look and see if it helps

I played around with some online calculators, and one came up with
16.5-18.5" and the other with 17-18". The Trek 4100 comes in 16" or
18", so that's how I ended up with 18" I think. But I'll keep in mind that
going up to 19.5" may not be the best idea. And the one in the picture
looks to me like it is at least that size so probably better not.

Budget is preferably under £100, so I'm looking at a second hand most
basic 'proper' entry bike. It's not going to be used that much. I'll just
keep my eyes open for something in our part of the country that fits the
criteria.

I haven't really been looking that hard, just whenever I come across an ad
somewhere I have a look but so far they're all cheese or way too serious
and expensive or very small...

Looks like 18" - 19" centre to centre from a quick comparison with the
wheel diameter

Good luck - You could try the bikemagic and whatmtb forums - They have
classifieds in there, wanted ads too.

Mountain bike geometries from different makers are quite different. You
really need to try one.

Well, it's been bought now, and we'll pick it up later this week and see...

On the one hand it might not be perfect, but (a) if it's all wrong it
should be okay to sell it on but more likely (b) it's mainly only going
to be used for occasional XC forays on landy tracks in lieu of boring
walk-ins so it should be fine for that (at least as good as my old rigid
EBC C-400), and really not much point worrying about spending 2-3 times
as much just to tick some more boxes.
High use and technicality would be a different matter, but this is a
couple of trips a year and mainly something to take tractor tyres and
not fall to bits.
