So after some 65000km it was time to replace the rear break pads (yes I know, I should be using the front break more). This is just to inform you that they were very easy to replace, especially if you already are used to replace break pads on cars.
However, the break parts seems to be Niu parts, and not generic parts. At least in Sweden there is on second source and the mail dealer asks roughly 90usd and 70usd for the front and rear breaks pads, respectively.
Any tips on cheaper break pads that can be bought in Europe would be highly appreciated.
