I understand 250w is the legal maximum for use on public roads.

Yes but my farts have more power that a 250w motor . If you ride like an idiot you might get stopped . Ride normal you will never have a problem.

You may well be right, but the OP appears not to be very knowledgeable on the subject and this is something he needs to know. Especially as

cannot offer any guarantees.

Personally I think MTB are best for conversion because they are strong and much more comfy

I converted cross bike last year. Used a Bafang mid-drive motor 36v 250w with Samsung battery pack and 860c display from Greenergy Electric Bike store on Aliexpress.

Mid -drive motors give more torque for the power. Kit comes with everything you need and there are a few videos which show you the process and is fairly straight forward (except for the bottom bracket removal tool they include). Ordered it from Greenergy as kits in UK were all sold out and Greenergy included customs charges etc

Very pleased with it. The 860c display gives up to 9 levels of pedal assist. If going up a very steep bank, you do need to put in quite a bit of physical effort but the vast majority of the time on the road 36v 250w gives an easy ride.

That type of bike would suit a rear hub motor of 750-1000w . Lots of room for a big 50v battery and controllers .
It’s it was a hardtail mountain with front suspension I would recommend a mid drive Bafang motor and big battery .
Kits for hub motors are around £500-£750
Kits for Bafang £750-£1000
Just depends on which accessories you add and what battery you pick .

You should of gone with a 750w Bafang

Not really. Everyone has different requirements. They are not road legal and most of my use is on the road or cycle lanes and 250w works fine for road use (and you still get some pleasant exercise). If I want speed and power, I use my motorbike which is way more than 750w (edited)

Yose power make good hubs, front or rear, they seem to be the market leader for aftermarket retro fit

rear wheel is consider best, they do 36v, 250W or 350W (which have internal gears , so climb better)
they also do the physically larger 500w to 1000w non geared 48V hubs, which are way over powered

the internal gear hubs may seem low on power but they have more torque due to the gears, plus take less volts

make sure your dropouts are wide enough to take the new hub

im tempted to get a YOSE 36v 350 rear hub 27.5 inch wheel for about 230 on ebay, i already have a 36 v battery

try and get a real samsung battery, 36V 7.8AH should get you easily 10 miles plus (which is about the smallest bettery you can go for) (edited)

I am interested in converting my MTB myself so interesting thread.

Many thanks @yozzman1234 @Pandamansays @Mark_Hickman - as I'm just going to be doing local city runs, I'm happy with a 250W motor or nearabouts (happy to plead ignorance if it's just over). As it's not in use daily I'm just considering the most cost-effective kit just to give me a nudge to use the bike when the conditions aren't great - as around here there's a very strong headwind whichever direction you cycle in...

Any tips on how I identify the right kit and supplier would be much appreciated.

PS I'm guessing I would get laughed out of the forum if I mentioned the Rubbee X rubbee.co.uk/pro…-x/ as an alternative option for a lightweight cyclist...?
