Able to take tyres up to 65mm.
The one reviewer says he used one to fit an Alphine hub on a Tern D8 (I know nothing about Tern's!). Also available in 36 spoke version.
Ryde were formerly Rigida, so decent quality.

Thanks, yes that does help. I have 28H and 32H rear hubs, 18H and 28H front hubs - 28H are Tern, the others are original Dahon Kinetix. I'll have to see what 74mm front hubs are available from Shimano and others. I should buy a front rim plus other bits soon before I need them - managed to buy an entire spare new rear wheel on for less than the price of any of those rims late last year, still haven't got around to installing it; spokes might be rubbish, it's bound to need truing (they all have so far). I think the widest tyre I can fit on my frame is not much wider than 2.125", wider may result in woolly handling anyway?

You guys always make things so difficult and expensive. I've never used any rims other than the cheapest ones I can find on Ebay and Amazon. I have never had a single issue with any of them - no corrosion, no spokes coming loose, no denting , no cracking, no truing necessary. That's building always with 14g spokes, if that makes a difference. I always ride up and down curbs and on rough trails. I've also hit many potholes.

Be careful of rims with eyelets in the holes, especially if you plan to use 13g spokes, because they tend to hold the spokes at right angles to the rim. Either use 14g spokes and nipples or don't have eyelets.

Thanks, very useful hearing your experienced perspective regarding the cheapos and eyelets. I'l have another good look around on the internet's Chinatown.

32H hubs for 74mm and rim brake are really rare. So far, I've found this one. They probably don't deliver to the UK.

I need to fit a new rim to my front yose hub wheel.
I unsure if it's something I can tackle or if I should just find a local shop to do it?
Problem is I've been running rim brakes so I'm going to upgrade to discs. Reading through it seems there is lots to consider when buying a rim and getting the correct spokes.
I wonder if easier to buy a new hub wheel?

fitting and trueing spokes in a new rim is a doddle if your methodical about it, getting the right spoke size is the main hurdle, I got that wrong a few times so by the time the right size arrived I was well practiced and it took no time..

useing onlne spoke calculators might be a good idea..

using upturned front forks and cable ties snipped to size makes a diy trueing frame that just needs an upturned bucket for a stool to sit on while you get the wheel round..

youtube fed me all i needed from suggesting diy hub stands to get started to stressing the wheel when 'first done' and retesting spoke tension listening for the same spoke twangs..

btw all spoke sets i got had EXACTLY 36x nipples be mindful not to loose any

It is one of the great learning experiences with an ebike. You only need to do one and you'll have all the learning, and every step of the way there are plenty of people here who can help.

First find a rim, then calculate the spoke length required, and so on. The build is not hard, just a bit slow the first time.

Post details of the existing motor, rim etc. to get the conversation started.

I guess you need the technical measurements for the extract motor?

You can measure the motor and rim with a piece of cardboard a pencil and a ruler.

I absolutely agree with cadence, steel rims and rim brakes are a lethal combination. (How did our parents ever survive long enough for us to exist?)

We rode at much slower speeds, most cycling was typically at 10 mph, none of today's barmy belting around helmeted at 20 mph or more.

Update.
Ordered a new wheel from @Woosh.Andy was helpful.
Should go straight on then I can repair the current yose wheel which will be a spare.
Will update my progress for interest

Here is a picture of my current rim with sizes. Any guidance on what rim is required would be appreciated.

The critical measurement for a 26" wheel is the 559 (mm bead diameter)

The choice of width depends on how wide a tyre you want to fit, but not so much need for exact match.
For example see the table in https://www.schwalbe.com/en/technology-faq/tire-dimensions/

Remember the tyre width will be limited by the frame clearance as well.
