120 kph is 75 mph.

Does anyone know where in PP I can buy a 29er mtb rim with 36 holes for the spokes ?

Most rims are 32 hole these days, but the rear hub motor I want to use is 36 hole

I can get a Sunringle MTX33 29er 36 hole rim for $50 from an Alibaba seller, but shipping is an extra $316 via UPS. Thats a non starter until the normal postal system starts working again and I can use a cheaper shipping option.

Have you checked with the used bike dealers on facebook they have lots of parts. Also if you are using disc brakes then using a smaller rim size will work just fine no mods needed.

You do know that you can lace a 36 hole hub to a 32 hole rim, right ?

Thanks for that info.
I ordered some stuff off Aliexpress 2 months ago using Sellers Shipping Method. Tracking shows it left China within a few days, but no updates since then. I guess it got to some sort of hub in Singapore and is now in a big pile waiting for flights to resume to Cambodia.

The 36 hole hub to 32 hole rim spoking is interesting. I book marked that but will probably just wait until I can get a 36 hole rim from somewhere.

Finding a used 36 hole rim in PP is one thing, but a used 29er 36 hole might be a big ask ?
Some of the roads in my area/province are quite bad, hence why I want to stick with a 29er rim and ideally tubeless so I can run lower pressure.
The donor bike will be a 29er hardtail mtb.

Not sure if you can get anything from the US, Last Friday I got some stuff via Amazon/DHL delivered in 2 working days despite the warning it might take longer than usual.

DHL/Fedex/UPS still work.
However a 29inch rim, albeit light weight, is very bulky so I expect the shipping by courier from the states would be similar to UPS from China, ie several hundred dollars.

My rim with the spokes to lace my motor to it was $50. shipping using FedEx from the US
