is this what I need to swap wheel out from off turbo trainer to outside? Got the tyre, just need a tube and .... last question, do i need the speed disc rotor thingy?
It's quick release so should be simple to do.
My actual bike is the one in the my picture.

Rear wheel with gears and tyre size. The cassette has 7 cogs so I'd want the 7 gear size?

Your bike already has a rear wheel, why do you want another one?

If like me you still use the bike for riding outside its nice to have a wheel as a dedicated turbo wheel with a turbo tyre on it.

So she can just swap out the wheel to ride outdoors rather than having to swap the tyre from the turbo one

That advert is for a wheel - with a disk brake rotor. As Skipdiver says, you've got a wheel! And the bike has a V brake. If you're looking for a second wheel to swap the critical data is the 650B, which is a standard, but not a common one in the uk. You need a wheel with a compatible rim - i.e. 650B. The other essential data is the 48-584. 48 is the width of the tyre in mm. 584 is the diameter of the bead rim seat (where the tyre interfaces with the rim. If you want a quick swap you need a wheel with the same rim (look for the 650B or ETRTO 584). It's also helpful if the rim is the same width as it avoids needing to adjust brakes. You don't need a disk brake wheel. Inner tubes are a bit more forgiving, but again, search for 650B. But I think any MTB (26 inch) tube would probably do.

I would have thought it was a lot easier and cheaper to just leave a hack bike bolted permanently to the turbo trainer and not keep swapping things around!

That's possibly her only bike however...

@SkipdiverJohn it may be that they only have the one bike

Brown's Law Of Tire Sizing:
If two tires are marked with sizes that are mathematically equal,
but one is expressed as a decimal and the other as a fraction,
these two tires will not be interchangeable.

The ad says the wheel is suitable for disc and rim brakes, it also says you will need to pay extra for the rotor if you require one

 

[Edgy Dee]

Hum... just had a thought - is the existing wheel a 650B? Have you got the right tyre? I think we need to see the size data on the original wheel/tyre please.

So yes, you could get the 650b, without rotor... IF your existing wheel is indeed a 650b! It's not a common size.
