It's just the standard "Hailong Max" battery cradle. With a 48v 20Ah battery you ideally need 3 attachment points on the down tube. Lots of posts here how to do it search for rivnuts. You sometimes need to lengthen the slots on the battery cradle

If you wanted a step through frame with disc brakes, there is the Cannondale adventure but they are quite rare https://www.facebook.com/share/14G4wZYNoz6/ There are lots of Carrera crossfire low step bikes with disc brakes that are usually <£100 for a nearly new example. I have converted...

I think that kit is powerful enough to warrant a torque arm

Yep installation, follow same steps. Might or might not have compatible plug, if not, it's just connect the output 2 wires from the battery to the controller input. Just make sure whatever method you use doesn't just rely on the bare wire connection (I crimp then and then use insulation tape...

That looks a suitable donor bike. If you follow the link in the 1st post that has a 250w rated 48v rear hub cassette wheel with 17 amp kt display/controller ( that's roughly 850 watts peak power from the controller !). Choose correct wheel size 29 in ? I would pair that with a 48v 20ah battery...

Nice Bikes ! Yes - 73mm bottom bracket - standard(ish) mtb size So you could fit a mid drive - you would need to know whether the bottom bracket was press fit or BSA and if it was press fit what sort of press fit. Bafang BBS01, Tongsheng TSDZ2 or the Woosh TSDZ8 are all 250W rated. You'd...

Have you got a luggage scales (the ones with a hook on them that you attach the luggage to ) I predict 19kg including the battery

That's brilliant ! It will fit quite wide tyres, that you could run a lower pressure. I have 2.15" ones on the one i did for my son. I was wondering about these for the one I am building for my elder son ? https://winstanleysbikes.co.uk/maxxis-minion-dhr-ii-20-inch-clincher-tyre?

Sorry, I was trying to answer this post For a press fit bottom bracket you need an adapter - if yours is a BSA bottom bracket you don't

I know this is for bafang mid drive motors, but basically recommends 2 specific press fit adapters PF30 to BSA and BB30 to BSA. Once the adapter is fitted (so its now a BSA bottom bracket) I would think the TSDZ2B would fit ( I have that adapter PF30 to BSA on my Bafang BBS mid drive bike and...

Thats great - another convert ! Happy pedelecing

In that case I would probably go for the Yosepower 250W rear cassette with battery - unfortunately they are out of stock of 26" wheels at the minute. The Woosh kits I have used have a better controller than the Yosepower 250W kits and are slightly more powerful (17-18a vs 15a). They also do...

Intermediate level off road, I would certainly consider a mid drive. How heavy are you ? You mention the roads out of the village - when you are off road do you feel you need the assist. The efficiency of the hub motors you are considering starts to fall rapidly once you are going less than...

Are you setting a record time between your 1st and 2nd conversions :) I would go for the LCD 5 out of those options, you'll need a 48v battery too. Don't think you need to solder anything I wouldn't fit that one on a rim brake bike - it will be significantly more powerful than the Yosepower one

That's really annoying, especially when you've got it "just right" Interesting that it seems targeted ! Obviously someone else was impressed with it !

I just ordered this one yesterday for my sister's Birthday present https://a.aliexpress.com/_EJ51WaE Is that the same, but I think yours is a cheaper price I looked at the internal cable routed ones, but wasn't keen on drilling her frame, and the external cable routed ones, but the collar was...

Swap over to KT controller and display ?

Brilliant, so £400.including donor bike with hydraulic disk brakes, and , as you say you've still got your original bike. Eta the 250w Yosepower kit is slightly stronger up hills than the 350w Let us know how you get on with it when you get the bracket The question is how long until you...

That looks brilliant. I'm going to do another one for my eldest son later in the year, I will nick that idea
